Solve : Disabling the F3 key on a laptop?

1.	Solve : Disabling the F3 key on a laptop?
Answer» Hi, We have a laptop with an annoying habit. When just sitting there with no one touching it, search windows keep popping up. I have scanned this PC for both malware and viruses but it is a clean machine. So, there is one conclusion we here have come to. The F3 key must be a little dodgy. It is probably GIVING out SPURIOUS signals which result in search windows appearing. I have LOOKED on google to try to find a way of totally disabling this F3 key. However, I can only seem to find solutions for disabling F3 in internet explorer. They don't AFFECT the F3 key when the desktop is being displayed. Can ANYONE tell me how to completely disable the F3 key at all times?
