ipadpro 12.9 inch yesterday suddenly shut down while working on it (Drawing app). Would not restart for an hour. When i connected it for loading it started again. noticed it was still full at 57% , so that was not reason. It shut off again after 5 min. Could not get it started again. I tried restart with top button and top with volume button. nothing happens, i can still hear it clicking on off, can activate Siri, screen very dimly lights up. Possible reasons? I got a message yesterday morning that the Ipad had updated automatically, so it will be latest IOS. I am on holiday so do not have laptop with me. Yesterday also reconfigured Face ID. I read at other forums it could have to do with update. what to do? I do not prefer hard reset for the data. Would people in Applestore be able to connect via laptop maybe? Thank you for help!
