After I did the EFI firmware update and the my macbook pro restarted, I noticed that I started to hear a clicking noise from my laptop. At first, I thought it was a normal sound that I may have not heard before but I checked my other laptops and they aren't making any noise close to this. The other two laptops I checked were also early 2011 models, one 13" and the other is 15". Here is the recording of the sound. http://dl.dropbox.com/u/108564/iPhone/Memo.m4a There is some background noise but that clicking sound is the sound I hear. This is recorded with my 4S with the mic hovering around the palm rest and trackpad. I also noticed that when I tilt the laptop, I can hear a grinding sound. I tried to replicate this grinding noise on my other MBPs but I can't replicate it. What is the best option for me? If I take it to Apple, would they actually be able to replace it for me or resolve the issue? I don't want to waste my time driving 45 minutes to Apple just so they can say it's "normal". Has anyone had this issue before and taken it to Apple?
