The display fuzzy reasons and processing

The screen displays the ambiguity is one of the common faults of various displays, its causes has three main aspects:

1, Loose or shift during transport or use by the vibration leaving the FBT (line output transformer) focus potentiometer, resulting in added to the CRT focus voltage change (deviation from factory good debugging optimal voltage value), resulting in the screen vague;
2, the use of environmental humidity, so that the the focus pin CRT tailstock board discharge ring (half ball) rust, CRT powered blurring;

3, CRT tube internal manufacturing process or CRT pyramidal glass bulb debris of focus (focuse) pole and accelerating electrode (G2) between electrostatic dust, the formation of polar resistance of the screen is a serious blurring.

How to judge according to the a fuzzy screen the phenomenon is what causes it?

The first look at the degree of blur screen blur lighter, only the character outline thicker, and the writing was still able to identify, caused mostly the first reason; seriously obscure character large area, the screen is a white halo The character has been unable to identify and screen brightness changes, is a third reason for the tune focus potentiometer on FBT; the CRT just-machine vague with time increasingly clear screen character, which is usually for a second reason.

Clear screen vague reasons, and how to troubleshoot it based on the failure phenomenon?

In the first case, open the cover, the potentiometer to fine-tune the FBT Focus (focuse) troubleshooting. As for the the tail board Focus the pin discharge ring rust processing, general use the anhydrous alcohol cleaning discharge ring and tailstock electrode plugs and sockets, as serious ring rust discharge, replacement of the tailstock components. The third cause the screen fuzzy approach: remove the the CRT the tailstock board, CRT on the high hat 24KV high voltage with a multimeter pen line (best to use better insulation performance digital multimeter) lead to the CRT focusing plate socket turn on the monitor to AC power, and 2 to 3 times with a grounded table pen line on the accelerating electrode (G2) plug instantaneous discharge (preferably on a CRT G2 plug with an external protection sleeve short lead out lead line on the instant discharge operations).

Generally after 2 to 3 times of the discharge process, it will cause the focus (focuse) and accelerating electrode (G2) electrode resistance between the two electrodes of the dust breakdown. After the restoration of the original circuit, the clarity of the observation screen character or graphic display, if necessary, appropriate adjustment to the focus potentiometer on FBT can make the fuzzy troubleshooting. This method often called "the fight Acking Law, it comes to high-voltage operation, should be careful, remember to protect the safety of personnel and equipment.

Described above screen display fuzzy fault, not including those improper pole (G2) voltage regulator, brightness, contrast potentiometer adjustment position does not fit the screen caused by disorders such as acceleration, seem layer of fog Meng Meng feeling the situation is taken into account. For monitor IBM 2248/G03, Envision/D350, aligned with the middle part of the CRT screen gently with a rubber hammer hitting several five percent certainty exclude such displays of fuzzy fault This is certainly fuzzy failure shortcut road repair monitor .

Notebook graphics card Introduction- ATI

ATI laptop graphics has as Intel as unshakable as AMD by Turion64 the front toward the Intel cut, ATI being a strong challenge from NVIDIA, Intel and many other opponents. But the boss is the boss, the ATI product line camp really pack a large pool: AGP's Mobility Radeon-based system: 9200,9600,9700,9800, based on the PCI-E, Department of Mobility Radeon X: X300, X600, X700, X800 X1300, X1600 and integrated XPress200 are different.
1.Mobility the Radeon 9000/9200, Features support for DX8
After "radium" and 7500, inherited the glory of the radium family, 2002, ATI launched the world look forward to the Mobility Radeon 9000 and 9200 two. Mobility Radeon 9000-based desktop Radeon 9000 chip kernel development from the core frequency of 250MHz, memory frequency of 460MHz, and also specifically for the CAD / CAM, DCC, has been optimized, and this is also the world's first fully supports Direct X 8.1 professional mobile graphics chip NVIDIA Quadro4 Go GL strong competitors. In terms of energy-saving technology, Mobility Radeon 9000 using the improved third generation of the PowerPlay "power management technology.
9200 code for the M9 + 9000 an improved version of the desktop-class Radeon9200, the biggest improvement is to increase support for AGP 8x. In addition, 9200 is also a corresponding increase in core frequency and memory frequency, the core frequency of 270MHz, memory frequency of 540MHz DDR, the same, the third generation of the PowerPlay power management technology.

