    No boot, fan spins, keyboard lighting on, probably bios corruption, reprogammed chip with bios dump from https://vinafix.com/threads/acer-aspire-vn7-791-791g-14203-2.14775/ post #6

    now pc seems to boot normally, normal fan sequence but no image on screen.

    I want to check if the bios I reprogrammed is the one I was supposed to use.

    Attached original bios. Thanks!

    Bios I send is original backup after laptop no boot, both fan spins at start, then only small fan accelerate every 2-3 seconds forever, my prediction is bios corruption.

    No errors in bios?

    normal boot, nothing strange with fans, but no image on screen.

    your bios should work normally?
