Caps lock problem? Is it sticky or is the button straight up not working? If you spilled it with water then open it up and let it dry for a few days. If you spilled cola or something like that then you might want to plug it out, open it up, grab a cutton swab dipped in water and clean it up.

If it's the circuit itself then see what's wrong with it and see if you can get spare parts for your keyboard. try e-bay or amazon.
