Laptop keyboard not working even in bios - usb keyboard works
Posted on 2011-09-19
I have an HP G72-250us laptop running Windows 7 and the built-in keyboard is not working at all. However, the lights on it for num lock and wifi appear to be lighting up correctly. It doesn't work even in the bios. However, an external usb keyboard is working fine.
I already tried resetting the bios to default options, updating the bios, running system restore, and replacing the keyboard all with no avail.
Does anyone know what the problem could be?
