I used my iPad&7 this morning shut it off and went back to it about an hour later and it wouldn't turn on, I plugged the charger in and nothing I kept pushing buttons and finely it turned on is this something to be worried about.
iPad 7 less than a year old
Try turning it off again to see if the problem repeats. If so, and even if it doesn’t, contact Apple Support to see about getting a diagnostic done. You could have a hardware fault that should be covered under the standard warranty.
Might be a problem with the power button. That’s all I can think of.
If it keeps happening, you should probably look into taking (or sending) it to Apple for a diagnostic. If it’s less than a year old the warrantee should still be good.
