    I'm dealing with a K72JK with a bios problem (bios update gone bad)...... no sign of life.
    So i disassembled the pc, de-soldered the bios chip and reprogrammed with the bios file from asus web site.
    Now when I plug the power cord it "start" itself for 1 sec (i can ear the fan spinning and the hd turning on) and turns off, after 30 second it starts again but there is no boot , no hd activity, black screen, actually only the fan spinning.
    Holding the power button i can turn it off, and if i press it again the notebook start a sort of boot-loop, where the fan and the hd start and stop.
    Now I've found that this laptop has an Efi bios, and the file from asus web site is just an update, so I've to rebuild the entire 4MB bios with an hex editor, but I really need you help.
    Here you can find the 4MB corrupted bios and the 2MB bios update versions from Asus web site.
