Vibrating iPads

[sekazi]

I know the feeling he is talking about because I have been in many situations where there was a short to a metal casing. To me it feels like the vibrations of a 10000 bees make on a wall from buzzing. If I had to compare it to a sound it is close to the sound a large transformer makes.

I have not experienced it with my iPad 3 though.

Completely normal on all of Apple's aluminium products (MacBooks, iPads etc.) when using the short wall adapter.

Switch out the plug for one of these, and it will go away.

OP, there is a known electric "tingle" that has the sensation like there's a very minute vibration as you run your fingers on the edge of any aluminum Apple product. That is symptomatic of a need of a better ground.

In some homes I see people daisy chaining their power strips and connect their Apple devices to the one furthest away from the wall outlet itself. The remedy is to either use the power strip that's closest to the wall or swap the 2 prong for the grounded cable.

The title sounded like a New Sanitary Napkin LoL

My 3rd Gen iPad is doing this. I actually thought I was imagining it at first but I can feel it when I lightly pinch the ipad between finger and thumb or gently lay my hand on the back. It happens wherever I plug it in and I don't get it with my MacBook Air. I'm not worried about it in the least as can't see it being a fault with the ipad or even causing a fault.

While the store iPad was sitting in an official iPad dock charging (240v) I ran a flat palm across its back. This was roughly where the battery was. I felt a 'vibration' in my hand. This was NOT an electric shock. It really did feel like the iPad was vibrating. An 'oscillation', if you like.......

The iPad 2&3 have MEMS gyroscope chips (made by STMicroelectronics) to detect orientation. It may be that you have sensitive hands and can detect the spinning micro disk.

People have clearly answered the question as to why it does this and your reason is not why.

Sorry I didn't realize that one of Apple's engineers had already identified the source of the OP's vibration on this thread.
