Answer to: Why does pressure on left side of case cause fan to stop?Thanks for the help. I opened the case and noted that the left fan's green wire, close to the connector was doubled under the other wires. I hadn't given it much consideration, since the ambient light sensor cable, on the left side, comes up a bit high over a ridge. I checked the pictures on this site and that looks normal. So I had assumed that any pressure would be on the ambient light cable. However, I poked the left fan's power connector and cable a little bit with the spudger. When I applied power, with the keyboard still almost touching the screen, the fan rpm was 0. So that was with no pressure from the upper case and no screws in. I powered off, straightened out the left fan power wires properly and reattached the left fan power connector. I was able to reassemble the machine properly with all the screws. Problem fixed. Thank you for your suggestions. Regards Peter
