iPad no longer charges
Up until yesteday afternoon, my ipad 3 would charge while connected to my imac (I use my ipad all day with Noteshelf at work, so for convenince have it attached to my imac to charge).
Anyway, yesterday afternoon, my imac stopped charging the ipad. I've checked the usb slots (at the back of the computer) and none of them work. I've tried the same and different usb cables with mine and other ipads and iphones - seems, iphones charge okay, but not ipads...
iTunes still recognies the ipad though, so its connected, just not drawing power!
Any ideas?
iMac, Mac OS X (10.6.7)
