what i change in BIOS settings are :

• ■ Launch CSM - Disabled

after that, i press F10 to save changes and exit.
laptop will restart, but when restart i got black screen.
Keyboard light, Notification Light all lights up, Fan is running.

If you can get back to the BIOS reset it to optimized defaults
