Hi All, I'm in Switerland right now, and I have a question about the power supply for the Macbook Pro. I know that the power block can handle 100-240 Volts of input, so I'm not hurting the computer by not using a converter. However, when I have the computer plugged into the power via the magsafe, the whole case of the computer feels like its holding a current. The palm rests vibrate slightly when I move my hands across them, the back of the screen especially feels strange when i touch it. All of these things happen not only when the computer is on, but also when it is asleep or off and charging. Obviously, when I touch it with more than one hand, the buzzing feeling stops because I am grounded, so the current (if thats what it is) has somewhere to go. Has anyone else had experiences with this happening? Is it just because the Pros are not made to exactly work with the 220 V? Is there something wrong with my power block? everything on the computer works normally, and I have not had any issues with screen flickering, power outage, batteries exploding... or whatever. Thanks in advance.
