hi guys. I know there is a lot of talk about buzzing but I'm still unsure about my issue. I have a month old 2.6 15" MacBook pro. I recently arrived in Switzerland and had to deal with finding an adapter that I can plug my 3 prong extension cord so that's not an issue. But when I plug my chord in the transformer makes a whining buzz even if its not connected to the mac. When I unplug the buzzing continues for a bit and then the pitch rises and it ends with some sort of dadadada. Does anyone know what this is? I'm hoping its just the transformer doing its job because the voltage is higher here but I done know for sure and I don't want to hurt anything. Any info would be greatly appreciated thanks.
