After update, system will not stay asleep.

Exactly the SAME thing here...

Sounds like you are getting wake events from USB devices.

Try trashing the files at
/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
and
/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist

If you don't have an Autowake file, you can create one by scheduling a start in the Energy Saver prefs. Just make an event and then remove it.

Where I find this option in my MBP?

I'm getting this same message. I noticed it after my Macbook stopped going to sleep. Does anyone know if these are related issues and if there's anything to fix it? I've tried resetting the SMC and the PRAM but neither have worked. I bought the Macbook just a week after they were announced and this issue just started happening last night. Please help! Thanks

Hello, I had the same problem. Today I tried "going to sleep" again and it worked.

The only relevant thing I did today was installing the "iousbfamily327.4.0log.dmg" file downloaded from developer.apple.com (search for "IOUSBFamily.kext 3.2.7")

I initially installed the file "IOUSBFamily.kext 3.1.5" for Leopard 10.5.5 a few days ago. I also had problems when inserting a USB mass storage device (I got a "blue screen").

Now, after I installed the USB debug kit for 10.5.6, my MacBook Pro goes to sleep again. Please write if this solution worked for you!

Mine wakes up instantly, even after removing all my USB devices. Same console log message.

Just wanted to follow up to your post, this solved all my problems. I suppose we installed those drivers with similar intentions.

My computer is exhibiting exactly the same behaviour as this, even after reformatting and reinstalling 10.5 and then using the combo updater to 10.5.6. (In fact, it even did it on non-updated 10.5).

None of the solutions on this thread have worked for me.

I have no hardware connected to my Mac except for the power cord.

Hi,

I just found out that this problem disappeared when I removed the Xpress card (12-in-one) from Sitecom

Hope this will give some clues to others.....

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.

Some, in these forums, have had luck fixing sleep issues downloading the Combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
