Hi, my problem was one night I was on my ipad and it was fully charged so I turned it off. The next morning I was using my iPad and then it just went of with 50% charge left. I left it for 2 days and the day before I was about to take it to protect my bubble, I put it on charge for 5 mins and it came on! So just leve it a couple of days then charge it up again!!!!!!!!!!!!!
