Hi,

I noticed today that my new rMBP is emitting some strange high pitched noise, especially when doing heavy files operations like spotlight indexing or startup of the computer. It's louder and more prominent when I connect the AC adapter. It sounds like some power interference, a bit like some broken chargers do or Iphone 4s when transmitting 3G data.

 

 

It's not very loud but I can hear it clearly, when sitting in a silent room, even without closing my ear to the Macbook.

 

 

Has anybody noticed that or can advise something? Is that normal with those machines or some issue that has to be fixed? I really don't want to return it, as it is perfect otherwise...

 

 

Thanks in advance for feedback.
