    Note the percentage of power. Plug the iPad in. Put it in sleep mode. Come back in 30min-1HR and recheck the percentage. Did it change? It seem's to charge just fine, as long as the screen is off, and it is sleeping.

    Out of curiosity, how old is your Mac Pro? My three year old MP won't charge (at least with the screen on).

    Thanks for the info. Too bad my MP (dual quads @ 3GHz) is still enough machine for me. I therefore won't be upgrading any time soon. Funny, I never kept a PC for more than 3 years .

    Re: Charging from computer?

    The keyboard on any Mac is low power. It may sync but will not charge. I will check with my support guy but I think the rear ports on Mac pro are high power front are low but unsure

    I just tried the rear USB port on my Mac Pro, no luck. I guess I'll just get a high powered hub when I find an iPad compatible one .

    Yes,

    Charging from some USB ports, especially on PCs,
    will not work.

    Here is an article on MaximumPC, discussing this.

    Apple apparently designed the IPad to need just a bit more than the USB 2.0 standard.
    Many people are suggesting it is a plot to make PCs look bad in comparison to Apple.

    It appears any powered (with a power cord plugged in) USB hub, should work.
    Probably an easy cheap fix. But it is annoying.

    The iPad will most definitely charge USB linked to a pc...as mentioned before, utilizing a well powered USB port is mandatory.

    I don't think it was to make it incompatible with windows....my portable hard drive requires more power than most pcs and g5s as well.
