    I have a reasonably new 15" MacBook pro (April '10) and it just started doing 2 things...

    Firstly, a small metallic 'pinking' sound to the right of the trackpad appears from time to time. Tried to diagnose this sound but it is not a very reliable problem. Occasionally when the MBP is moved from one location to another but also when it is static on a flat surface and my hand is on the area to the right of the trackpad it appears.

    Now, a week or so later after the first problem appeared, the static electricity problem that has been reported whilst using a travel adaptor on on this forum is also happening. Are the two related? Do I need to worry?

    Many thanks in advance

    The metallic click you hear is most likely the sudden motion sensor i.e. normal.

    As for static electricity, I'm not sure what you mean. You can use the groudned plug...
