Just fixed a neighbor's iPad 3. If your iPad hasn't been used for a while, you may face a problem like the screen getting stuck on the Apple logo or iPad not booting up. You can try holding the home and power button down at the same time for 5 seconds until you see the Apple logo. After that, release both buttons. Sometimes that will fix the problem. If not, try to update the iOS with itunes. If that doesn't work either, we're here to help.
