Seizing and Freezing
iPads rarely freeze up. But occasional malfunctions or misbehaving apps can render your iPad catatonic. Here are three methods to get things going again. Try them in this order.
1. Force quit the app. Press and hold the Sleep/Wake button down until you see the red “power-off“ slider—but don’t slide this time. Instead, try pressing and holding the Home button for about six seconds, then release. This should end the offending app and take you back to the Home screen.
2. Restart the iPad. Press and hold the Sleep/Wake button until a red slider appears. Use the slider to turn the iPad off. Pause a few moments while your iPad shuts down, then hold the Sleep/Wake button until the Apple logo appears. When you see the Apple logo, release the Sleep/Wake button.
3. Reset the iPad. Press and hold both the Sleep/Wake button and the Home button until the screen goes blank. Be patient as the Apple logo appears and your iPad comes back to life.
