Loud Whirring/buzzing noise???
When I woke up my computer today, it starting making a very loud buzzing sound. I have a very new macbook pro with retina display that i bought in August in 2014. It's very irritating and loud, and I tried restarting it. the buzzing sound is gone when I turn it off, so it only makes the sound when its on or asleep. It seems to be coming the top right side.
MacBook Pro with Retina display, OS X Yosemite (10.10.1)