Although the products released in 2002, until today, which in many books, we can see the presence of Mobility Radeon 9000/9200. Remember the phrase "4880! Notebooks to mention to go home!" The famous slogan? This notebook is the Shenzhou Cheng Long A220E, it is equipped with 64M ATI R9000 discrete graphics, with the mobile version of AMD Athlon XP-M processor 2200 +, 5000 multisection 3DMark01 score, play 3D games such as Warcraft, CS basically no problem. called for minimum standards for equipment, games Friends of tailored.
2. Mobility Radeon 9600/9600pro, Characteristic support DX9
Mobility Radeon 9000/9200 does not support DX9, ATI followed in March 2003 officially launched the Mobility Radeon 9600 series, the project code-named the M10. The launch has also created a series Mobility Radeon several firsts: the first one to support DX9 mobile graphics chip; the first time to take a 0.13μm process; first piece can support up to 128MB video memory graphics chip.
9600/9600pro are based on the development of desktop-class Radeon 9600 (codenamed RV350), hardware architecture is almost the same, but also improved memory controller and integrated within the new version of Hyper-Z compression technology . The main difference is still the core frequency and memory frequency. They are ATI's high-end mobile 3D graphics chip, using four pixel channel, four vertex engines, you can support Microsoft DirectX 9.0 and the latest OpenGL to provide more advanced anti-aliasing and anisotropic filtering, can provide a film the effect of image and excellent 3D performance from the evaluation results, 9600 3Dmark01 score of 8000-9000 the standard.
9600 the maximum support to 128M memory should be able to cope with today's mainstream games, at least in the number of books using these chips, however, often up to only assigned to 64M. Furthermore, the graphics chip, memory frequency do not increase, addition, 9600 seem to have ATI into a tendency to heat large, plus the framework of limitations, so that 9600 is destined soon to be thrown into history.
3.Mobility Radeon 9700/9700SE ATI's most successful products
Mobility Radeon 9700 is the current notebook notebook discrete graphics in the desktop graphics chip, 9700 to help ATI to hit a nice turnaround for the first time ahead of an nVidia. However, Mobility Radeon 9700 is not the Desktop 9700 mobile version. Mobility Radeon 9700 is actually taken 4 rendering pipelines design of the RV360 Radeon 9600XT, using the 9700 naming, in fact, with the famous brilliant desktop 9700.
In early 2004, ATI Mobility Radeon 9700 graphics chip, the project code-named the M11. In the process, the Mobility Radeon 9700 using the 0.13μm Low-k (low dielectric constant insulator) process to produce, which makes the M11 in less heat compared with the M10 in the work of the same frequency, or that the heat in the same circumstances can work at higher frequencies. With the Low-k technology, making the Mobility Radeon 9700's core frequency to further improve the reach 450MHz, memory frequency can reach 520MHz.
Relative to the Mobility Radeon 9600Pro, its performance has been considerable progress in 3DMark01 scores can break a million mark. Allows you to 1024x768 resolution, smooth running Halo (Halo) and cell division. As for the Mobility Radeon 9700SE (also known as the Mobility Radeon 9500), in fact, is the reduced frequency version of the Mobility Radeon 9700, the core frequency from 450MHz down to 250MHz, memory frequency from 520MHz down to 400MHz. Both products are energy-saving technologies, the fourth generation of the PowerPlay technology. At the same frequency, the 9700 is better than the 9600 heat control. According to the evaluation, in actual use, the 9600 350MHz runtime power consumption of about 7-8W in the same power consumption, the 9700 can run in 400MHz and in the case of standby power consumption significantly reduced to 1W.
Configured with 64MB of video memory, ATI Mobility Radeon 9700 graphics chip, to cope with FIFIA 2005 "," CS "," Warcraft "game at ease, to reduce some of the details, even when running Need for Speed ​​Underground also evident.
In August the same year, ATI Mobility Radeon 9800, it is the same with the 9700 process, but with eight rendering pipelines and 4 vertex shaders and 256bit memory bandwidth, 256MB of memory, the frequency of 350MHz/600MHz. Its project code-named M18, is based on the desktop Radeon 9800 graphics chip, with all of its features, including technologies such as Displacement mapping. In addition, the 9800 uses a 0.13μm Low-k process of production, and the fifth generation of the PowerPlay "power management technology, relatively good control of power consumption, providing end users with the top graphics performance. Called Mobility Radeon9800, but they are using the X800 core architecture, Mobility Radeon X-series of mobile graphics chips will be left to the PCI Express interface, so ATI the Mobility Radeon9800 to the Fengyun core. And X800 series graphics card, Mobility Radeon9800 Long Shader 2.0 instructions and 3Dc texture compression technology. For a laptop, the X800 core, the 9800 seems to be overkill, because even if the ability to Dothan, can not take full advantage of the strength of 9800? Turion64 better? We really need so fast? Moreover, in this case, people will tend to choose the X800. I know, really used this card notebook seems not to sell.
The 9700 series is ATI's AGP era of great success with the final glory. 9800 is the ill-fated, for now, this is only a symbolic significance than practical significance graphics card. So far, we never saw the ATI AGP on other actions. AGP era really is this the end?
4 Mobility Radeon X300 to explore the era of PCI-E
With the advent of the Intel Centrino 2, and naturally the PCI Express bus is the introduction of the mobile platform, ATI reaction that sensitive, once again took the lead with their mobile chip on the Sonoma platform. This is the entry-level PCI-E mobile graphics Mobility Radeon X300 from ATI. The project code-named M22, Mobility Radeon9200 (M9 +), using the RV370 core architecture and 0.13μm manufacturing process. Technically full support for DirectX 9.0b and OpenGL 2.0, with 4 3D rendering pipelines and 2 vertex shaders support LCD Enhancement Engine technology to support HyperMemory technology enables chip via PCI Express high-speed architecture borrow system memory as video memory SMOOTHVISION 2.1, while support to eliminate the jagged edges of the object, to improve image quality. In energy efficiency, X300 has been adopted to the fifth generation of ATi Powerplay power management technology.
It can be seen, not advanced, the basic framework of the X300 (M9 +) did not use a 0.13μm Low-k technology, but thanks to the development of technology, the Mobility Radeon X300 core frequency is still to reach 350MHz with the Mobility Radeon 9600 Pro flat memory frequency reached 600MHz, it is almost reached the level of the Mobility Radeon 9800. Thus, although the Mobility Radeon X300 is the entry-level mobile graphics chips, but performance is still strong, some technologies are not applied in the later X600, a shot of its performance is close to 9600. The charm of the PCI-E may be here?
Time IBM T42 2378FVU (64MB Mobility Radeon 9600) and T43 266846U (64MB Mobility Radeon X300) of the test, 3DMarks05 test results: the T43 710, T42 - 68; 3DMark01 test results: T42 - 9751, T43 7021. From the test results is not difficult to find in a new generation of DX9 engine design 3D applications, the actual performance of the Mobility Radeon X300 is slightly higher than the Mobility Radeon 9600 chip, but in the environment of relatively old 3D engine (DX8 standards), the Mobility Radeon X300 did not account for the slightest step on the foot of the cheap, but rather to the Mobility Radeon 9600.
X300 ATI in the beginning of the PCI-E, although can be seen from the above test, the X300's lack of PCI-E is indeed remarkable potential, is the right direction of development. This is why ATI in 9800 did not continue AGP series products of reason. X300, such as the lack of unique FullStream people plagued with massive image offline viewing streaming media files, VideoShader is the most advanced video quality and optimal power to play DVD discs In addition, "automatic display configuration" (ADC), Vari-Bright has efficacy. For notebook users seeking stable 2D and advanced 3D graphics performance, the X300 graphics accelerator can be described as the ideal solution. Striving for you? Think about it, big brother IBM selected the most important T-series, can be wrong?
5. Mobility Radeon X600/X700 build the backbone of the PCI-E
Since the X300 is not too strong for 9600, PCI-E is the development direction, tasted the sweetness of the ATI X300 on a project code-named M24's Mobility Radeon X600 was released in September 2004, intended to replace the Mobility Radeon 9600/9 700, positioning in the end. The X600 is based entirely on the PCI Express technology, designed for notebook computer designed graphics chip, the hardware supports Direct X 9.0. Take into account the particularity of the notebook, the Mobility Radeon X600 ATI notebook dedicated graphics chip, the use of PowerPlay 5.0 power-saving technology, Mobility Radeon X600, ATI also introduced the latest development of the Vari-Bright technology, the function can be graphics directly control the brightness of the display of notebook computers, further power saving. However, it is important to note that, X600 does not support X300 HyperMemory technology applications, so there is support for the Mobility the Radeon X600SE score 3Dmrak03 under can reach 3,000.
Of course, X600 is not the only early in 2005, ATI released the Mobility Radeon X700, Radeon X800 architecture, engineering, code-named the M26 core architecture as RV410, full support for the DX 9.0b. For the first time using the TSMC 0.11μm manufacturing process, can greatly reduce the power consumption of the chip running at full speed, but also makes the X700 graphics chip, the number of transistors to 120 million, surpassing the 9800 level, with eight 3D pipelines, six vertex shaders, pixel fill rate has reached amazing of the 2.8GPixel / s, higher than before the introduction of as much as 75% of the Mobility Radeon X600. It is worth mentioning, X700 used to dynamically change the PCI Express Lanes to connect a number of Dynamic Lane Count Switching (DLCS) technology, in order to better power. Technology can DLCS turned to battery-powered notebook computer power supply from the power adapter, the PCI Express x 16 interface changes to the PCI Express × 4, × 2, and even × 1, to save battery power. The ATi DLCS technology can save up to 30% of electricity. In addition, the Mobility Radeon X700 graphics chip also supports ATi mobile Upgrade the AXIOM.
The absence of the Low-K technology, the Mobility Radeon X700 core frequency is only 350MHz, expensive GDDR3 However, memory is used to support 64MB to 128MB, and frequencies up to 700MHz. Use technology of Smoothvision, Smartshader, the actual performance almost twice that of the Mobility Radeon X600 also supports ATi's PowerPlay 5.0 power-saving technology. Overall with the 9800 tournament, for a time, X700 but myself the situation.
PCI-E was introduced by Intel, but we are here to introduce products using AMD chips. In other words, PCI-E is good stuff, How could Intel alone the United States? That is the island's strong Acer Ferrari 4002WLMi configured AMD Turion 64 ML-30 (1.6G) / 512M/DDR333/5400 turn / 80G HDD / Built-in DVD-SuperMulit/15.4 inch display / WXGA / independent 128M ATI Mobility Radeon X700 graphics card / 56K V.92 / built-in 10-100-1000M NICs / 802.11b / g Wireless LAN, IrDA infrared mode group Bluetooch Bluetooth module / about 2.86Kg/Windows XP HOME / 1 year international warranty.
X600 is the transformation of ATI from X300. Using the X600 notebook is not much, because its performance with 9700 or less, manufacturers usually push 9700;, X700 is basically a synonym for notebook graphics performance, many manufacturers either do not push alone significantly notebook, to push, push X700 the. The X700 is that ATI really understand the meaning of the PCI-E? Came of age. Perhaps this is why ATI at the launch of the X800 also introduces the reasons of the lower performance X700. Why should highlight DLCS? User performance to be higher or lower temperature? ^ _ ^ In addition, Acer's Ferrari series of books is quite distinctive, sold in Europe, particularly fire, this Ferrari 4000 is AMD and ATI dual A classic hand in hand. ? How with the double "B" so much like it? Looked at the Ferrari logo, Smart was saliva in ~~ ~~ Oh. The face of the price of more than 16K, but unfortunately not m!
6.Mobility Radeon X800 is strong enough to finished machine
It can be said, X800 is forced out. Nvidia is the end of 2004, released a mobile chip Geforce GO 6800, and the performance goes well beyond the Mobility the Radeon 9800 ATI was the strongest performance. Last resort, ATI introduced the Mobility Radeon X800 to deal with, and even skipped the original R400 directly to R420, the absence of any shrink of the R420 core of the X800, the X800 in performance for the first time beyond the desktop PC graphics chips. X800 project, code-named M28, released earlier than the Mobility Radeon X700, so there is no use of the latest 0.11μm manufacturing process, but using the Low-K technology, reduce heat, the number of transistors 1.6 of the ATI Mobility graphics chip peak million! core frequency up to 400MHz, and chief of the 256bit memory frequency up to 800MHz GDDR-3, higher than the Mobility Radeon X700 nearly doubled in the actual performance, the same support for the fifth generation of ATi Powerplay power management technology. Finally, there is X800PRO/X800XT, bringing the total to 16 in addition to increasing the 4 3D rendering pipeline, but also to improve the graphics core and memory frequency, including the flagship X800XT core frequency and memory frequency of both reach 480MHz/1100MHz a new high.
The X800 is too strong, and powerful on the market almost no assembly of finished machine. Original on the CES 2005, AIT exhibited two X800 notebook, even in 17-inch screen can also be smooth running FarCry. Engineering prototype D700W not even be able to use the Sonoma platform, desktop barebones, no wonder that to achieve a weight of more than 5Kg. It uses Intel Pentium4 Prescott 3.2GHz, the desktop version of the Intel 915P chipset, DDR 1G (512M +512 M to build dual-channel platforms) memory, 15.4 "UWXAG (1680x1050) wide high score screen, 256M the PCI-E architecture ATI MOBILITY RADEON X800 card, 80GB5400 rpm SATA hard drive, dual-mode DVD burner, 6600mAh battery. overall configuration is worse than the desktop: 1024 3DMark2001 detected under the resolution of 18919! the 3DMark2005 also reach staggering 4 298, Half live II up to 55.27 fps. MCJ November 24, the GW760 use a Pentium M 2GHz processor, 2GB memory, resolution up to 1,680 × 1,050 17-inch widescreen display, the graphics card is used MOBILITY RADEON X800XT PCI Express x16 interface, memory reach 256MB , 100GB hard drive, Intel 915PM Express chipset, the performance can be described as the mighty foreign price of RMB that is more than ¥ 16K.
What is strong enough to be added? X800 who can get to know, now you can buy books using this card? Here to explain the meaning of X in the X800. "X" has two meanings: first, "X" from the English "extreme", with representatives of unparalleled performance; "X" pronunciation is a bit like the Roman numeral "10", it is succeed Prior to the ATI graphics chip geometric series Department: RADEON 9xxx, after all, if the new generation of graphics cards named "Radeon10800" if a little awkward. Technically, the R420 core seems to be just R3XX the improvement and optimization. In contrast, NVIDIA's NV40 support new DirectX9.0C Shader 3.0 technology, the R420 is just the original R3XX on the basis of improved Vertex shader, Pixel shader and FSAA function. R420 only support the new feature is the new Normal Map compression technology 3Dc technology, the biggest innovation is the 4X4 pixel pipelines portfolio. So I said a concern, perhaps the X800 mortality? Because new, better, the R520, RV530 already appeared. Below we will talk about. Perhaps unfounded, who knows?
7. The Mobility Radeon X1600/X1800: ATI's new generation of angels?
The data show that the ATI upcoming latest mobile graphics Radeon X1600, compared with the desktop version, using 90-nanometer production process, power control will also make quite satisfied. It will have 12 pixel pipelines and four vertex shader units, and based on the RV530 graphics core, support 128bit memory officially provide support for Shader Model 3.0. Will include the Radeon X1600 XT Crossfire version of the Radeon X1600 XT version and the version of the Radeon X1600 Pro. ATI's R520, RV530 and RV515, the RV530 using mid-range core, I am afraid that users are most concerned about the product: cheap, new features and the standard X800 12 pipeline:
The X1600 uses a new design, and enable the first generation of ATI's 90nm process production, integrates 157 million transistors, with 12 pixel pipelines and 5 vertex Shader units, 4 texture units, Render Back Ends, 4 and 8 Z Compare unit and single-cycle, the highest executive ability of the 128 thread. This is more than the original ATI RV410 for mid-range market, the 8-pixel pipeline 4. Heritage of many of the design of the R520, so compared to the original core is really advanced a lot, enable a new Shader architecture, providing support for SM 3.0, using a new memory controller structure, higher image quality (support HDR, with the 128FP computing capacity, to provide a new anti-aliasing), support AVIVO platform. A the Render Back End (RBE) is worth mentioning, which is similar to the NVIDIA display card ROP (Raster Operation Processor raster operations processors) function, and multi-sampling anti-aliasing can be achieved when the FP16 operation, that is, said RV530 AA sampling or anti-aliasing can also be achieved in the implementation of such operations such as HDR. This is due to any NVIDIA graphics card. Although the in RBE number, the RV530 4, more than 16 of the R520, it is little too much! Moreover, the generation RV410 has a complete 8 RBE units and 8 texture units.
That is the problem, obviously, if the RV530 RBE and texture unit, will certainly affect the current X800. X1600 core RV530 12 pipeline for the GeForce 6600/6600GT of 8 pipeline, which unfortunately hurt with 12 pipe X800 innocent. Look at the competitive situation, ATI useful may depend on NVIDIA's action in R4XX core reservoir released an enhanced version of RV530, for example, the RBE and texture units raised to 12, while the efficiency to solve the updating problem. Desktop graphics, the X800 mobile version of inventory how much? Not a lot of it?, X1600 will advance comprehensive alternative to the X800 in the mobile space? After all, from a cost point of view, X800 in any case will not exceed the X1600's. After all, the X800 X1600 is by design revolution to improve performance by upgrading frequency performance gains at a glance which one is better. Overall, the life of the X800 in the mobile space probably will not also, at least not more than the X600.
Integrated X300 ATI integrated solutions 8. Mobility Radeon XPress200
Since ATi released the Radeon Xpress 200 series chipset, it will become the industry's fastest graphics integration solutions. The Radeon Xpress 200 series integrated Radeon X300 graphics core, full DirectX 9.0 support, not only to meet the day-to-day multimedia applications and 3D games, also has great graphics performance HYPERMEMORY technology. The Radeon Xpress 200 series motherboard chip for RS400 and RS480 two groups, both basic specifications, only the former supports the Intel platform, which supports the AMD platform. Use XPress200 basically see it as the X300 graphics books. Of course, he can not really reach the level of the X300, the X300 also sell out? In the 3Dmark01 test, integrated X300 graphics score barely close to the ATI9200 graphics; 3Dmark03 test, the integrated X300 graphics card to play a strong performance , the score is almost twice the ATI9200 graphics (almost 2 times) 915GM integrated graphics.
To be mentioned here is the famous HP ze2202ap, you say that this HP is really lovely, especially like to operate a low-end books. is one of ze2202ap, using the AMD mobile Sempron 2800 +, ATI xpress200 chip group integrated X300se graphics, 256MB of DDR memory, 40G hard drive, combo drive, built-in 802.11 b / g Wireless LAN and 15-inch TFT-XGA display . This selling the HP ze2202ap in the Beijing Gome price of 5700 yuan, cheap bar. However, if you know in a foreign country, HP and Wal-Mart teamed up to launch a price of only $ 378 (about 3288 yuan), HP ze2203wm do you think? Both notebook configuration and mold are the same, only difference is that ze2203wm than ze2202ap less a USB interface and an N-card reader. Foreigners but to grab the notebook hit the frame. Huh, huh.
Integrated chip is sufficient for many people use the notebook, notebook manufacturers obviously can not ignore this, it is wise Intel be able to replace the ATI become the new dominant reason. Remedy the situation now is not too late, XPress200's success is an example. However, I worry about the Intel integrated graphics capabilities, but a small portion of a lot of the ATI, nVidia and do may a disk performance on the BUG may be able to destroy them on the integration of all results.

