What to do with the black screen after the laptop is turned on?

This article will explain in detail what to do with the black screen after the laptop is turned on. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The notebook is dormant:

1. If the computer is dormant and the screen is black, then as long as you press any key of the computer, you can restart it.

2, if you do not want the computer to sleep, then make relevant settings, such as: take the win7 system as an example, right-click on the desktop, and then "personalize", then select "screen saver", and then click "change power options"-"change computer sleep time", in the relevant settings, select "never".

Second, screen problems

1. If the boot screen is black, but there is a sound that can enter the system normally, try to connect the external screen to see if the output is normal. If the external screen can be booted and displayed normally, it means that there is something wrong with the laptop screen or wiring.

2. Perhaps it is caused by poor contact, so it is necessary to restart the computer. If it still cannot be displayed, the screen is broken. It is recommended to send it to the repair shop for repair.

3. Video card / motherboard problem

1. If the boot screen is black and a sound can enter the system, but the external screen is still abnormal, it means that there is something wrong with the video card or motherboard.

2. When dealing with it, open the shell, tighten the interface between the screen and the motherboard, then clean up the dust, and install the computer parts one by one.

3. If it still cannot be solved, restart the computer, then press F8 all the time to enter the safe mode, then carry out antivirus, repair the files, and restart the boot.

IV. System problems

1. If the black screen is caused by system problems, there will be a cursor flashing in the upper left corner of the LOGO screen of the BIOS interface. Even if there is no cursor, the screen is brighter than when it is not powered on.

2. If the above problems occur, it is best to reboot and enter the bios. After selecting the USB disk to start, enter the pe system, and after entering, repair and disinfect the system problems.

5. The problem of insufficient electricity

If the computer forgets to charge and there is no power black screen, it is necessary to connect the power supply, so the problem is solved.
