I will be brief.
The iPad died on me yesterday. I opened it and found the screen totally unresponsive – no fingerprint, wouldn't let me type in the code, couldn't press Cancel. Nada. I left it for awhile to think about things, and when I looked again the screen was blank. Blackness.
I charged it (and it made that sweet little responsive noise when I plugged it in), although I think the battery was about 30% full. I looked up Apple's help pages and tried to follow the instructions for Restarting and then for Rebooting, to no avail. So I'm going up to John Lewis now before the Saturday crowds get there and while I still have some puff.
