Huaping black laptop solution

If you encounter a black laptop Huaping phenomenon, how would you deal with? Will repair, I think JS will make a quick fortune, in fact, if you own a little bit of DIY knowledge to understand, then, the phenomenon of black notebook Huaping and is very easy to solve, I put the conventional solution to introduce to you:
A driver problem
As the laptop's graphics chip driver not written after the chip company to provide chip, driven problem to a laptop manufacturers to write, so there may be some compatibility issues. Meanwhile laptop drive of release time is very slow, generally six months or a one-year update. Solution when the first try to see if we can run other 3D program is also seen the video, blank screen, if the problem goes away can be considered to compatibility issues. At the same time, damaged or missing driver files, may lead to false crash when running graphics, video, black and other phenomena, to solve this problem just uninstall the old driver, you can reinstall the driver.
Second, third-party software
Open overclocking software, if the memory frequency than the first, the screen appears mapping error, the video is normal phenomenon, and can lead to serious crashes. Because working memory in the non-normal frequency, higher frequencies will make its work to become unstable, especially in the data is read and prone to error. At this point, we only need to reduce or respond to the default frequency.
Of course, the above mentioned investigation of our laptop Huaping failure in the most basic way, if after debugging the fault persists, we should turn from the hardware aspects of the. On my personal experience, the phenomenon occurs laptop Huaping are generally hardware problems, software problems in compatibility more.
Three, LCD signal cable connection is bad
This is the first step we check the hardware. Video, blank screen appears irregular, or tap and press the keyboard surface after the fault disappears, it is often due to LCD and interface signal line the result of poor contact. We just need to re-seated the corresponding interface problem can be eliminated.
Fourth, the oxidation reaction
This is because laptops generally in poor conditions or prone to long-term use after the results of treatment, we first remove the interface signal line LCD, wipe with a rubber finger joints, and the interface is stained with a small amount of water used alcohol cotton scrub, the purpose is to remove dirt or oxidation generated due to poor contact phenomena. After treatment, and then re-connected lines, you can check is plugged in tight.
Fifth, memory problems
As part of the notebook graphics memory with dynamic video memory technology (DVMT, Dynamic Video Memory Technology), the use of part of the memory allocation for graphics memory. In actual operation, the internal structure may be due to memory corruption, when this part as to select the memory, the chip and memory errors during the data exchange often, leading to the video, black, or even the phenomenon of death. When this happens, we can use substitution to replace the same size of memory to be checked. Of course, if the memory is integrated on the motherboard, we can only repair the.
Six capacitor problem
RAMDAC (Random Access Memory Digital-to-Analog Converter) and the filter capacitor is to determine the picture quality is good or bad video card are two important factors. The quality of the filter circuit and the capacitor quality is linked to each other, when the use of poor quality capacitors or reduced capacity due to characteristics of the capacitor itself, the emergence of the video, black screen phenomenon flattering. In the settlement, we can first use a multimeter to check out the capacitor in question, and then replaced with the same specifications, so the problem can be solved.
That are more than we can handle their own problems, through commissioning, replacing the method can be resolved (Note: This article does not mention the result of poor heat dissipation caused Huaping problems, we all know, the laptop graphics use low-power design , the temperature in the control well, and finished products tested at the factory, manufacturers will naturally heat problem thoughtful), but for those who can not fix the problem, such as: chip defects, integrated on the motherboard memory corruption and so on. Encounter these problems, we can only repair the laptop, the way to solve such problems is often to replace the entire motherboard, which is difficult to do our DIYer.
Although the laptop problems, we can give the business deal, but who want to improve their ability and knowledge of the DIYer is, to solve their own problems, to enhance their own capacity, which is undoubtedly more meaningful!
