So my Ipad 2 finally died today after two days of HEAVY use.
When I plugged it, it started charging (red battery screen).
I check it two hours later and it is only at 6% and its not charging. ***?
So I unplug it from that outlet and try another... nothing.
Try a hard restart (home + sleep buttons)... still nothing.
I remove the usb from the AC adapter block... still nothing.
Finally, I just plug it into my macbook via USB and it starts charging.
the USB is working fine... the wall charger block is NOT AT ALL working.
