I have macbook pro got it last year and the f3 button which exposes the windows i have open is not working. When i press the button basicly nothing happens no dimming of light no nothing. I remember it happened before a month or so ago and i fixed it by following someone elses solution but now i cant find where i got that information from. I think i remember going into terminal typing something and then after going to macintosh, library then preferences but i cant remeember what to do.


If any body knows a solution that would be great. I have 3 windows open so its not a chase of having just 1 window open it was working fine last night. also does anyone know what triggers it, my mac completely ran out of battery would that be why?


Many thanks

MacBook Pro, Mac OS X (10.6.8)

    Choose Apple menu > System Preferences, and then click Keyboard.


    Check whether the “Use all F1, F2, etc. keys as standard function keys” checkbox is checked.


    If it is check, uncheck it.


    A power-outing can indeed be the case that such a setting is reset.

    I had this problem. Try searching for Mission Control in Spotlight. Once you do that pull it down to the dock. Open it. Go to an open window. hit f3. It should work then.
