iPad 2, iOS 9.3, cannot reactivate iPad
Try a forced restart - After shutting down all open apps using the app switcher - invoked by quick double press of the home button and swiping up on each app till it flies off the screen.
Hold the sleep/wake and home buttons down together till you see logo - then release and allow normal boot up
If that does not help - try a restore

If that does not work - you may have to try DFU (Digital Firmware Update) mode

As a last resort Please make a Genius appointment at an Apple Store, or go to another authorized service provider.
