Hello everyone. I've had an iPad Air for just over a month now. I have been using it today as normal and then closed smart case cover over the screen as usual and off I went out. Came back in, opened the cover, no response. Weird, I thought, as I had over 50% battery when I left it. So I thought, maybe the battery died - so plugged it in. It has been on charge for over an hour and won't come back on. What can I do?! I really don't understand or know what to do. I googled it and the only thing I got was to hold the home button and sleep/wake button for 10 seconds but apparently that resets everything which I don't want as I've never backed it up to iTunes. I know, I know - silly. Any idea? Why would it just die? Thanks for any help in advance.
