Hold the HOME and SLEEP buttons at the same time for 10-15 seconds, until an Apple logo appears.

While you could take it to an Apple Store, this is what they will do when you get there.

Same thing happened to me and this advice worked, thanks. I also made sure it was plugged into the Mac when I did it, it didn t work unless plugged in.
