Umm...did your ipad run out of battery? I mean once drained to zero it takes about 2 to 3 minutes for ipad to comeback after connecting to the 10W charger. And in zero battery state ipad wont turn on at all,but with little power it will show a red battery too. Its obvious but most often people miss obvious stuff and panic resulting in total frustration. There is a possibility of overheating too which shows a notification though. Connect to the 10W charger,wait for 5 minutes and then hold the power button and see if it comes back. What happened before total die out? Did it just die like that while using your ipad or you just left it and it went out?
Thanks
