    Hi, would like to know if you guys have experience this before? I had the adaptor plug in to charge the MBP while using the laptop. I left it plug in even after fully charged. This is where I start to experience some static on the MBP. It's not like I got a shock but more like those numbing feeling. I am not sure how to describe it but it's like some kind of vibrating effect feel when your hands are on the aluminium body? Is this normal?

    i would get it looked at.

    if you have one, get a voltmeter hooked up to it and see if there is any charge

    Are you in a country that uses 220V? Are you using the grounded plug?

    Yes its 220V. I am using the charger plug that comes with the MBP plugged into a extension wire.

    the voltmeter should have 2 leads, take one and touch the body of the laptop where you can feel the tingling and ground the other lead (touch it to a metal table leg or something like that)

    if you get any positive or negative reading other than 0, there is a problem

    I have had this with all of my mac's, have even posted about this before

    I got it with my 12" PB, 15" Dual core and now my 15" uMBP

    It is especially noticable to me if I also touch the lamp next to my computer
    and likewise does not happen when it is not plugged in. Also being in UK, all of our devices are earthed.....
