[QUOTE="Doug b, post: 947947, member: 59143"] Will do. I asked the tech in the store about the vibration issue, and he said it was "normal". Two possibilities here. One, is that he doesn't know what he's talking about. I don't think that Apple makes it a pre-requisite for their techs to be certified electrical engineers. The second possibility is that he didn't quite understand what I meant when I told him about the issue, and he just passed it off with a nod and smile. I'm inclined to think that it's a combination of the two, really. :Grimmace: The first thing I thought when I started using the MacBook Pro's here was that there might be a problem with the input voltage, but since the mag-safe adapter clearly states 100-240v 50-60 Hz, I was inclined to believe that I was being overly cautious and should just trust Apple with this. The other thing I forgot about though, is that I brought this particular MBP to Hungary last year, which was its first exposure to the different voltage. At my wife's mom's house, the vibration was really, really strong and it bothered me a LOT. I thought there was no way this could be safe. One other observation, and this is going to be very hard to explain in words: There is an intermittent sound which is emitted from the MBP. Sounds like it is coming from the left side. Happens while on battery or mains. The best way to describe this sound is that there's a tiny creature in there, with a tiny little ping pong ball, and every couple of minutes, he hits it and it makes a kind of "duhk" or "puc" (the uh is pronounced as look). Yeah, I'm weird.. I know. All I know is that if it is indeed a power thing, my Unibody is in big trouble ! Guess it's time to man-up on the Apple care for this one too.
