Hi All, I have a June 2010 17" 2.66 i7 UMBP. This is going to sound really silly and I do not really know how to describe it correctly, but it has begun to make lots of strange "Tapping/Clicking" noises. It happens quite regularly when the notebook is stationary but increase whenever the notebook is moved. I am familiar with the hard drive clicking noise but this is totally different - it kind of sounds like a small metal ball-bearing inside a small, thin glass sphere knocking or clicking against it's side or like tapping a small thin glass object with something like a thin metal rod. I am sorry for the poor description but that is the best way I can describe it & know I must sound like a complete idiot but I am not very savvy to computer issues but I hope someone can identify what these noises are if if they mean that something bad is going on. Many Thanks, Bazzy!