The nine bad habits of Laptop computers use!

Did you know? In fact, when using a laptop computer, we will be more or less there are some bad habits, most likely because these small details give our laptops damaging unintended consequences. Do not wait for trouble was a rude awakening, take preventive measures, let us look at all those bad habits should be corrected.
Fingers away from the screen
See the contents displayed on the screen, inevitably, there is excited about the picture, this time must remember, in your excitement, it is best not to let your fingers touch the screen.
Notebook computer screen coated with a layer of special material, it can screen more clearly. There may be some friends will say, we do not feel check it out, in fact, this layer of material only a few microns. If the LCD, pointing with a finger or other hard objects for a long time will cause this layer of material damage, which greatly shorten the life of the screen. We can see some scratches, some second-hand laptop LCD panel are pointing Jiangshan masterpiece. Start the laptop, we can see that the colors displayed by these scratches premises is far from full, soft and elsewhere.
The keyboard - take off your watch
Many of my friends using a laptop computer will ignore a problem, is part of the wrist below for the laptop keyboard wrist drag wear. In particular, with a metal strap watch or bracelet, wear and tear of the notebook computer is even more serious, long time, in a leave indelible marks on a laptop!
Although this performance for notebook computers does not have any effect, but it greatly reduced the appearance of the notebook computer, is actually very simple, when you're typing the watch off to, it is completely avoidable.
Shuihuowuqing - Do not smoking drinking
For many male users in one hand and folder smoke in one hand and the mouse is very often the action from time to time will be the folder smoke hand to knock a few keyboard. In fact, such an approach is not correct, will most likely soot fell into the cracks of the keyboard, what is more, not yet extinguished cigarette butts dropped on the keyboard and the keyboard is ruined, is not never happened, so using a laptop, try not to smoke.
Put a glass of water next to the laptop, is also a very common thing, but your attention is best cups placed away from the notebook, or accidentally knocked the glass, spilled on the keyboard, the problem may big! Burned the main version is not sensational, because the majority of laptop keyboards are not waterproof, if the water is more than enough, to penetrate to a laptop computer inside, too late to cry!
If you are the stubborn side of tea to drink coffee with the laptop, then, we also recommend that you it is best to put the cup on to the lower than a laptop position, or the cup on the left side of the notebook computer, more than 10cm away from the notebook computer distance. The relative frequency of sliding the mouse to the right hand, left hand knocked over a cup of probability will be smaller, 10cm distance can effectively prevent the full glass of water spilled on the laptop.
On Journey- carefully open the notebook computer
Notebook computers to bring carry portable use, but not when used. Unless you are using a kind of "three" good performance notebook computers.
The invasion of sand for the notebook computer can also cause very serious damage, the gap of the keyboard, various types of interface when it is tainted dust, clean up is a very troublesome thing.
The unexpected fall for the hard disk damage may be irreparable. For notebook computers with hard disk protection system like IBM and the like, maybe the problem is not great, but the majority of notebook computers do not possess such a device, even on a bumpy car, open the notebook computer may also be laptop computer damage, so above the road, do not use your laptop regardless of the occasion. In addition, we should try to use strong, good quality laptop bag, even when accidentally dropped your laptop computer last line of defense.
CD-ROM drive - Best not to use
In contrast, the drive is relatively easy to aging parts, laptop computers, CD-ROM drive is mostly no exception. The laptop computer's CD-ROM is a multi-specialty products, damaged, replacement is trouble, so to cherish with.
With a laptop to watch VCD, or listen to music is not a good habit, replacement laptop drive enough money to buy a senior VCD players or portable CD player to listen to, why should a laptop computer point of view CD? Say on the laptop screen and sound effects I am afraid that is also very flat.
Attention to the heat - to put an end to the bed use
Some of my friends like to use a laptop on the bed. In fact, this is a very good habit. Soft surface make the body sink, cover the vents, seriously affect the cooling of notebook computers, ranging from laptop computers to restart, while the notebook computer crashes and even expired.

Is not completely in bed using a laptop on the market today, there have been a dedicated laptop desk used in bed, the price is a bargain, as long as tens of dollars, it is quite convenient.
The battle of the battery - do not have to pay attention to
Mobile applications has been an important distinction for laptop and desktop PC, excellent mobile applications, much depends on the battery life. Many of my friends do not know the correct battery to use, with a period of time, the battery capacity is greatly reduced compared with the original can only maintain a relatively short period of time.

Notebook computer multi-use lithium batteries, although the lithium battery has no memory, but also the inevitable aging. If you use battery-powered, then it is best to use only the remaining 5% of capacity. Premature or excessive discharge, and will accelerate the aging of the battery. To know any of them as long as the battery pack is a battery aging, which means that the entire battery scrap. When the feeling of decline in battery performance can be several times the battery fully charge and discharge process, make the battery performance has been effectively restored.
AC power is available in AC, as far as possible. Some of my friends simply remove the battery to the practice, not entirely on if you encounter a sudden power failure, they think of the benefits of the battery.
If connected to an external power supply for the long-term use of computers, the correct way every one to two weeks for a battery discharge, notebook computer only battery-powered, no external power until the battery remaining less than 10% charge. The right way to maintain the battery, usually battery can use for about three years.
Car owners - Do not use laptop on the car
Now many car owners like to put the laptop on the car trunk, in fact, incorrect. First, the trunk of the car is not safe against the trunk of a car theft also happened quite frequently, If you are unfortunate enough to become the target of the thieves, that the consequences from not saying much.
The most important thing is that if it is in the summer, we will experience is the one to open the door after a heat wave hit. Car sunlight can reach temperatures above 70 degrees, the temperature inside the car trunk will not be low where to go, such a temperature, place the notebook computer, certainly not knowingly choose.
Holding laptop sleep - disorder of your habits
Finally, this is a truth! Two days ago to see a colleague lying asleep on a laptop because of overwork, Jun accountable accordingly, holding the notebook computer to sleep habits. Could that be a laptop as a pillow?

If drooling ...
In fact, in our daily life, everyone inevitably will be a little less correct method of using a laptop computer. Treat your laptop, to correct incorrect habits, the notebook computer to be able to better service for us.

Resolve four laptop anti-theft equipment advantages and disadvantages - anti-theft lock

For students, office users, the laptop usually used in the bedroom, office and other public places, and people coming and going due to the use of premises, notebook size, compact and convenient, believe it can easily be lost. In addition, some travel, travel friends, train, car or stay in the guesthouse hotel, due to the neglect of the notebook security and let the laptop is lost, convenience so that we have to choose a notebook, but it also brings security risks for some special users, and sometimes loss of more than a laptop, data loss or theft is a very serious matter, and ultimately bring significant economic losses, and therefore must be of great importance to the laptop anti-theft measures, due to the different anti-theft technology, making notebook anti-theft measures differ for notebook users, the laptop anti-theft technology really work? Security, security level and how much?
laptop anti-theft locks: cheap, easy to use, but not reliable
Working people go out every day will be locked the door, car owners the same need to lock the car in the parking, because we are worried that the thieves sneaked into the home and stole things, or forcibly stole the car, notebook compact, convenient and easy to carry, placed in the bedroom, office or train luggage rack, a moment's inattention may also encounter the risk of stolen, in order to prevent the laptop is stolen, the first anti-theft technology is anti-theft lock, which is home door locks almost no difference to our daily view from a laptop anti-theft technology, anti-theft lock is still the most common security, security, and occasions such as our product exhibition, a variety of activities, usually you can see a wire notebook is locked in the booth in order to prevent thieves pilfering.

The notebook locked in the desk
From the functional point of view, the anti-theft lock notebooks rely on an anti-theft cable and lock cylinder fixed, anti-theft wire galvanized steel cables made of high strength materials, the lock cylinder with two sizes, a key anti-theft lock, it is ordinary lock for locking bicycles and motorcycles, and lock the notebook and unlock the door using a key; another password security lock, which is similar to the lock on the trunk of the password, you can set a good password unlock, to avoid the use of a key or keys lost trouble. With a lock slot on the notebook, use anti-theft lock cable around on the tables and chairs or other fixed items, and then anti-theft lock into a notebook lock slot, notebook lock, so that you can effectively prevent the notebook is Pirates.

