Snow Leopard Sleep Issue

I did a clean install of Snow Leopard on my iMac and now whenever i use expose and put my display to sleep or enable the screen saver or put my computer to sleep the computer will do those for about 15 seconds and then turn back on, i will leave it for an hour and the screen saver will never come on or put the display to sleep or the computer to sleep, I have the screen saver set to come on in 5 minutes and the display to sleep in 30 and the computer to go to sleep in 1 hour. I have turned the wake-on-lan off even. Computer will not go to sleep.

MacBook Pro, Mac OS X (10.6)

I have followed your directions for HD/Library/Preferences/SystmConfig/ and have no com.appleAutoWake.plist in that file.

I found the answer in my case. I looked in Console and found a widget that was constantly looking online. After deleting it I`ve had no more problems. maybe that could help others. Check in console for apps or widgets which constantly appear.

I had this problem and fixed it by unchecking the following:

System preferences/energy saver/wake for network access

My display does not sleep when it is showing the login window. Sadly, the lovely 24-in display is growing a ghost of the login window.

As I recall, it used to go to sleep automatically from the login window. I now have resorted to causing it to sleep by clicking the button for that function on the login window.

I've tested alternative settings (from two different accounts with admin privs). I've looked for and not found any alarm settings in the system. I've reset PRAM repeatedly. I've reviewed the plist settings for power management, making sure that my changes to the settings were writing to the file.

In the system log, I do not find entries regarding sleep. For example, from the system log for my Mac Book Pro, I have "configd[13]: Sleep: Success - AC 95 - Idle Sleep"; there are no comparable entries in the log for the iMac.

Wit's end... a maze of twisty little passages, [many] alike.

I've not had a chance to trouble shoot this, but now it appears that something's apparently hosed (pardon the technical language) with sleep on my account. As I walked toward the door of my office this AM, I noticed a lot of light. Sure 'nough, the screen was in the condition where I'd left it 8 hours earlier. Sigh.

My Macbook Pro (Intel) was doing the same thing. I've been trouble-shooting it for a month now until this morning I discovered the same thing regarding the screen-saver that was hanging on a photo folder in iPhoto. I just changed it to one of the stock screen savers and it seemed to solve the problem. I was just going to post my discovery when I read yours.

So... +1 😉
