    My MBP powerbrick I've noticed in the last couple of months hisses. When I fire up an application (like iTunes), the hissing intensifies slightly. I only really hear it because I have good hearing but I DO HEAR IT!

    Is this normal? This is the powerbrick from my SR MBP I bought in October. I currently have the Penryn MBP but it hissed with my other (original) machine too...

    Yeah, some adapters make a little noise especially when under a heavy load. It's not something to be alarmed about unless you notice the adapter getting really hot or the noise intensity increases. If you're still under warranty you might stop by the local Apple Store and get a replacement.

    Is this a defect or is it "within spec"? Why do some make the noise and others don't? Should I get it replaced?
