If your laptop is within the warranty period, you can take it for free inspection and repair.
2. Enter safe mode and confirm whether there is a black screen in safe mode. If it is normal in safe mode, it is usually caused by software conflicts. Please confirm whether any system optimization or software installation operations have been performed recently. You can Via --Uninstall recently installed updates and software programs.
3. Check for hardware problems: It may be a hardware problem that causes the computer to go black, such as power adapter, battery, memory, etc. You can try to replace or repair the hardware. Check for system problems: Computer system problems may cause a black screen. You can try to reinstall the system or use system repair tools to solve the problem.
4. Please try to press the function key combination to increase the screen brightness and switch the display on and off to avoid the screen brightness being too low or the computer going black due to the screen being turned off.

If anything is loose or damaged, it may cause a black screen. Check the battery: If the laptop runs on battery power, unplug the power adapter and try running it on battery power.
The causes of a black screen when a laptop starts up can generally be divided into two categories: hardware and software. Black screen caused by software: Sometimes after installing some software or hardware drivers, you 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 it doesn't work, it may be caused by a problem with the system or driver software. Try backing up the data and then restoring or reinstalling the system to solve the problem.

For repairing computer black screen faults, the principle of soft first and then hard should be followed. That is to first eliminate the black screen fault caused by the operating system and application software, and then find the cause from the hardware.
If the power indicator light is on and there is air blowing from the cooling fan outlet, but the monitor is still black, this situation is mostly caused by a circuit failure or hardware failure inside the notebook, such as a loose memory module inside the notebook, a faulty graphics card, or a faulty display panel. wait.
The computer screen black screen is relatively easy to occur, especially in some older computers or assembled computers. There are many reasons for computer black screen failure, such as damage to the monitor, damage to the motherboard, damage to the graphics card, poor contact with the graphics card, damage to the power supply, damage to the CPU, etc. (1) The monitor is powered off, or the monitor data cable is in poor contact.
The monitor power cord is loose, the video signal line is in poor contact, the memory module is loose, the graphics card is loose, the monitor itself has problems. Memory stick oxidation, graphics card oxidation, power supply problems, motherboard battery problems, CPU not working, etc.
