Let you get to the un-named make, model laptop's BIOS?
If so, here's an old problem to read about -> http://www.siliconguide.com/qa/forum/messages/340.shtml
BAS13's answer is the usual for that one. The times I've run into this is when people install mouse and/or keyboard drivers. Hint: Don't.

Keyboard stopped working. Tried four other kebrds; usb and ps/2.
Tried three restore points prior to problems. Didn't help.
TIA for any help.
