One day the sleep button just stopped working so I tried resetting it and now its stuck on the start up logo. Itunes won't recognize it and neither will the computer! I've tried looking it up but its either one case or the other never both. Does anyone have a clue how to fix this? Please and thank you if you do! And I've changed my start up logo so that its not the apple logo anymore but do you guys think apple will do anything for me since I am still in my warranty year.
