Hi! I bought an iPad in february. It charged OK for the first couple of months, then all of a sudden it wouldn't charge up from the wall outlet. Now it will only charge if i first plug it into my Mac mini desktop, then plug it in at the wall. If i unplug it from the wall and plug it back into the wall, it won't charge. Here are the things i've tried. Used another charger - same problem tried my chargers on other devices - they work fine my charger is the 12w one and came with the ipad I have done a reset I have updated the OS time to send it back?
