I thought the USB (Synching) doesn't charge the iPad?

    It even says, "Not Charging" but I woke up just now to find my (64GB/3G) iPad fully charged.

    Did Apple made changes to 4.3.1?

    Even when the iPad says "Not Charging" it charges, but at a very, very slow rate.

    I'm not sure why yours doesn't say that its charging because it does.

    It depends on the computer. Some (generally newer) USB ports can provide enough power to support the current draw the iPad needs to charge, but older ones have a lower current rating that doesn't necessarily support the iPad. It looks like the iPad will say "not charging" if connected to a USB port that doesn't have the specs to support, even if the iPad is actually charging, though at a slower rate.

    It's similar to the "bricks" Apple provides for charging. The smaller iPhone "cube" is rated at 5W (as I recall), and the larger one supplied with the iPad is 10W. I plug my iPad into the iPhone charger fairly often and it does charge, but I think it's slower than the 10W iPad charger.

    See this article on Apple's support site.
