Hi, I purchased my Powerbook (last rev.) in December of Last year. Its the 15" 1.67 ghz model, and I've been runinng temperature monitor recently, and its been getting into the 60-70 celsius range. It never used to be like this before, and the vent at the back is not BLOCKED is anyway. Is there any way that I can cool it down or shall i ring up Apple? I did drop my Powerbook like 5 months ago on the edge not flat on, but I'm 100% certain NO INTERNAL DAMAGE has been caused because of this. Please do help, my hands are sweating while writing this thread due to the heat coming from my Powerbook.
