Hi, My computer is working fine except sometimes I cannot make it go to sleep. I hear a noise that seems to come from the fan, I assume is the fan because the computer works perfectly fine. The sound is like a motor been tired a constant sound like and rrrrrrr..rrrrrrr.rrrrr. Any suggestions where the sounds it can came from? Thanks, Mia
I’m not too farmilier with this mac, but it looks as if it’s overheating (Or at least thinks it is). Have you removed the processer heatsink cover, and checked for leakage from the Liquid Cooling Unit? (This was only there in later dual, and quad models) try remoiving the cpu’s, and cleaning the dust from the attached heatsinks.
Hi This is Ejaz. The Mac will not go to sleep and make those sound,if you are using 3RD party memory. Because on some memory chip,sleep controls only works only PC platform not on MAC. Mind you not all memory are totally compatible with MAC. Thanks EJ
