Is anyone else having issues with charging their new IPad from the computer's USB port. I have the dock plugged directly into a late 2011 I7 27" IMac (no Hub) and the IPad shows not charging, seems strange.
If you see it saying "Not charging" its because the screen is on and the iPad is active.
It'll charge even from a standard USB port as long as it is not in use at the same time (screen off). It'll take forever to do it since that's a quarter of the power from the supplied AC charger, but it'll charge.
I know I know *huge audience groan* but I have not upgraded to MBA yet. I've had the first generation iPad and now the 3 and neither have charged while plugged to the USB port of my laptop.
One thing I did notice, however, is how hot-to-the-touch the AC adaptor becomes when plugged into the wall outlet. The male part of the cord itself that is plugged into the square thingey becomes VERY hot.
I've not experienced this with my original iPad. Is this a defective product that I need to have replaced or is this the general accepted consensus - being all warm n such, I mean?
One thing I noticed right off is that the new iPad 3 won't charge from my Mac Pro (late 2008) with a heavy-duty, third-party 6' USB extension cable, even if it's plugged in directly to a system USB port. It does seem to work, however, with Apple's own thin 3' extension. Neither the USB ports on my 23" Cinema displays (same era as my Pro) or a USB PCI card I'm using provide enough oomph.
Gefen and some other companies make USB extenders that may help. My issue is that I have a somewhat long cable run to my CPU.
