Question

Computer shut down and will not reboot. Boots to scree that says press f2 for setup, and on bottom press f12 for boot device setup menu. Each option asks for a password. I have tried every password I know and no luck. Is there an override password?
This is not my computer, I was contacted by a friend for help. all I have is the serial # for the product.