Clean-up notebooks fan and fan refueling

I have a ThinkPad T43 , using the screen suddenly appeared "FAN error" prompt, and then automatically shut down, and repeatedly tried several are. Prompt the point of view, is the laptop cooling fan is a problem. From the external clean up the fan and radiator outlet of the dust, but the fault remains. Struck with bamboo fan leaves, and found that fan leaf rotation is not flexible, resistance, and the description of the fault really lies in the fan. We know that the books of the cooling system is mainly composed of heat sink, heat pipe and fan. Books fan rotation is not flexible, the speed decreases, the cooling capacity of the cooling components will drop, along with increase in CPU and GPU temperature, when the temperature rises to a certain extent, BIOS or CPU will be issued a warning prompt and automatically shut down, some The books will be a blue screen or crash.
fan refueling
fan refueling
From the outside can not be cleaned the fan had to open books, remove the cooling components, once again clean up the fan, but still did not improve, indicating that the problem is only open fan in the fan on the internal shaft to deal with. T43 fan is direct pressure on the heat sink, no screws to open the fan, you must pry open the four fixed points of the fan aluminum case.
Clean-up notebooks fan
Clean-up notebooks fan
The demolition must be careful not to damage the heat pipe and heat sink. Otherwise, the loss. The specific method is: use one word to head a small screwdriver, slowly into the gap between the four fixed points next to the heat sink and fan aluminum case in turn leveraging the fan and heat sink separation, and then gently pull out the fan leaves . If you can not pull it out, must not pull hard fan shaft sludge seal, required 99% alcohol soaked fans will be able to remove, usually after a dozen hours.

Nine skills upgrading a notebook running speed of 100%

Laptop using XP, the operating speed as time goes by more and more slowly, and some friends may think to reinstall the system, but after the reinstall, so many applications have to reinstall, how enhance the speed of XP, do not install the system under the premise? As long as you are safe according to the following nine aspects of the operation, I believe that your XP will re-run at high speed.
1, accelerate the speed of the switch machine shutdown in Windows XP, the system will send a message to run the program and the remote server, and tell them to shut down and wait for receiving the response from the system began to shut down. Speed ​​up boot speed can be set to automatically end task, first find HKEY_CURRENT_USERControl PanelDesktop, the key set of AutoEndTasks 1; then branch a "HungAppTimeout" its value to "4000 (or less) 50000; Finally, find the HKEY_LOCAL_MACHINE / System / CurrentControlSet / Control Again WaitToKillServiceTimeout is set to "4000"; through this set off significantly faster than a lot of speed.
2, to improve broadband speed Professional Edition of Windows XP default to retain 20% of the bandwidth, in fact, for our individual users are not that useful. In particular, let it idle might as well take full advantage of. "Start → Run, type gpedit.msc, open the Group Policy Editor. Find the "Computer Configuration → Administrative Templates → Network → QoS Packet Scheduler" and select the right "to limit reserved bandwidth" and select "Properties" to open restrictions may retain the bandwidth of the Properties dialog box, select "Enable" and the original 20 "to" 0 ", so that the release of the reserved bandwidth.
3, optimization of the Network Neighborhood of Windows XP Network Places in the use of the system will search the shared directories and can be used as a network to share printers and scheduled tasks, and network-related scheduled tasks, then show up, so obviously slow the speed a lot. These features are not much used, you can remove it. In the registry editor find HKEY_LOCAL_MACHINE / SOfeware / microsoft / Windows / Current Version / Explore / RemoteComputer / NameSpace, remove their (printer) and {D6277990-4C6A-11CF8D87-00AA0060F5BF} (scheduled tasks), restart the computer, another visit to the My Network Places, you will find a lot faster.
4, faster boot speed up Windows XP startup speed. Can modify the registry to achieve their goals in the registry editor, locate HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlSet / Control / Session Manager / Memory Management / PrefetchParameters, on the right to find EnablePrefetcher primary key, its default value of 3 to 1, so scroll rolling time will be reduced;
5, sometimes stops responding A program is automatically shut down, XP will prompt you for a certain program stops responding, pain, by modifying the registry, we can let itself off in the HKEY_CURRENT_USER / Control Panel / Desktop in character and health value is the value of AutoEndTasks data changes as a re-write-off or start to.
6, to speed up menu display speed in order to speed up menu display, we can be set in accordance with the following methods: we can HKEY_CURRENT_USERControl PanelDesktop be found under "MenuShowDelay" primary key, its value to "0" can reach speed up menu display effect.
7, DLL files, clear the memory will not be used in the registry HKKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / Windows / CurrentVersion increase in Explorer an item AlwaysUnloadDLL, the default value of 1. Note: If the default value set to 0 to disable this feature.
8, To speed up the pre-reading skills to improve the boot speed Windows XP pre-read settings can improve system speed, speed up boot speed. Modify the further utilization of the CPU efficiency of the following methods: HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlSet / ControlS / essionManager / MemoryManagement], in PrefetchParameters the right side of the window, the following changes will EnablePrefetcher numerical data, such as the use of the above suggestions in the PIII 800MHz CPU the value changed to 4 or 5, it is recommended to retain the numerical data to the default value 3.
9, to reduce the start load the project application during installation will be given a free hand to add to the system startup group, every time you start the system will automatically run, which not only extended the start-up time, and start after the completion of system resources have been consumed! To start the System Configuration Utility ", listed in the" start of the project and source loaded at boot time, carefully to see if you need it to automatically load, otherwise clear the check box in front of the project, the project, the less loaded The startup speed is naturally the sooner. The need to restart before taking effect.

Intel once again hit back at AMD

June 30, Intel Centrino Duo mobile technology media communication at the meeting, Intel from four perspectives on the technical aspects of comprehensive fight back the AMD. This is Intel's 27 competitors for the first time since the contrast of yet another battle.
amd_vs_intel
Competition power - which one is better
Processor power consumption has been an important aspect to measure the notebook computer, because it is decided the notebook to use an important aspect of time, heat and other important indicators. Intel platform application innovation alliance manager Zhao said on this issue: power consumption, we work hard, the generation of products usually cost hundreds of millions of dollars to verify, for example, our upcoming Core 2 generation, the introduction of the latest enhanced C4, it not only can any one of the core in the dual-core C4 Sleep is more important is that it can cache the data temporary inch in memory, so that the processor to achieve a deeper degree of dormancy. In terms of products, a competitor's product the lowest power consumption of 31W, Intel also has a 10W-15W product, only with passive cooling, power is not a problem for Intel.
amd_vs_intel
The memory controller decided to upgrade the difficulty
For competitors in the new processor, integrated memory controller, Zhao responded. He said: "For the memory controller, not what we do not have this technology, but we made after weighing, and finally decided not to introduce for notebook computers, is not a separate processor to determine its performance memory is extremely important and integrated memory controller, the biggest problem is to affect the memory upgrade when changes in memory technology, and not the old CPU's memory controller, memory controller on the memory requirements are too strict. so that the processor is difficult to keep up with the pace of memory updates. will inevitably lead to the difficulties of memory upgrade. "
intel_vs_amdThin showdown - who slimmer
Another indicator of the notebook - thin, Zhao said: "For Intel, the slim also not a problem. 10W-15W ultra-low power processor with passive cooling way, thereby reducing the fan thickness and volume. makes the laptop thinner and smaller. like a product of Apple, just a bit thicker than an ordinary magazine. which also competitors can not do. "
65-nanometer process collision -64 bit technology
Zhao said, referring to 64 products: 64-bit technology is not only to upgrade a processor will be able to solve the problem in terms of hardware, memory, and the bus has not yet developed to the 64, will be largely 64 The play-bit processors. software, although Microsoft has launched a 64-bit operating systems, application software has not been introduced 64 products, which limits the play of the processor from the other side. Therefore, in the current case, we will not further introduced 64 products, we feel that the main push of the 64 technology has yet to be timing. "
Zhao said: "Core in a generation we used the 65nm manufacturing process, can also prove that the application has been fully mature 65nm the opponent has not yet been introduced the 65nm products. Intel's 65nm process technology, production capacity has more than 90nm, and will launch in the next year close to 2008, when the product using a 45nm manufacturing process. "
Conclusion:
Competition means the price war and the war are indispensable to modern industry, the two processor manufacturers reflect the market price war in the end who wins the technology war will have to see. Who cares! Anyway, we got affordable.

