Inspect the end of the ribbon cable that goes to those buttons, check out both ends of that cable. More than likely the cable is frayed at the end and causing a short. I had a similar issue with a g53 I had to repair. If you disconnect and pinch the cable between your thumb and pointer finger you can probably straighten out the cable enough to correct the short. You can also try to trim down the end of the cable a tiny bit to help this.

Good luck, let me know how it goes. Worse case scenario you will have to get a new fcc cable.
