Not sure how many people have experienced the clicking noise replicated in this video: http://www.youtube.com/watch?v=mJmpervXe9M but I came across this "fix": http://tenonedesign.com/blog/fix-your-macbook-pro-like-a-champ/ and I was wondering if it has worked for anybody? It looks simple enough to do myself but it sounds pretty scary. What do you guys think? The clicking is driving me nuts!
