Apple has posted a new support document regarding unresponsive, black-screened iPad Pros:
If your iPad Pro stops responding and the screen is black
Learn what to do if your iPad Pro doesn’t respond when you press buttons or tap on the screen, and the screen is black.
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.
This document will be updated as more information becomes available.
MacDailyNews Take: In other words, it’s the same as a force restart for any iOS device as Apple has long explained, “You should force restart your iPhone, iPad, or iPod touch as a last resort, and only if it’s not responding. To force restart your device, press and hold both the Sleep/Wake and Home buttons for at least ten seconds, until you see the Apple logo.”
