[QUOTE="skybolt, post: 1092127, member: 30261"] For a long time, I have had problems with the fan running on my late 2006 macbook. The fan will simply run, seemingly forever even when not under a load. I expect it to run when doing intensive work, etc., but it runs even when reading email and nothing in the background. I have tried all the suggested fixes -- SMC, PRAM, permissions, etc., but nothing has helped. I even took it in to have the tech look at it while it was still under warranty. He said he could not reproduce (can't understand that -- all I have to do is open iPhoto and the fan will start). We have cleaned the fan, etc. all to no avail. Now the crux of the story! For some reason I decided to take the battery out of the computer and run only on electric. No fan noise! I fired up several videos at the same time, started surfing the web, had lots of things open -- all with no fan running! To check another angle, I put the battery back in, but unplugged the electric. Got a "little" fan noise, but not nearly like I had been getting. So -- question is -- what is going on here? I have always left the battery in place and keep it plugged in to the electric. Should be fine. But maybe there is a reason the fan does not run when one or the other is missing? Would love for someone to explain what is going on here and why I am getting the behavior I am getting. Thanks for any and all input! [/QUOTE]
