I was wondering if this issue is constant for you guys: I received my first mbp, and on the first day, when I was changing it from one wall socket to the other, the magsafe stopped providing power. I did the SMC reset as per applecare instructions, and was advised to swap for a new one, which I did. Today again when I was swapping it to another power socket the problem reappeared. I followed the troubleshoot guide at apple and let the magsafe unplugged for a few min, then suddenly voila its working again. So what do you guys think? should I pissed, and call for another magsafe, or this is something that I should be pissed and is a design problem with the magsafe itself?
