Powermac G5 dual 1.8, Mac OS X (10.4.3)
A number of sleep-related issues can appear after incremental Mac OSX updates, including the inability to properly go to sleep, problems waking from sleep, and having your display go to sleep without your Mac going to sleep. The most common culprit is Bluetooth. Try these tips to fix your sleep problems.
WAKE UP
In System Preferences>Bluetooth, uncheck Allow Bluetooth Devices To Wake This Computer. If you are using a Bluetooth mouse and keyboard, you'll have to wake your Mac by pressing the power button.
FILE CORRUPTION
Your Bluetooth preference file may be corrupt-you'll need to delete it. Turn Bluetooth off, then go to the /Users/user name/Library/Preferences folder. Look for a file called com.apple.Bluetooth.plist and trash it.The OS will create a new preference file when you enable Bluetooth again.
ENERGY SAVER
If you have issues with a Mac or display that goes to sleep at inappropriate times, you may have a problem with Energy Saver. Delete the following .plist files and restart:
-/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-/Users/username/Library/Preferences/com.apple.systemuiserver.plist--(username is your name or System Administrators name).
-/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
A restart is very important after deleting these plists. After a reboot your Mac will then generate new ones.
In some cases, running MacOS X's cron tasks-maintenance that the OS performs automatically if you leave your Mac on 24 hours a day-can resolve many sleep problems. If you don't want to leave your Mac on, you can use MacJanitor, Yasu, or OnyX free at Versiontracker.com.

Here's my other fact sheet on sleep;
This is for a Mac that won't sleep.
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.
If you've set your Mac to recieve faxes, it may not be able to sleep. It might also have a damaged preferences file.
If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Recieve Faxes On This Computer box.
If that does'nt work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!
Cheers!

Some have had luck downloading the 10.4.3 Combo update and installing it.
Your download may have something missing or have become corrupt.
If that does'nt work, post back.

My G4 PowerBook has been having trouble NOT staying
asleep for more than a few seconds and one of the
emails suggested looking at the Activity Monitor.
Apparently it's supposed to be mostly, or at least
partly, black most of the time. Not mine! It's
running not much of anything, but completely
red/green. It seems something called VShieldCheck is
using most of it. I tracked it down to Virex (I had 2
pre-Tiger versions installed). I used Spotlight to
look for all their files and then selected all,
trashed them, and emptied the Trash - and it's still
there!
I see you can use a "quit process" command in
Activity Monitor but it warned me that VShieldCheck
is "owned by root" and I'll have to use my
administrator function to get rid of it.
Should I???