Laptop Keyboard- The world's first chocolate keyboard notebook

Which to the world's first with a chocolate keyboard notebook is it? Many of the Friends may think the Apple notebook, it is not, the world's first chocolate keyboard appear in 2004 Release Sony Vaio X505.
chocolate keyboard

Caused by graphics card fault causes and solutions

Comments: The graphics card failure caused by reasons and solutions
The cause is usually caused by graphics card failures are the following:
Poor contact. Poor contact due to the AGP slot on the graphics card and motherboard, general swappable graphics card or clean the card cheat site troubleshooting.
Driver failure. Into the system graphics display is not normal, generally, just re-install the drivers you can troubleshoot the driver is not installed correctly or driver error caused.
Graphics fault monitor maintenance
Overclocking failure. Sometimes the use of overclocking software graphics card overclocking the graphics card does not work, then need to use overclocking software shortcuts revert to the default graphics card working state.
Graphics component failure. Due to the failure of the components of the graphics card itself, only to be replaced or contact a professional maintenance staff for repair.
The following describes the common graphics troubleshooting instance.
1) graphics job insecurity
Fault phenomenon: the purchase of new graphics cards in the use of unstable, and often crash phenomenon.
Failure analysis and processing: graphics technology continues to progress makes new graphics listed, the new graphics card's power consumption is also increasing, if the graphics work can not be stable and sufficient current will cause the instability of graphics, resulting in crashes .
If the motherboard can be independent of the AGP bus power supply circuit, as far as possible to the graphics of the wires to the above. Some motherboards have the option to adjust the AGP voltage in the BIOS, you can try to appropriate to enhance the AGP voltage to enhance the stability of the AGP graphics card.
2) video card cooling caused by bad Huaping
Fault phenomenon: a computer in the course of normal use Huaping phenomenon.
Failure analysis and processing: Huaping phenomenon is due to graphics issues. Open the chassis, remove the graphics card, graphics card heat sink is very hot, the conjecture is likely to lead to graphics Huaping graphics chip temperature is too high. Then add a cooling fan for the graphics chip. Reboot after Huaping troubleshooting.

Laptop battery maintenance? Several Use major errors

Since the day Laptop computer was born, the debate about the laptop battery has never stopped, because the use of persistent notebook computer is a very important technical indicators, the capacity of the battery determines the important indicators of the notebook computer. In the end how to use the effect of in order to maximize the battery to extend battery life? Below, we list several for everyone we often vulnerable to misunderstanding:
First, The first time using the battery, the first three need to be charged 12 hours?
Doing so is completely unnecessary. Because now the laptop has improved power management circuits and charging management system, when the battery reached saturation, the control circuit will automatically switch to the off state, so long as full of on the line, not to say that you charge as long as you can use the longer the.
Second, in order to prevent the memory effect, we should run out of power before charging it?
Discharge the battery before each charge is not necessary, but it is harmful. Practice has proved that: the depth of discharge of the battery will be unnecessary to reduce the battery life, it is recommended that when the battery used in about 10% can be charged. Of course, when the battery is still more than 30% of electricity is best not to charge because the memory effect does exist.
Third, plug in the AC, the battery should be scored, in order to prevent repeated charge and discharge?
My advice to you is: No! Of course, you can take the natural discharge of the lithium-ion battery to refute my battery after the natural discharge, if the power access to repeated charge and discharge, reducing the battery life. And I give you "No" answer to this question, there are several reasons:
(1) the power control circuit of the notebook are designed this feature: When the battery reaches 90% (such as most of the HP models) or 95% will be charged by natural discharge to the time of this capacity to 2 thoughtful one months, when the battery is left unused for a month or so to fully charge and discharge in order to maintain the battery capacity, this time you should be concerned about is the battery should exercise the body instead of being idle again after charging.
(2) Even if the battery "unfortunate" is once again charging the loss will not be brought down much greater than long periods of inactivity caused by the battery power.
(3)Your data than your battery or your notebook are much more valuable, a sudden power failure will not only harm your laptop irreparable data is too late to regret.
Fourth, long-term preservation battery needs to be filled with electricity?
Read the following table: (percentage of saturation at the time the relative percentage of the initial value)
Storage temperature is 40% state of charge 100% state of charge
0 degrees 98% (a year later) 94% (one year)
25 degrees 96% (a year later) 80% (one year)
40 degrees 85% (a year later) 65% (one year)
60 degrees 75% (a year later) 60% (3)
Obviously, if you want long-term preservation of the battery, as far as possible on the dry and low temperature environment and remaining battery power at about 40% is ideal. Of course, each month is best to take the battery out once, both to ensure that the battery is a good state of preservation, but not so the battery is completely lost and damage the battery.
Fifth, use as much as possible to extend the use of laptop time?
(1) lower the screen brightness. LCD screen, but power-hungry, the decrease in brightness can effectively extend the use of time.
(2) Open SpeedStep and PowerPlay power-saving features. Notebook processors and graphics chips have a lower operating frequency and voltage to extend the use of time, open the appropriate option can greatly extend the battery usage time.
(3) hard disk and optical disk drive spin-down software: NERO DriveSpeed, PowerBooster software can reduce the speed of the optical drive, hard drive, can also effectively reduce the notebook's power.

How to Solution tht PC CD-ROM drive can't Pop-up out?

Not long ago, the company server, load the CD-ROM drive fails, still alive and put the disc after the copy of the finished disc inside the data, even when the push plate optical drive Pop-up do not come out after, and then only reluctantly to restart the computer, but the problem still, the last force to push the disk to pop up with a needle. CD-ROM shells do not come out is a common computer failures, in general may be the CD-ROM drive itself, or the internal shrapnel, some may be a small problem, the next editor will introduce the CD-ROM bomb under solution .
Restart the computer CD-ROM drive Pop-up out of the first attempts to try, because sometimes may drive inside the computer program error causes the shells do not, but according to the frequently re-start effect, in general, the computer for a very long period of time, part of the hardware has begun to age, we often encounter a bomb out of the computer drive, click the CD-ROM button to see the drive lights flash twice, only to hear a creaking sound, but the tray is the bomb does not come out more than a few CD stands occasionally still pop up, but always good times and bad, so we need to pay attention to under. Below we take a look at the CD-ROM bomb is not the solution!
To resolve the CD-ROM shells do not come out, we must first understand the reason of the CD-ROM bomb out, here are summarized as follows:
Scenario 1: CD-ROM drive to a warehouse key failure
When out in the CD-ROM drive on the panel positions key is pressed, the CD-ROM shells do not come out, but right-click the drive letter in "My Computer" select "pop-up" CD-ROM can the warehouse, which shows on the CD-ROM panel out key failure , the solution can try to remove the optical drive button focus on examination of whether there is poor contact, the solution can be, if you do not bother to, you can also ignore the pop-up drive, anyway, the computer can operate.
Scenario two: the optical drive out mechanical systems gear wear
CD-ROM out gear wear of mechanical systems, often in the press out of the warehouse key, can hear the CD-ROM issued by the warehouse when the "thump" sound, but the CD-ROM drive to play does not come out; this failure is due to the optical drive out gear wear caused the majority of computer CD-ROM and out of warehouses gear is made of plastic, long action, and plastic aging makes the gear premature wear, gear and gear with intermittent is too large will slip, resulting in a CD-ROM shells do not come out of the failure; solution proposed for maintenance, of course, if you are using a long proposal directly to a new, after all, CD-ROM is also cheap.
Scenario 3: CD-ROM drive mechanical failure
If the CD-ROM in the computer does not recognize the button no response to the above operation, first check the following connections, especially the power supply part, if not, then the CD-ROM itself, mechanical failure, maintenance can try to fix it myself (removable hard disk does not show how to do), good economic conditions to the proposed new.
CD-ROM bomb is not the solution:
Reasons described above, we can determine whether the problem belongs to which, and then corresponding to attempt to resolve the can, but for the novice friends can not ignore the CD-ROM there is an emergency eject function, a lot of time under the temporary use of, nor affect the drive to use.
CD-ROM shells do not - Do not forget to use the CD-ROM emergency eject holes
As we all know, the CD-ROM drive on the panel are designed to emergency out of position holes, once the drive fails eject position, you can use like a hard object such as a paper clip or toothpick into the emergency out of position holes (requires force), the optical drive tray will pop up a small part, and then hand to pull the tray; a lot of friends reflect that the drive did not find the emergency hole in a warehouse, in fact, need to drive bezel chassis to pull down, to see a real drive panel The drive panel should have a brand logo, you can put the optical drive bezel removed before the operation is relatively convenient.
Edit Summary: actually CD-ROM drive to play does not come out is due to the aging of the mechanical structure, through CD-ROM emergency out hole to force out the position in practice only a temporary solution, if the read ability of the computer drive read the disk speed is also very strong, we can consider the drive to send professional service points for the replacement of the wear gear, If you own a CD-ROM reading performance has been poor and used for many years, you should consider replacing the new CD-ROM, CD-ROM bomb I summarized above is not out causes and solutions to some reference on the face of such CD-ROM drive failures friend.

