Penny has an old tower computer that she wants to get rid of. Leo suggests keeping the hard drive and donating the rest of the PC. She tried to boot it up to move the data off the hard drive, but it won't boot. Leo suggests that she check her keyboard connection. Sometimes a computer won't boot if a keyboard isn't properly connected. The BIOS battery or motherboard battery could have died. The hard drive may have gotten stuck. It's called "stiction." Penny should try taking out the hard drive and putting it into an external enclosure to see if she can still read the data.
