Tingly MacBook battery

Parents bought a 2012 non-retina MacBook in India (where they are ATM). I got an email saying the battery vibrates when the MacBook is plugged in. Maybe something to do with it not being earthed; I think they use two-pin plugs over there.

Anyone else have a tingly MacBook battery? Would it clear up in the uk where we have three pins? Is it dangerous or bad for laptop? Parents are bit concerned.

I thought the AC adapter for Macbooks doesn't have an 3rd prong for earth on it regardless? At least that's the case in Australia and Japan.

I would take it back to the store ASAP.

I would take it back as well. And in the U.S. the plugs do have the grounding pin.

Ok, thanks. I'm getting two different sets of opinions which is interesting. On another forum a few people had had the same issue and weren't concerned. Happens with iPads too, apparently.

Will pass you recommendations on.

I would suggest calling Apple and asking them.

Interesting, I didn't know that. Any idea why it's different in the U.S.?

In the US, if you use the grounding plug, everything is good. If you use the two-pronged plug, the aluminum casing of the MacBook Pro will vibrate/tingle, ever so lightly. It's weird, but it isn't a flaw, it's the design (I guess). Found others online with that issue when I was looking into it.

Is that just on new Macbook Pros? Obviously mine doesn't do it and I've never heard of this problem before from other 2 pronged users.

Mine is an early 2011 13" MacBook Pro that I'm feeling it on.

Mine is early 2007 so definitely a few revisions between ours.

The only entity that can answer that question with certainty is Apple, and I would suggest that feeling electric current in the metal skin of your laptop is something you should call the manufacturer about.

I don't recall that at all from my late 2008 Pro or 2010 Air.

Had an old gateway that did that on the solid aluminum bits. What's relevant here is that I could feel it, but Sthillary and my mom couldn't.
