Sometimes, after installing some software or hardware drivers, you may find that after restarting, the computer cannot enter the system and the screen remains black. This situation is a black screen on the laptop caused by software. If the black screen is caused by software, taking the Windows system as an example, you can restart the machine and press the F8 key several times during startup to bring up the system's startup options menu.

After the system startup options menu comes out, choose to enter safe mode. If you can enter safe mode normally, you can delete the software or drivers installed before the black screen in safe mode. Then restart the machine to see if the laptop can solve the black screen problem.

Second, the laptop screen is black due to hardware.

The reasons for the black screen caused by hardware are as follows:

1) Causes of static electricity. Sometimes static electricity can cause abnormalities in the notebook motherboard circuit, resulting in no response on the screen after the computer is turned on and powered on. You can try unplugging the laptop's battery and power supply, and then pressing the laptop's power button a few more times to let the machine discharge static electricity. Then connect the power supply and turn it on to see if the fault can be solved.

2) The memory is loose or there is a hardware failure in the memory. A laptop has several major components, including CPU, motherboard, memory, and graphics card. These components are indispensable. As long as there is a problem with one of them, the notebook will not be able to run normally. The most common one is that it will not respond when it is turned on. Generally, the probability of CPU and motherboard failure is relatively small. It is common for laptops to fail to boot due to loose memory. At this time, first remove the battery and power supply of the notebook. If it is not difficult to remove the computer, you can open the back cover of the notebook yourself and replug the memory. After plugging and unplugging the memory, power on and start the machine to see if the fault can be solved.

3) The laptop’s LCD screen component is faulty. This may happen to some older laptops. Display components generally include display screens, data cables and some other small parts. If you have a desktop monitor, you can try connecting it to the VGA display interface on your laptop, and then switch the display to a VGA external display on your laptop. If you can switch to an external monitor, it means there is a bigger problem with the display component.

4) Graphics card hardware failure. The graphics card is the source of all display output of the computer, so there is something wrong with it, and no display can be seen on the screen. If the graphics card is broken, the average user cannot solve it. They can only find a computer after-sales service to solve the problem. If your laptop is within the warranty period, you can take it for free inspection and repair.