How to select the power supply?

An example to the AcBel IP Power
AcBel IP Power series can be said that the name brand cheap, but also all the rage, the purchase by the public.
But at the same time the power of the IP series also exposed some problems: the conversion rate is not high, excessive ripple output and poor cross-load. There is always let everyone ills
The AcBel been accustomed to 25 degrees calibration of output power, such as the IP470 is he the subject of the rated power is 420W, but AcBel is standard at 25 degrees,
We all know that the hot weather, a lot of people at home at room temperature more than 25 degrees, 35-40 degrees issued by the temperature even on the machine, power is a very common thing
To 35-40 degrees, IP470 rated power output is not the same, 420W should be discounted at this time is estimated only up to 300W of power to use.
Wow! ! There is such a statement? Yes, the power is so complex, various manufacturers have the manufacturers standard Chennai its Ho?
That being said, the IP470 whether can not be used? Definitely not! IP470 in the ordinary players in the eyes it is a high-end (of course, in the eyes of a small number of the best players this is the rubbish one)
But you do not see the city to sell the city's computer basically Han stuff, and then take a look inside the low-end brand of Han stuff? Then look back at the IP470 whether ordinary people in the high-end.
This power professionals to get into the test room into incubators, access load source, oscilloscope, casual look also know that the grade is poor.
Is indeed poor, and this is recognized.
However, we may not know, professional equipment even if it was so bad, but we use them how to feel it is relatively less problems?
Single power supply test so bad, is not equal to the entire platform testing so bad, because the hardware such as motherboards and graphics cards have their own independent power supply system, administered by the power output ripple less than satisfactory,
But through its own capacitor or an independent power supply system will convert and adjust their work to maintain normal. Some of the hard drive design also leave room for much sensitive to the voltage a little fluctuation of the point of inevitable accident.
The power supply is a complicated topic, toss the industry for so long are not fully mature program, basically the program available in the market is not the shortcomings in this regard is defective in that regard, sometimes the manufacturer is feeling the stones.
So I chose the power to choose some with the entire platform can be enough, no need to be too afraid, the computer is a set of equipment, not a single power supply in the battle, after all, there are other hardware circuit design for your checks to those XX capacitor the XX circuits where the use?

Common failure analysis of the notebook hard drive

Boot failure
In the process of the use of computers, we are likely to encounter the computer does not start. Cause system boot failure for many reasons, many of which are related with the hard disk. Under normal circumstances, when a hard disk failure, BIOS will give some English message. The motherboard of different manufacturers or different versions of the BIOS, the given message may be some differences, but basically similar. Here we use the more common of the Award BIOS, for example, to explore how to use the tips given information to determine and deal with the failure of the hard disk can not be started.
1.Hard disk controller failure (hard drive controller failure). This is one of the most common error, when this happens, should carefully check the data cable connection plug is loose, the connection is correct or the hard disk parameters are set correctly.
2.Date error (data error). When this occurs, the data read from the hard disk there is irreparable errors or bad sectors on the disk there. You can try to start the disk scanner to scan and correct sector of the logical errors, bad sectors are physical bad sectors, you need to use specialized tools to try to fix.
3.No boot sector on hard disk drive (hard disk boot sector). This may be on the hard disk boot sector is damaged, because of the hard disk boot sector is infected with a virus. Encountered in this case must be the latest version of antivirus software completely killing the virus present in the system, then, with a boot sector recovery features of the software such as KV3000, etc., try to restore the boot record. If you use a WinXP system, you can start the Recovery Console and call FIXMBR command to restore the master boot sector.
4.Reset Failed (hard reset failed), Fatal the Error Bad Hard Disk (hard disk fatal error), DD Not Detected (detected hard drive) and HDD Control Error (hard disk control error). When any prompts appear above, are generally hard to control circuit boards, hard disk interface circuit on the motherboard or the mechanical parts of the disk within a fault occurs, this situation can only professionals to overhaul the corresponding control circuit or a direct replacement hard disk.
Bad sectors failure
Through the above study, A King on the hard disk boot failure solution to understand, the next A King, of course, want to know how to deal with hard drives that have bad sectors. Teacher for A King tell us about the failures and the maintenance of the logical bad sectors and physical bad sectors. Lecturing before the teacher to remind A King must be careful to carefully do the work.
The logical bad sectors
Logical bad sectors and is prone to a daily use of the computer's hard drive failure, logical bad sectors in fact the disk tracks above the parity information (ECC) and track data and servo information does not match. The main reason for this failure is usually because of some procedural error operation, or harbinger of magnetic media sector there began to appear unstable phenomenon. Logical bad sectors in general computer use, file access error or do hard disk cloning to reach the error site, due to pop-up error message window and can not continue. Eliminate this logical bad sectors are relatively simple, a lot of special software such as: DM, Norton DISK DOCTOR can do, but the most commonly used "disk scan" feature that comes with Windows. FATl6 or FAT32 partition, you can use Scandisk in DOS real mode scan disk, system logic error sectors marked out in the future will avoid these sectors during the access operation. The use of these software is relatively simple and is also described here also, however explained.
However, if the NTFS partition and install Windows XP system, it does not have the Scandisk this tool, it can only use the Chkdsk tool. Chkdsk tool used by the file system, create and display a status report of the disk. In addition Chkdsk can also lists and corrects errors on the disk. But without any parameters, chkdsk will only display the status of the current drive disk, and not to correct any errors, to correct the error, you must include the / f switch.
Physical bad sectors
The hard disk physical bad sectors are more common hard drive failure. In fact, it is because the shocks, scratches and other "hard" because the lead - some sectors of the magnetic media has lost the ability of magnetic memory. Under normal circumstances, this damage was too much trouble to repair. Because, in the track list of the internal hard drive, this sector is marked as normal, while the bad sectors is also a physical existence. Therefore, it can not scan, format, low grid or activate the sector to be eliminated this sector must be added to the reserved area set up inside the drive, these tracks tell disk can not be used to hard disk visible within the control system to eliminate the bad sectors. Of course, this need to use some special software, repair some difficulties for the average user.
However, some hard drive manufacturers will provide the original software tools, such as the IBM / Hitachi DFT and Western Digital Data LifeGuard Diagnostics, These original tools not only fast scanning speed, and to identify the accuracy rate is also high, able to deal with the more common types of hard disk physical bad fault. Inside the drive or the original software is more reliable, unless the original tools can not solve the problem, or do not recommend using third-party tools.
Relative to the above, this advanced hidden way, for those less demanding users, the "bad disk partition FBDISK and Disk Genius a combination of software, complete the bad sectors location made the task of partition hidden. Its specific operation is briefly described as follows:
First, download the software to copy it to a normal use of the computer's C root directory, then the hard disk physical bad sectors on that computer as the two hard drives attached. Then boot to DOS real mode, and run Disk Genius executable program Diskgen, then press "CTRL + ALT key combination, select" hard disk "menu under" hard disk 2. Then you can see 2 hard partitions. If we were to re-planning the hard drive, you can put all partitions are deleted, then save and exit.
Then run the FB Disk hard drive to be detected is selected press "Y" to begin scanning. If the hard disk is bad sectors, the FB Disk will automatically show in which sectors and tracks. After the scan is complete, it can be all bad sectors are listed here, and asks if you want written to the hard disk. If press "Y" will be automatically bad sectors hidden, press the Esc key to exit.
Then run again Diskgen, then you can see the FB Disk after disk bad sectors at present - kind of gray. By Diskgen slightly hidden partition of the physical bad sectors expanded. Finally, all these bad sectors hidden in a partition, repair work will come to a close.
Both software used in conjunction with FBDisk processing hard disk may have a lot of zone, but by the software itself up to four primary partition limit will lead to a hard disk utilization is not high consequences. Diskgen with a good solution to this problem.

