    I know that iPad is not supposed to charge when plugged into the PC/Mac. However, Recently, after the 9.2 iTunes update, it has been.

    My iPad yesterday had 79% left on the battery. I plugged it in to sync it up and left it connected last night. This morning I woke up and it was at 100%

    It still says not charging on the iPad screen, but it seems to be slowly charging anyway.

    Anyone else experience this?

    Mine has always trickle charged when let plugged in overnight. I haven't upgraded iTunes yet.

    Edit: the iPad has always said it is not charging when plugged into my lappy.

    I think it depends on the computer. My iPad charges when plugged into my late 2009 17" MBP... slowly.

    Mine charges fast when plugged into the back of my iMac, although it still says not charging. It trickle charges when plugged into my keyboard's USB port. You guys don't even wanna be trying that with your laptops though, do you?

    Ipads have always been charging when the screen was off while connected to USB that is unless your USB port has enough voltages. This has been talked thoroughly all over the internet. PC USB ports have less voltages than MAC USB ports but even MAC USB ports take really long time to charge Ipads. Your fastest way is to use wall-outlet charge.

    Really I'm getting sick of people asking dumbarse questions like this. How about we use something called grey matter and logic. The iPad will not charge at it's normal rate as it does from the AC adapter because USB ports (powered or non-powered) cannot provide the current required. A USB port only works in mw (milliwatts), not watts. Hence why the AC adapter is rated at 10 watts, and hence why the "not charging" notification is active on USB mode.

    Just charge it with the AC adapter, after all why do you think they included it if not required. This info should be put as a sticky so no more people keep asking. The version of iTunes has no correlation in any way in regards to charging.

    All of the laptops and desktops that I own charge both of my iPad's just fine. The only laptop that will not charge either of my iPad's is the POS one provided by work. It gives me the 'Not Charging' notification.

    I've always read that it is computer dependent. Some have higher powered USB ports than others.

    Yea, the 'not charging' message confuses a lot of people. I don't need fast charging much of the time, so I just plug it into my Mac Mini since it is on anyway and let it charge slowly, no biggie.
    If the screen is on, it's true, it isn't charging, turn the screen off to let it charge.

    I have had my iPad doc plugged into my usb hub since day one. I've never charged it any other way than my MPB.

    The iPad uses about 2.5 Watt when turned on. USB can supply about 2.5 Watt. The iPad charger supplies 10 Watt. So if you plug the iPad into your Mac and use it, it gets just about enough power to run, but there's nothing left to charge it. Still, you can use the iPad for ages that way (not if you use a MB or MBP that is not plugged in; its batteries will empty a lot quicker with the iPad connected).

    If the iPad is turned off, you get 2.5 Watt to charge. So it will charge, just a lot slower than with the wall charger.
