Judging from the screenshots, it may have something to do with the wiring of the laptop display. In this case, it is recommended to ask a professional engineer to do a test in the official after-sales service center to confirm the specific problem and do targeted treatment. It may only be necessary to disassemble the machine and reassemble the cable, which is subject to the actual test results of the engineer.
It is not recommended to try to disassemble the machine by yourself, so as not to affect the warranty of the whole machine or the function of other hardware.
The official after-sales service center can be found on the official website in the following sections:
-
It should be the virtual soldering of the graphics card or the virtual soldering of the video memory, and the switch to the core display will return to normal, and it will not be very expensive to repair, dozens of dollars.
-
The monitor doesn't work, or the graphics card connector is loose.

Display screen is an extremely common failure, there are many reasons, different reasons for the fault phenomenon is also different, the solution is also different. In the text mode, the screen is characterized by confusion of characters, and in the graphic mode, it usually appears as a graphic layer, and horizontal stripes are produced due to internal or external interference. Here are some common wind failures and solutions:
1 Displays produce horizontal streaks: there are two main reasons for this:
1) External interference, such as electric sparks or high-frequency electromagnetic interference around the use site of the display, this interference will cause the display screen of the display to produce white horizontal stripes. Solution: Avoid using the monitor in this situation;
2) Internal interference, this interference will make the display screen of the display appear black horizontal stripes, in this case, you can open the case to check whether there is a bad contact inside the display, whether there is a problem with the output end of the power supply or the output transformer, etc., because the reasons for this situation involve more professional technology, so it is best to ask a professional to repair it.
2. Blurred screen caused by improper display resolution setting: When the monitor resolution is set incorrectly, there may be blurred screen failure when starting Windows, that is, the screen is layered, shaky, and even black screen of death. Solution:
Enter the safe mode and reset the display mode of the monitor.
3 Conflict between the display card and the Chinese system: In this case, when exiting the Chinese system, there will be a blurred screen, and there is no response to random keystrokes, similar to a crash, processing method: input at this time"modec080"can be resolved.
4. Poor heat dissipation effect of the main control chip of the graphics card: This will also produce the phenomenon of blurred screen failure, and the solution is to improve the heat dissipation performance of the graphics card.
5. The video memory speed is too low: When the video memory speed is too low to match the speed of the host, the screen will also be blurred, and the solution is to replace the video memory with a higher speed, or reduce the speed of the host.
6 Video memory corruption: When the video memory is damaged, there will be a phenomenon of blurred screen messy characters when the system starts, and the solution is that the video memory bar must be replaced.
7.Virus cause: Some viruses will also appear when the screen appears, and the solution: use antivirus software to eliminate it.
There are many possibilities for this kind of problem.
First of all: you need to rule out whether the black screen is due to software or a wrong setting on your computer. caused by the problem. >>>More
It's likely that you're too anxious to log in to QQ before the boot loader is completed, QQ has a bata version, the performance is very unstable, I have had a LZ situation before, only uninstall, reinstall the system so that you can purify the system, you don't want to install the system, you can use the 360 first aid kit to give first aid, and then use 360 boot start item management, prohibit the need to start, but the best thing is to restore the system, that can be completely solved. If there is still a problem, it may be a hardware problem, such as too much dust in the cooling fan (this needs to be disassembled and cleaned, it is best not to get it yourself, please ask for after-sales help) I hope LZ can solve the problem as soon as possible and surf the Internet happily

First of all, we should do the hygiene, especially the heat dissipation part. Then check to see if the fan is broken.
It depends on what price you want. What brand do you want, today's computers are getting cheaper and cheaper than before, and the configuration is getting higher and higher. The general price is about 4,000, it's good, I don't know what you're for, Lenovo's brand is good, and the after-sales service is good. >>>More
