Hi,

I know this is an old topic, but I couldn't find any acceptable solution anywhere. I am taking my MBP to Apple Store today, but thought I would discuss it here before I speak to Geniuses.

My MBP makes a low hissing sound above the left speaker when I connect my magnetic power adapter. I also hear the same from the brick in my power adapter. I have seen mixed response - some say its normal, some say its bad.

I am not sure about it, but does anyone else have this issue and did anything about it? What was Apple's response?

Thanks.
