iPad Air screen is black and unresponsive 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?
I like to connect devices with no visible display to iTunes and see that I can make a backup of the device. At that point, I follow the 6 step process (even if I don't think the first few will work, sometimes going through the shutdown motions revives the screen.)

If you can make a backup, you have a good base and then can try a restore. Also, if you haven't powered it off, that might do the trick without needing a computer.
