Apple has officially acknowledged an issue reported by multiple iPad Pro owners on Reddit and Apple’s own support forum, in which some units become unresponsive after charging. We’ve even happened upon a few dead iPad Pros at the Apple Store for which an Apple employee shyly asked us to avert our eyes while he did a hard restart.

Some users report that the device won’t wake after charging, while others who left it switched on say that the Pro fails to respond to either the touchscreen or the home button. The problem can be resolved by a force restart, and this is the action Apple recommends while it investigates … 

Apple has posted an extremely brief support document.

Some are suggesting that iOS 9.1 is the culprit, with the issue resolved by the beta of iOS 9.2. If this indeed proves to be the case, then affected owners shouldn’t have long to wait for a fix.

To get back to using your iPad Pro, force restart it by pressing and holding both the Sleep/Wake and Home buttons for at least ten seconds, until you see the Apple logo.

Apple is aware of this issue and is investigating.
