Why doesn't the iPad charge when connected to iTunes?

[Coldsnow]

Kind of annoying, and it doesn't tell you why it doesnt charge.

The USB port can't power the display and charge at the same time. It will charge, but only with the screen off.

Some USB ports on your computer may not put out enough power, the iPad likes high power USB ports. It should still be charging even it says it isn't just at a slower rate. This should help explain

Mine charges. As stated above, you need power, and old computers may not supply it.

And some USB hubs, even powered ones don't seem to provide enough juice.

Consider this:

Your iPad wall charger provides 2.1 amps.

A typical USB port provides 500 millamps or 0.5 amps.

I installed an app on my laptop to force my usb port to charge my iPad. It's called ASUS Ai charger. It works fine on my Sony Vaio.

If there is ever a USB 3.0 version of the charger made, it should be able to handle it, but that's an if.

The iPad is a swimming pool and your USB connection is a garden hose. As long as the screen is on the drain is partially open and will empty about as fast as water goes in. Close the drain and it will fill slowly. If you want to fill it up fast you need to connect it to a fire hose (the supplied iPad 10W wart).

Google and download "Asus AI Charger"

It's a little app that runs in the taskbar, that enables the iPad to charge over USB.

NB-it doesn't matter what motherboard you have.
