Defiantly not, Dell M501 has stupid short cuts that doesn't let me game. Should I buy a keyboard if anything doesn't work because it WAS working on a cheap keyboard.
Normally to disable wireless, you have to use multiple keys FN + F2 (I know thats not what you want). Is it possible a key is stuck? I remember on my laptop if I'd push the P key I would get a different character. I corrected the problem by pressing CTRL+ALT and the offending key. So, CTRL+ALT and F2 should resort the F2 key into its normal state.
