ipad shut down and won't start again!

That's what happened to my iPhone and I think the best way to prevent it is to leave it for a couple of days cause that's what I odd and eventually it worked when I put it in charge for like a whorl three days

Your battery could have some issues, maybe try charging it for an entire day. You could also try different combinations of home button and power button presses after charging. You can search that on the internet. If you charge it and the back feels hot where the battery is, your battery might be dead, which happened to one of my iPods. Then you’ll have to replace it.
