New Retina Macbook Pro - strange whining Sound
Hi,
i just received my new Macbook Pro Retina - brilliant machine. But suddenly it starts to whine - I can hear the whining while sitting in front of the notebook, so its pretty loud. The sound does appear when I move windows or enter mission control. The sound disappears when I plug in the power supply. I made a recording: https://www.dropbox.com/s/oysfex8imnggefe/RMBP_whine.m4a
None of my Macbook's I owned before made such noises. Is my notebook faulty?
Thanks
