How to deal with the problem of black screen of notebook flower screen

　　First, the problem of driving

Because the laptop driver is not a graphics chip company to write, chip companies in the provision of chips, the driver of the problem to the notebook computer manufacturers to write, so there may be a certain degree of compatibility problems. At the same time, notebook computer drive to release a very slow, generally six months or one year update. The first thing we can do is try to see if running other 3D programs also have the same flower screen, black screen, and if the problem disappears, it can be considered a compatibility issue. At the same time, the driver file is damaged or missing, may cause the graphics card to run a false panic, Huati, black screen and so on, to solve this problem simply uninstall the original driver, reinstall the driver can be.

　　Second, third party software

After the overclocking software is turned on, if the video memory frequency exceeds the head, the picture appears the mapping error, the flower screen phenomenon is very normal, when the serious will also cause the panic. Because video memory works at abnormally high frequencies, the higher frequencies only make the job unstable, especially when data is read and written. At this point, we just need to lower or restore the default frequency.

Of course, the above mentioned is that we are troubleshooting notebook computer screen fault most basic methods, if the debug failure is still, we should turn from the hardware aspect. On the author's personal experience, the phenomenon of notebook computer screen is generally a hardware problem, software problems in the compatibility of more.

　　Third, LCD signal line Contact bad

This is our first step in checking the hardware. Huati, black screen phenomenon irregular appearance, or after tapping and pressing the keyboard surface after the failure disappears, this is often due to the LCD signal line and interface caused by poor contact results. We just need to reseat the corresponding interface problem to eliminate.

　　Iv. oxidation reaction

Generally this is due to the laptop in the environment or long-term use of the result is easy to appear, when dealing with, we first LCD signal line interface out, with the eraser joint of the gold finger, and the interface is stained with a small amount of anhydrous alcohol cotton to scrub, The aim is to remove adverse contact phenomena caused by oxidation or contamination. After processing, and then the line back up, check whether the plug can be.

　　Five, memory problems

As a result of some notebook computer graphics card memory using dynamic video memory technology (that is, dvmt,dynamic Memory Technology), the use of part of the memory capacity for video card memory. In the actual operation process, possibly due to the internal structure of memory damage, when to select this part as video memory, the chip and the obvious existence of data exchange often error, resulting in the flower screen, black screen, and even the crash phenomenon. When this happens, we can use the substitution method to replace the same specification of memory for inspection. Of course, if the video memory is integrated on the motherboard, we can only send repair.

　　Six, capacitance problem

RAMDAC (Random Access Memory digital-to-analog Converter) and filter capacitance are two important factors that determine the quality of the graphics screen. And the entire filter circuit work quality and capacitance quality is mutually linked, when the use of inferior capacitance or due to the capacity of its own characteristics of the decline, the appearance of flower screen, black screen phenomenon will be used to. In the solution, we can first use a multimeter to check out the problem of the capacitor, and then with the replacement of the specifications, so that the problem can be solved.
