Poor hardware contact: Hardware such as memory modules and graphics cards are like the heart and eyes of a notebook, and if there is a problem with the connection between them and the motherboard, the computer will be "blind" - a black screen. Hands-on friends can try to replug and unplug these parts.
System failure: The operating system can sometimes be emotional, and a failed update, a virus invasion, or an incompatible driver can make the laptop go black. In this case, restarting your computer and trying to boot in safe mode, or repairing the system, can often resolve some of the issues.
Screen glitches: If you exclude all the above soft reasons, then you should consider whether there is a problem with the screen itself, such as backlight plate failure, LCD screen damage, etc., at this time, you can only ask professional maintenance personnel to diagnose**.
BIOS setup issues: Finally, let's not forget the BIOS, the big guy behind the scenes, the misconfiguration caused by misoperation may also cause a black screen on boot.
