Electric shock from MacBook Pro while charging only.

I get light tingles from the side of the chassis when it's connected directly to the mains. Same sensation as pins and needles, but in the wrists. I love it! Sometimes I just sit there for hours letting it pass a mild current through my body. I'm not too cared about my body, but do you think this could harm my MBP?

I have the same problem and get stung all the time. My wife refuses to use the computer. I can also hear a slight hum in the audio output of the internal sound card. I have detected the hum using my Beyerdynamic reference headphones, Zenheisers and speakers. The hum goes away when I have my hands on the case and returns when I take them off. I'm going to the iBox tomorrow and will show these posts and hopefully I'll have this machine replaced.

So far I have had the keyboard replaced due to paint flaking, the machine has died on me due to a faulty logic board, the screen is slighthly bent (similar to this one http://www.appledefects.com/wiki/index.php?title=Image:Macbookprowarp.jpg), screen replaced due to a hair stuck in the sceen and lastly the mag safe cable connector was replaces due to frailing. I was hoping apple would have higher quality products.

I too have this problem. In my house in the UK using the two prong lead I get shocked wrists, humm/buzz sensation at my house. Never noticed it at other locations (uni, work etc) so I believe it is also dependent on the electricity supply in your house.

As you say, it might have to do with the electric supply but a piece of equipment worth USD 2000 should not give any kind of shock. My wife has a macbook and due to the plastic casing it never gives her any shocks only blisters from the sharp corners of the casing. Rather that though that elcetricity zapping you.

Not sure why the UK plug that fits onto the brick doesnt have the earth pin connected like the UK extension lead does. Oh well, at least I know my mac isn't faulty. And I need to have my house electrics looked at!
