Hi
I've noticed that when my iPad is charging in it's dock that the back of the iPad gently vibrates and there is a tingling feeling when touched. I have found a lot of similar posts across the web but none give a definitive answer. Does anyone know if this is normal behaviour or is there a problem?
Many thanks

It's normal. The "vibration" is an electrical sensation, with a frequency that is equal to the AC imput line frequency (50 or 50 Hz). In order to meet the international radiated emissions requirements, the power adapter places one-half of the line voltage on the iPad chassis. Although it can be annoying, the current is very low - well within the international safety standards. This sensation may be alleviated by turning the AC plu 180 degrees. The sensation can be eliminated completely by grounding the power adapter or iPad, while it is charging.
Thank u. I was wonder to.
