    Hi guy's once again, the problem I have is that when I plug USB lead in my ipad2 says not charging. I always do a quick search before posting but found nothing.

    It's charging, just VERY SLOWWWWLLLYYY... even though it's saying 'NOT CHARGING'..

    the iPad's charge block is rated 10W, and your USB port doesn't push enough power through it for it to trigger the charging icon... that is all..

    there is absolutely nothing wrong with your iPad..

    when charging on a laptop or desktop, be patient and enjoy... :D

    Have you connected the USB cable to a pc/laptop?

    The iPad draws a current of 10A and only the iPad wall charger supplies this current. A pc USB supplies a much lower current and will thus only trickle-charge the iPad.

    I hope it's not drawing 10A.... :). The battery would last only a few seconds if that.

    For the OP,

    USB only puts out around 5 watts and 1amp. That is why the iPad charges much slower connected to a PC/laptop vise the supplied 10 watt 2 amp power block.

    @sjleworthy: Using and 'Made for iPad' certified 3rd party charger/USB adapter or the supplied power pack.

    Any other method such as connecting to a 'standard' USB port, other iPod/iPhone-only chargers will either (as mentioned) result in a extraordinarily slow charging time or only serve to reduce the battery loss of the iPad i.e. providing enough charge for the current battery level to remain the same or discharge the battery at a reduced rate than normal.

    Or if you have money to burn, a new SandyBridge generation MBP USB port will work just as well as the supplied power pack :)

    Optimal way is always with the supplied charger, but the USB port on your pc or laptop will do you just fine, so don't run out and buy anything..

    Have a little patience and just let it charge.. The battery on these things last 10 hours, they won't charge back up fully in 20 minutes, though we all wish they could... lol

    Plug it in the wall with the white cord it came with.

    What sweetp0ison said.

    I charge by USB once in a while, it's like a trickle charger.
