Body steps
1. If your ipad is black screen, press home is not any response, this estimate is the software caused, we can try to long press the power to reboot.
2. If the power supply is still not used, it is estimated that the crash is more serious, we can try to press "home+ power button" long press about 10 seconds or more.
3. If we press the power supply is useless and press the Power +home also useless, it is possible that the ipad is out of power, you can charge a try.
To sum up
1. First determine whether the phone has electricity! Try to charge first, if you are sure there is electricity, please see the next step
2. Press and hold the Power-on key and the home key, do not let go
3. About 10-16 seconds, the machine will reboot. Normal access to the system!
(Sometimes the system fake panic, it will appear this case)
Small Tips
The black screen solution can also be applied to the iphone, because the ipad and the iphone are the same way of doing it.
