Well, I guess that means the Display is NOT working? I guess you could use a secondary monitor (if it is capable of using one) and see if it shows the BIOS boot screen and go from there? If it does, create a USB drive to load the BIOS EXE file on it and it might load? This might require repair though before you can do anything?
I updated my laptop this morning to windows 11 22H2, but now it won’t turn on. The only thing I can get it to do is when I click the power button, the keyboard lights up, the charge indicator flashes orange 2x, then white 7x, then powers off.
