Mac G5 Keeps Going to Sleep Because of Dust
February 21st, 2008
My Macintosh G5 kept going to sleep and I didn’t know why. I figured it must need some software housekeeping, so I checked the disk for errors and set the disk utility to repair any it found. Then I made sure the hard drives had plenty of space. I cleared room in my iTunes library. I uninstalled some programs I wasn’t using. In the end, I learned the problem was very physical. Taking out the fan, I saw the dust that had accumulated. This was despite running a hepa filter in the room. Vacuuming out the dust fixed the problem, which was that the computer was overheating.

How do you take the fan? Thanks for the tip am having the same problem.
