Hi,
Panther is no longer able to put my iMac to sleep.
All was working fine till (approximately) several weeks ago. Can't think of any changes to this system during that time, other than--was it a security update a short while back?
Following advice offered in the Apple discussion groups, I've zapped the PRAM, repaired permissions, repaired the disk, experimented with settings in the Energy Saver panel, tried a different mouse, tried removing the mouse, and finally--reinstalled OS X. All to no avail.
This is not the most serious of problems, but just the same, I'd love to get back to trusting that this iMac will slip into a deep snooze if left unattended for a designated period.
By the way, what [does] happen, per the Energy Saver settings, is that the screen goes black. The fan, and presumably the HD, continue to spin.
I'd be most appreciative if you'd share your thoughts.
Thanks, JLS

Try disconnecting all network connections, sometimes a daemon can prevent sleep, especially if another machine is connected to yours.
You might consider trashing the file /Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
Reboot and see what happens.
However, if you reinstalled X and it didn't help it definitely sounds like a hardware prob.

Hi,
the same problem occured to me with my G4-ibook. It won't go to sleep except when closing the display or pressing the power-button and "S".
But i guess clearing the NVRAM could solve the problem. There are some tools out there to leave the ibooks awake even if the display is closed. Those tools apply some changes to the NVRAM therefore a clearing/reset should do the job.
I am still searching for a way to do this because the newer ibooks do not have reset-buttons anymore.
Best regards, Christian

I have a similar problem except everything shuts down but my fan keeps on running.
I removed my third party USB card; tried to ensure no background applications were running; disabled my Palm startup (as per Apple info board); run DiskWarrior; checked Permissions; zapped PRAM; rebooted...
.. and still the bloody thing won't sleep.
Come to think of it, this 'situation' only recently arose - recent Security Update(?) as you mentioned!

Has anyone tried to address this sleep problem by resetting the iMac's PMU? On the FP iMac's the button for doing this well hidden beneath the bottom cover, further hidden by a thin layer of plastic.

In my experience, automatic sleep has become very unpredictable since Mac OS X 10.3.something. Sometimes it works, sometimes it doesn't, and it even sometimes goes to sleep before the delay expires (I use 30 minutes).
I gave up on it.

Funny I too experienced that. It would go to sleep the first time after a reboot but thereafter not! Go figure.

Sorry to see that this is a fairly common issue. But, consensus seems to be: learn to live with it. I'll try.
Thanks for the feedback, JLS

Same here. I have an older G4 450 OSX 10.3.3 704MB RAM
It seems recently, that will sleep fine right after a reboot, but not thereafter. When I hit the powerbutton, dialog & choose SLEEP, it attempts to spin down, fans off and monitor blanks, but almost immediately reawakes.
If left to its own, it will go to display monitor sleep, but not the fans, CPU or hard drives.
I have a G4 933 which is sometimes doing the same thing. Both are running 10.3.3 of recent install/update. But it is more reliable to sleep.

The Energy Saver feature seems to be related to the USB problems I've been experiencing with my Mac. And since I applied Apple's latest security patch my wife's Mac (running 10.2.8) is also experiencing random keyboard/mouse failure. She'll go to her Mac and the display will be sleeping. She'll tap a key or move the mouse and nothing happens. Unplugging the keyboard and plugging it back in fixes the problem.
I've turned off all the energy saver features on my iMac and so far (a few days) there have been no keyboard or mouse hangs. I hope we're going to get an upgrade that addresses these problems.