Two techniques to rule out the camera does not recognize failure

1 Vimicro camera driver version currently on the market popular many, many users install uninstall the driver remains inside of junk files in the system registry, resulting in difficult to install in the back of the driver update process;

2, currently on the market there is a clone operating system, which integrates Vimicro old version with over a WHQL driver, when the users to install the camera to buy a new or updated driver, the camera does not work;

Methods, automatic uninstall method

Step one, click the Start menu, the corresponding drive Uninstall uninstall (possibly Uninstall the function has been damaged, you can uninstall by installing a new drive, the system will first uninstall the old drive out and also to achieve the objective.)

Step two, before installation of the new drive, select the executable file attachments correspond to the following:
FOR_XP_ME_98.EXE used to WindowsXP/ME/98
FOR_Win2K.EXE used for Windows2000
(Note: The tool requires the system default path is C drive to be effective, in WindowsME/98 operating system such as an error dialog box appears, indicating that the system is already clean, the tool does not harm the driver has been installed)

Step three, install the new driver

The second method to manually uninstall method

Step one, in My Computer - Tools - Folder Options - View in hidden files and folders select "select all files and folders, and then to C: Windowsinf folder will be all the OEM files (such as oem0. inf, oem0.pnf; oem1.inf, oem1.pnf ...) cut and transferred to another directory to save or manually delete the oem files of the camera.

Steps to complete the above steps, insert the USB camera, then the computer will find new hardware pop up and install the driver information, select Cancel, then right click on My Computer, select Properties in the pop-up system properties of the interface, enter System Properties - Hardware - Device Manager with an exclamation point PCCAMERA right-click the uninstall;

Step 3, unplug the camera, install a new drive.

For the above second phenomenon

Step one, clone operating system is the camera driver default stored in the C: WindowsDriverCamera301P file folders below, when you click on the new camera driver CD to install, not prompted already exists there is the camera driver and put this driver uninstall, please put this file folder to find and delete;

Step two, first install a new camera driver, plug in the camera to load the hardware installation is complete, restart your computer after normal use;

Step three, do not need to repeat the above two steps, click on the new disc to install the latest drivers, plug in the camera system detects new hardware and automatically complete the hard drive to load;

Step four, into the Device Manager, you can see the image processing equipment has been successfully installed, but when you open the "AMCAP" preview image will not be able to preview, black and white, black phenomenon;

Step five, the right mouse button on the image processing device VimicroUSBPCCamera (ZC0301PL) "Update Driver dialog box appears, select" install from a list or specific location

Step Six Select Next and select "Do not search", enter "install from a floppy disk interface.
Step seven: Click browse, the path to the drive CD-ROM directory, or the latest driver directory below usbvm31b.inf
Step eight: Always click "Next" to complete the driver installation.

WiFi produced electromagnetic radiation can damage sperm?

In the waiting hall, many men notebook computer shelf in the thigh for news;
The children of the Tablet PC networking game more and more ...
We seem to have become accustomed to the ubiquitous WiFi life.
However, scientists in the United States and Argentina, a study found that the electromagnetic radiation generated by the wireless network will damage the male sperm, the sperm placed in the notebook following opening of the wireless network, than in the same temperature, but the sperm away from the wireless signal by loss deeper.
WiFi produced by electromagnetic radiation can damage sperm?
In this latest study, researchers collected the age of 29 in the semen of men between 26-45 years old, and were placed below the laptop connect to a wireless network and away from the computer.
Then, the notebook computer for four hours online uploading and downloading information.
Sperm on the laptop computer following the end of the experiment, 25% no longer swim, and another 9% of the DNA damage.
Away from the computer's sperm, only 14% is no longer swimming, and only 3% of the DNA damage.
The findings were published in the journal of fertility and infertility.
From the United States and Argentina, scientists believe that the electromagnetic radiation generated by the wireless network will damage the male sperm. "Kangla Duo · Aifen Dano, Cordoba, Argentina, the person in charge of the Center for Reproductive Medicine, said:" Our data show that if the notebook connected wireless network in place near the male genitalia, may impair sperm quality. "
Some people think that the implications of this study is that cause infertility are pointing the finger of blame on the notebook computer before the computer-generated heat, while this confused zeroed in on the wireless network.
This scene is not unfamiliar: in cafes, coffee shops, people kept brush microblogging many men to the notebook frame; in the waiting hall, holding a tablet computer networking games for kids everywhere in the thigh;
Our lives, seems to have WiFi full coverage.
In fact, India has done related tests, Indian scientists studied 371 cases of man through the male infertility evaluation, the continued use of mobile phones and mobile phone every day uploading and downloading information, and found to carry mobile phones and their use of time and sperm rapid was negatively correlated to the proportion of the movement, while the sperm quickly reflected in the forward movement of sperm motility. However, because these research trials are the lack of large sample data set of the control group there are unreasonable, and therefore the study results, the industry there is no simple underground conclusive.
Infertile men caused by faster than women
Although the WiFi spermicide is still controversial, but an indisputable fact that sperm quality has decreased year by year.
The statistics of the American Urological Association figures show that nearly 1/6 of the American couple infertility, half the reason the man.
In China, the proportion of male infertility is also improving.
The infertility survey released last year, a Zhejiang Province, Zhejiang Province, infertility infertile couples accounted for 5 percent of the married couples of childbearing age, including a larger proportion of male factor.
Reproductive Medicine of the Red Cross Hospital, Hangzhou, Hangzhou City, the earliest sections of the infertility treatment, and Reproductive Medicine, Director of Ding Caifei work in the city Red Cross hospital for 20 years, one of her feelings, which a few years, the men did not the proportion of education in improving. Come to the treatment of infertility in infertile couples before 1/3 of infertility, infertility is caused by man, this proportion had risen to 1/2.
Some men are supposed to accompany my wife to see the doctor, the results of my wife to check everything is normal semen analysis in the advice of the doctor's husband, only to find pregnant not on the child in fact is a man here.
Do not take the laptop on his lap Internet
Open the Bluetooth cell phone on his hip pocket affect testicular
What reason has been shown to decreased sperm quality of men?
Clinical evidence that estrogen can affect sperm quality, environment and lifestyle will lead to elevated male estrogen.
Life to eat the high estrogen content of soy, honey and other foods, cosmetics contain estrogen, in the intake of estrogen, while the environment also has estrogen, has identified nearly 300 species that may affect sperm quality environmental hormone chemicals, these substances are in close contact with our daily life, such as plastic, disposable foam products, pesticides, feed and food additives, detergents, cosmetics, artificial synthetic hormones, pesticides, herbicides, they are widely exist in food, daily necessities, vegetables, offshore fish, grains, air, drinking water and textiles.
In addition, a number of other modern lifestyle will result in men, decreased sperm quality, such as exercise, smoking, alcoholism, sauna, wearing tight jeans. In addition, the the sedentary does not move will lead to the prostate hyperemia, or triggered the the problem of the prostatitis and other, of these will affect the sperm quality.
For notebook computers and fertility research and discussion, a more reasonable concern is that the temperature of the scrotum near. If a long time to place the laptop in lap, this phenomenon may easily occur. Sperm in the testes to produce mature in the epididymis, more than 32.5 ℃ temperature will affect the epithelial cells, affect sperm mature, leading to reduced fertility. If long-term exposure above 35 ℃, the thermal environment, the greater impact.
Electronic product radiation is indeed one of the factors that affect sperm quality, although the impact is not yet conclusive, but if we can avoid some of the bad use of, or is best to avoid. Such as laptop computers placed on the desktop, and, as far as possible, using a wired network.
Also has been reported that the phones emit radio frequency electromagnetic waves will pose a threat to the male reproductive system.
India has done the research, a group of 371 cases of men to participate in infertility testing results show that the use of mobile phones harmful to semen quality, sperm count, the survival rate of sperm motility and morphological normal sperm count decreased, leading to male infertility.
Many men accustomed to on the phone near the genitals in his hip pocket, and this habit should be changed, especially some of the men often using Bluetooth mobile phone on his hip pocket or do in the waist, the testicular cell phone radiofrequency exposure to more this standby mode on the hip pocket and affect testicular more intense.
