The screen of my 2014 iPad Air, is black and unresponsive, currently the alarm is going off (so I know it is working) but the screen is black and unresponsive. I have not dropped it, I have tried to power it off, but since there is no response, I don't know whether it had any effect.
I have charged it fully overnight. I tested the charger on another device and it works fine. I don't have another Mac computer to connect it to. Yesterday was the first time I used Siri, could that have something to do with it?
What else could I try?
