What caused iPad Air to go black screen and not power up? When I was on my iPad Air last night an Apple warning appeared.
Usually I can go into settings and clear it.
This one kept flashing.
I clicked the button on bottom left to re-log in.
After, I entered my password, the tablet went black and unresponsive.
Now it won't power up?

I am unsure of what to do now, any help is much appreciated.
It could be many things. I would go through this checklist and possible ask a follow on question when one item fails or you can't complete the checklist to rule out common reasons for this:
