iPad Not Charging Over USB? You Need a New Computer

The iPad won't charge using the USB 2.0 ports of some older machines, like my $2,500 Mac Pro from 2006.

Lots of people are complaining that their iPads aren’t charging when plugged into their computer’s USB port. The battery indicator in the upper right corner says “Not Charging.” The iPad still syncs, however.

Don’t worry, it’s not a glitch. The iPad needs a high-power USB 2.0 port to charge, which are less common on older computers. Many USB hubs and keyboards with USB ports won’t work either.

The complaints seem to be coming from users of older Macs and some Windows laptop users. The front-facing USB ports on a 2006 Mac Pro, for example, don’t put out enough power to charge the iPad, but the ports on a 2009 MacBook Pro (13-inch) do.

Apple has published a support document that advises charging the iPad using the included power brick.

Better get a new Mac to work with your new iPad.
