If the iPad freezes and stops responding to taps or button presses, you can reboot it without losing data.
- Press and hold the Sleep/Wake button and the Home button at the same time until the screen goes blank.
- The iPad will automatically power on again and the silver Apple logo will appear in the center of the screen. Give it at least 30 seconds to start.
If you don’t want to reboot everything to address one misbehaving app, you can force quit a running one.
- Press and hold the Home button for 6 seconds or more until the Home screen appears.
