Ok, so I have sleep problems with a 10.4.11 20" iMac I'm building here, and it just wont go to sleep on its own after the time defined in energy saving. Sleeps fine from the apple menu, wakes up fine in every case, and the monitor switches off with no problems.
So, this seems to be a pretty widespread problem caused by a numerous plethora of issues from what I've read over the last few days. Sometimes it seems to be caused by external usb devices, I can safely say this is not the case as there aren't any usb devices except for the keyboard and mouse. I can also says its not caused by having network connectivity as the symptoms are the same whether there is network connectivity or not.
Unfortunately, I cant be conclusive as to whether or not this particular mac ever actually went to sleep, I can only say that it was highlighted when I installed sleepwatcher and found that the mac was not actually sleeping at all.
In my book, I think the way forward is to start to try and narrow down the processes that are running that might be affecting sleep, so I ran up activity monitor and monitored disk activity on active processes. With sleep time set to 1 min, the time passed with apparently no disk activity, but the mac did not sleep. Same with cpu usage, same with network activity. I left the mac on all night, still didn't sleep...
At this point, I'm a bit stuck as to what to do next to try and narrow down exactly what is causing the sleep issues. I mean it must be a running process, so if I can find this process then I can hopefully find the root of the problem. Anyone have any ideas as to how to continue from here?
