Asus Rog Strix G15 : model = G512LW
The screen is not broken, almost not physically.

When i power up the computer this run perfect but nothing show in screen, also in HDMI port.
More or less 10 sec later, when win 11 is loaded , HDMI show things i mean user login in win 11.
Original or main screen doesn't works, anytime, but HDMI works fine when win11 load nicely.

When win11 is loaded , i check device administrator, and i found a system firmware error, so what i need to do to fix that, i need flash bios? what means system firmware marked as error, .
Is that the problem.
I cant go to bios menu , its like no exist bios, because f10 and enter will shutdown if u are inside bios menu, but never shut down.

I cant go inside Bios , black screen i can not see anything, the pc doenst go inside bios menu if i press f2
Let me explain when i pres f2 win11 doesnt wake up, so i use f10 to save and exit to load again win 11, but f10 and enter, doesn't work.
So win11 don't turn on again until y restat manually, presing power button 1 time to shutdown and again to start up.
