Troubleshoot Your iPad: Restart
If you recharge your iPad and it still misbehaves, freezes up, or won't work right, the next thing to try in troubleshooting is restarting it. Just as restarting a computer often fixes problems, restarting your iPad sometimes works wonders.
Usually, all Apple’s iOS devices — namely the iPad, iPhone, and iPod touch — are fairly reliable. But every so often, a good iPad might just go bad. It won’t be a common occurrence, but it does happen occasionally.
What kind of bad things could happen? Well, they may be problems involving
Frozen or dead iPads
Synchronization of computers (both Mac and PC) or iTunes
Follow these simple steps to restart your iPad:
Press and hold the Sleep/Wake button.
When the red slider appears, slide it to turn off the iPad and then wait a few seconds.
Press and hold the Sleep/Wake button again until the Apple logo appears on the screen.
If your iPad is still frozen, misbehaves, or doesn’t start, press and hold the Home button for 6 to 10 seconds to force any frozen applications to quit.
Repeat Steps 1 to 3 again.
If these steps don’t get your iPad back up and running, move on to the third R, resetting your iPad. The seven steps for troubleshooting your iPad are: Recharge, Restart, Reset your iPad, Remove your content, Reset settings and content, Restore, and Recovery mode.
