eMac Sleep Problems.

[dirtywheels]

I have an 800 mhz eMac with OS 10.4.4 installed. My computer will not go to sleep automatically. In system preferences/energy saver, I can set the display to sleep automaticlally after a set period of inactivity but the computer and the hard disks, when set for the same or slightly different time periods, will not go to sleep. When I start up in 10.3 from my external hard drive the energy saver funcitons work fine. Any suggestions? Thanks.

Are all applications closed when it tries to go to sleep? Open Activity Monitor, in utilitys, and copy the list of running activitys to these forums, then we can see possible programs that are stopping your computer from sleeping. Oh, and can you put your computer to sleep manualy?

Yes, I can manually put the computer to sleep. The computer will not automatically (set in Energy Saver) go to sleep with or without any applications open.
Thanks. Any other suggestions?

I am having a similar problem. I have a brand new (2 weeks) eMac with a 1.42 GHz processor and OS X 10.4.4 installed. After creating an Automator task (Power Tip Of The Month from Sept. 2006 MacWorld magazine, Turn Your Mac into a Musical Alarm Clock) the sleep mode stopped working. I can manually sleep the computer from the Apple dropdown menu but it will not sleep from the System Preferences/Energy Saver settings. This happened last week after installing a WeatherBug Lite application, which puts current weather conditions in the toolbar. Sleep resumed after removing that application. I have removed the Automator task and all startup items. Apple techs had me reset the Power Management Unit and trash the Power Management .plist from the System Management folder but this did not fix the problem. Any help will be appreciated.
