I have a stone cold dead iPad 2; need advice.
An instructor brought a refurbished iPad 2 to me because it wouldn't take a charge. It was "alive" when it came to me. I put it on charge but after about 4% more charge being taken, it would stop taking charge. I examined the Settings and Notifications and couldn't find anything obviously wrong. I decided to leave it on charge overnight to see if it would start charging again. The next day it was completely dead.
My question is actually quite simple: What do I try next? I wouldn't be posting this message if it was a computer, either Windows or Mac. I know things to try with those operating systems. I am much less familiar with iOS so any help would be appreciated. Thanks
iPad 2, iOS 8.1.3
