The BIOS doesn't go blank when the battery dies, it resets to its default settings.
Its likely the battery is toasted. Get a new one to be sure, need a CR2032 type, cost you about a quid. Don't go to PC World though, go to a car spares shop as they're commonly used in remote central locking units. You shouldn't be paying more than about 50p-£1.
