I don't know if this is the right place to seek help, I am sleepless since yesterday, slept only for 2 hours.

my problem is I updated the bios of my laptop and now it doesn't have display on laptop's own screen but I get display on external monitor, I can't reset the bios because external monitor doesn't work until windows login screen, I tried everything, even Dell support couldn't help me, if I can see bios screen from external monitor I might try to reset but no...I need a modified bios that will reset the bios settings on this laptop or something like that...

...

hello, thanks for accepting me in this forums, I hope I can find the help I need...
