    Anyone else notice this?

    Its a fast vibrate that can be felt by touching the back of the case. The vibration disappears when any sort of pressure is applied by your fingers.

    This dont seem right:confused:

    I don't think it's vibrating.

    AFAIK there is no vibrating motors in any iPad. I've noticed that when my iPad is charging if i run my fingers along the back of it i can 'feel' the electric current. Its difficult to explain but I've noticed it multiple times.

    Maybe you're noticing the same thing.

    Edit* Found this
    ou may or may not have noticed, but if you run your hand along the back of the iPad (or even an iPod touch) while it’s charging, especially when using a wall power adapter, you may notice a vibration or tingle sensation on your hand. You might be wondering what it is. This article is short and sweet, so let’s explore.

    Charging your iPad

    When you plug your iPad into a wall outlet (or any charger for that matter), you would think the current should go into the device alone. Well, it doesn’t. Some of the charge is dispersed along the metal case by design. Here is a comment on Apple’s forum quoted from Apple’s support team regarding this issue:

    There is measurable AC voltage across the external metal parts when an iPad charges. The measured voltage is within the SELV (Separated Extra-Low Voltage) limit, which means that the iPad is safe to touch. Additionally, the touch current is within the safety limit according to UL/IEC 60950 (Safety of Information Technology Equipment).[1]

    So, there you have it. This is by design and nothing to be concerned over. Although, what Apple should have done is take that current being dispersed onto the case surface and run it to an LED to soak it up so you feel nothing. Of course, that means the iPad would need an external LED, but it wouldn’t be a bad thing to know when the device is charging without having to turn it on.

    Great point about the lack of motors.

    I guess most people have a cover and never feel it.

    Mad though - but thanks.
