    Hi there. I purchased an Ipad 2 64GB 3G. When charging whether in the Apple dock or just with the lead when plugged in to the mains the unit feels as though there is static on the back or slight vibration. Is this an earthing problem with my house electrics or is there any ideas what it could be?

    My iPad 1 64 GB 3G never had that problem. I don't think this is a grounding problem. Best to bring it in.

    IPad 2

    I thought I read somewhere that there was a problem with Apple power chargers been sensitive to the earth current?

    You need to get the adapter replaced.

    The adapter contains a transformer inside, which is essentially many super-thin sheets of metal bound together in shellac. The buzzing is caused by one of the metal sheets coming loose, and the current running through the adapter makes is vibrate and "buzz". In time the loose sheet could wear through the wire insulation, and cause a short.

    Thanks Mate,

    I will just double check the fault lies with the charger & ipad 2 and not my home electrics when I go to work tomorrow. If its what you are saying it is I will be gutted as its only 2 days old.

    Not on the iPad (of any generation), no.

    To the best of my knowledge, there is no transformer inside the iPad from what I can remember seen from the device tear-downs, so from a "let's think this through logically" point of view, I'm just not sure what could be inside the iPad which would cause the buzzing. If it is your iPad which is buzzing and/or leaking current to the casing, then we're in strange new territory here.

    On the other hand, issues with buzzing adapters when plugged in are well-known and I have encountered them frequently with laptops. I have personally not heard of an Apple charger which buzzes - but it is essentially a transformer that steps-up or steps-down the current from the wall socket to supply your device, so it if makes a similar noise, it's a safe assumption that it's a defective transformer.

    Out of millions of parts and devices that Apple ship, some of them are bound to be defective out-of-the-box - so a bit of bad luck here, unfortunately.

    The iPad charger can supply 2A whereas a conventional USB port on a computer can only supply 500mA - a quarter as much. So the iPad charges much faster with its own adaptor. However, you shouldn't really feel any vibration. If the problem persists I'd take it to an Apple Store and have them check it.

    Try this for all apple power supplies .set it up next to a AM radio and turn it on with nothing plugged into usb port and see if it interferes with play of radio if you here a warbling effect coming through the speaker the supply has dry connections and is unserviceable and not a very good charger

    IPad 2 vibration

    Hi.. I purchased an iPad 2 and noticed a vibrating feeling when I run my hand over the back cover!... This only occurs when the unit is charging.... It's not an actual vibration.. Just a vibrating feeling occurring in my fingers! Also if someone else is holding the iPad or I put my other hand on the back the vibration seems to stop so this must be earthing it or something!! Sounds similar to other comments on here!! I'm not sending it back though as I've waited a month to get it!!!

    Outside my iPad, or was it inside?

    Maybe an odd question, but could it be, that induction is taking place, I.e. when the battery is getting charged, it creates a magnetic field. And since the back cover is aluminum, the circuit would be completed by touching it?

    my ipad 2 wifi battery is draining too fast. i have firmware 4.3..1, and did not upgrade yet, anticipating jail break. apple offered to swap my ipad 2 so, it might have 4.3.2, should i take a chance? i dont think there is any point saving my shsh 4.3.1 with tiny umbrella, if it is machine specific and wont be able to use for a new replacement..confused..please advise me.

    thanks

    Sorry for resurrecting a dead thread, but I have to write something.

    I have the same problem as the thread creator. Brand new iPad 2, bought from a good dealer, all original parts.

    In bed right now, with a homemade stand (folded DVD case) and charger plugged in. I have the stand on a book, which in turn is in my lap. Earphones (good quality) plugged in. Buzzing noise.
    When I touch the back of the iPad, the buzzing stops. When I hold it in my hands, the buzzing stops. When I sit on the floor, book in lap, stand on book, iPad in stand, there is no buzzing. But when I get into bed, there is a noise, and if I stroke the back of the iPad, there is a feeling as if the thing is vibrating, or perhaps sending a low voltage current through my body.

    So I'm thinking grounding problem. Either that, or it's just the standard Apple problem: good design (aesthetically speaking) but lacking in build quality. Why doesn't the keyboard have arrow keys btw? Damn it. Good night.
