Keyboard Shortcut Issue

[Daniel97]

I have just set up my new 2011 MBA with migration assistant from my old MBP.

My F4 key is not functioning and bringing up launchpad since doing the migrate .. despite the fact i have gone into settings and pressed restore to default?

Can anybody talk me through it?

Thanks

Had to ring applecare in the end.

It took a senior advisor over an hour to fix - Ended up deleting 4 preference files and playing in terminal to get it working.
