It's in the control panel. Also, have you tried taking the keys OUT and cleaning under them?

 

Gotcha, I'll check with the control panel later. As for the cleaning of the keys, I actually just did that a couple weeks ago. Not sure if I didn't put the board back, but considering all of the other keys work, I doubt that's the reason.

 

I'd just go for new computer.
Good Luck though. :3
