    The power requirements are too high for the computer's USB port. It's not as if Apple forgot to implement charging that way.

    The cable that comes with the iPad need 10 watts. So plug it on the wall that's what Apple is tell everybody to do not on a UBS computer.. iPad is not build the same as the other Apple products.

    If is still doesn't work try restore iPad on iTunes that's going to work.

    Grant, the iPad will charge when it's in sleep mode. Make sure your MacBook is NOT in sleep mode.

    Surprisingly it won't charge from any USB port on a beast of a Mac Pro either, which seems odd.

    It doesn't really matter what MAC you have...MBP or MP the USB power output is not the supported charging channel...

    Some folks have been able to get USB to charge but it will take twice as long and will be quirky...use the supplied wall charger

    Even powered USB hubs don't give the needed 10 watts

    I have an older Dell PC.

    At first I didn't think that the iPad was charging because it always said Not Charging when I looked at it. Last night I left the iPad plugged into the USB port with about 50% battery remaining.

    This morning it was 100% charged!

    If one USB port is not enough to charge it they could have put a 2 port USB charger in it, like some hard drives.... A frend has a external hard drive that came witha cable with 2 usb connectors and one connector for the hard drive. If he needs to he plugs both USB cables into his laptop and this give the hard drive enough power to run.


    I am sure apple might come out with something like this if there is enough demand.

    USB ports output in volts...not watts... iPad charge produces 10watts to charge and power iPad...USB 2.0 or 1.1 outputs 5volts... so it doesn't matter if you have a 4 head USB connector for iPad it doesn't have 10 watts of power...computers only output 5volts per USB port...

    So 5 volts and 0 watts. That makes no sense. Wattage is power. Zero watts means no power.

    Not exactly...

    USB outputs 500ma at 5volts

    MA is Milliamps... there are 1000 milliamps in 1 watt... so USB outputs the equivalent of half a watt...the supplied wall charger is 10watts...USB just doesn't have enough juice to compare to the wall charger and thus charging will be very weak and thus why Apple doesn't recommend USB charging
