Im having problems with my original 32GB Wifi iPad. When i have it plugged in to the 10W AC adapter it continually reboots only showing the apple logo for a few seconds before blanking and then displaying it again. it never gets to the "swipe to unlock" screen. using the AC adapter i can get it into DFU mode saying "connect to iTunes" but as soon as i unplug, off it goes, no response from home or power button. When i plug it into my iMac, i also get squat. no indications of life, it wont even go into the boot loop or attempt to start up. ive tried it in every usb port whilst being the only USB device. Nothing. Help please, this iPad is the last thread of sanity my wife and i have whilst staying in hospital with our 17 month old daughter who is receiving cancer treatment after being diagnosed with neuroblastoma 1 month ago.
