I don't know if any of you remember but a few months ago, my unibody fryed and I asked for help on here, well in the end apple replaced it with the brand new 15 inch 2.8gh unibody, but now, this one is broke I think. It has started to make a strange clicking noise. The exact same noise and from the exact same location as the one in this video: http://www.youtube.com/watch?v=pXsKxhfc9Sg As well as mine clicking when you push down (like in the video) it also clicks whenever you move, if you lift it or tilt the screen. It also only starts to click when it has been turned on for about 15mins, basically, once it's warm. Does anyone have any ideas on what it is?
