I have tried it in many sockets in the house and it is always there after a fe minutes of being plugged in. It actually builds over time.
Anyways apple are taling it back and I am getting a refund, was thinking that I should have gone for the 17inch version anyways only downside is it could be acouple of weeks before I can order the new macbook pro
I have a 17" MBP, and my 1 regret is i didnt get the 15"... Also, i have the same problem with the electrical charge... sometimes ive even gotten a bit of a jolt at my wrist when i have 1 hand on the mixer and the other on my laptop...
I thought it was my imagination for a long time, im glad to know its not just me... ;-)
It hasnt been a problem with the performance of the computer so i guess i will just leave it... Ive had this laptop since Feb of 2007.
