electricity on aluminium enclosure?!

[kangping]

hi again

i have an issue with electricity running through my mbp. i relocated to china some weeks ago and all of it started here. its not enough to really heart me or anything, but still quite annoying… sometimes it just feels like a soft vibration going through my book.
the voltage is the same as in europe as far as i know, and the plug fits mechanically. is this a case for apple care?

its a mbp i7. thanks in advance.

Are you using the three pronged Magsafe connector or the two pronged one? Try using the three pronged one, it has a grounded connection. If you are using the three pronged one, then the outlet you are using my not be properly grounded.

Your computer isn't grounded. Make sure you're connecting to a grounded outlet through an adapter and cable that supports grounding.

I experienced this issue even with a three prong plug in the British Isles ... turned out that it was a mobile phone charger plugged into the socket immediately adjacent to the brick part of the MBP charger. I'm not an electrician, but I suppose that two transformers right next to each other is not a good thing (TM). I fixed it by just using the extender cable instead of the plug straight into the brick so that I could position the MBP brick part well away from any other electrical transformers.

HTH,

Boy, if I had a nickel for every time this topic comes up...

Yeah that happened to me when I had the charger connected directly at the power outlet. Now that I have it hooked up to an extender it's just fine.
