G5 iMac Sleep Setting Won't Work

Message #1 - Posted 2008/09/03 - OldCSMAer

I can manually make it sleep by hitting command-option eject, or by using the Apple menu sleep command. It is set for sleep after 10 minutes in the Energy pref. pane, but it won't sleep. When I troubleshoot this issue, I am making sure there are no apps running that require a confirm command to shut down. Also making sure no wonky games are running that interfere.

This machine is the last G5 iMac...it has the Eyesight camera, 1 gig of RAM, and the latest version of Leopard. The Apple forums talk about a sleep issue with some G5 iMacs, but they appear to be earlier models.

Any suggestions? Thanks, as always.

Very often the cause is an application that prevents the machine from sleeping.

I don't think it's the Mac's fault - I agree that it is likely an application.
We used Eudora for years, last with the dual G5. It would not allow the computer to sleep - we always had to do it manually, as you do. You might try setting the sleep time down low, and experimenting with leaving only one app open at a time, to see which one is causing your problem.

Good idea, but just as a test, I tried it with no apps running and it still won't sleep. (I have tried the restore factory defaults in the pref. pane as well.)

How do you know that no apps are running. Try starting with the shift key depressed (safe boot) and then logging in with the shift key depressed (no login apps starting). Will it still not sleep?
