You'll have to reset the bios. Disconnect all power sources and remove the battery. Unscrew the panels on the bottom of the laptop and find the cmos battery, it'll be a small round shapped battery about the size of a nickel. Remove that battery and short the terminals together with a screwdriver or you can just leave it out for a while, between 18-84 hours.
