I'm working on a solution to my S7's fan which makes a grinding noise every time I rotate the computer to the vertical position. When the computer is flat on a desk, the fan works just fine with minimal noise but when I recline and hold the computer on my knees, with the screen tilted vertical, to watch a movie, a grinding noise comes from inside the computer. I took off the back cover to diagnose the problem and it appears that fan #2 (the smaller of the two fans) rubs on the fan shroud when the computer is held vertically. Very annoying.
I contacted Acer's customer service (Indian call centre) which informed me that I would have to send in my computer for 10-15 days. I know what the problem is - the fan needs to be replaced but I can't seem to find any s7 parts available on ebay, etc. Installation takes under 2 minutes do I'm keen on doing the repair myself. Does anyone know where to get a replacement S7 fan or a shop that would be able to supply one?
And for those who are interested, Acer has employed a way to prevent self-repairs. The computer will not turn on with the back cover removed on the S7. A few of the screws are connected to a switch which prevents the computer from switching on with the back removed. Simply screw in the screws which have a small copper section on the board around the screw hole and you'll be able to boot the computer to diagnose your system issue.
