Key Board Troubles

I am typing this on an Acer netbook, and in order to type, am having to hold the function key to stop the 'number pad' from converting half my letters to numbers. Ive rebooted, I've tried attempted to turn the number lock off via the f11 button. but still it remains stuck on.... any advice?

Ha! Got it, finally. damn multifunction keyboards and hubbies with big hands.

That's what you get for buying an Acer. Lol
