    When I plug my iPad in to the USB port of my lap top, I get a "Not Charging" indication near the battery indicator? I'm still living off the first initial charge through the supplied adapter but really planned on charging it via my lap top or PC.

    Any ideas why?

    not enough power to charge..it will data sync tho. You will need a double USB plug to power it and sync.

    What he means is a USB port that is rated at 1000mw instead of the older 500mw outlets. Most USB 2.0 ports only had a maximum rating of 500mw due to the low power requirements that most items required. The iPad is still a 5Vdc system, but to charge while it is being used, you have to pull 1000mw of power. 500mw is enough to charge a iPad when turned off, or to maintain the charge on a actve iPad. To do both, you require a 1000mw unit.

    I have read that it should take about 4 hours to completely recharge. I wouldn't worry about your iPad. I am sure it is fine.

    The iPad has a relatively large battery. It may have half of its weight in the battery from what I have heard. The bigger the battery, the longer it takes to charge.

    I think it also gives that message when charging is complete.

    no I mean a double USB cable. It has one USB on one side and two on the other. It's for hard drives and other devices that require more power than the old USB ports allowed.

    The power required by the ipad is greater than most laptops can produce because it has bigger batteries . Exceptions are some of the Macs and some PC's that support higher voltage devices like hard drives etc
    The ipad will charge but very slow when connected and if in sleep mode however you may not see any indication on the screen the battery level however may not change

    That is why one needs either a dual usb cable or a powered hub with high out put.
    I am curious why do you need to charge the ipad from the lap top when you need to charge the laptop from power any way. The ipad charges fine from direct power lasts 10 to 12 hours just charge it when you sleep.
