sorry I missed the bit that you said it was a laptop

if you have problems with the keyboard in the bios, then it looks like the keyboard has a fault,

usb keyboard is best bet, fixing will be stupid expensive probably.

one of the kids broke the up cursor key on her laptop, went on ebay to find keyboards, silly expensive, and for that make and model of laptop there were several up keys, all slightly different, so usb keyboard that we already had was my solution.
