Computer will not go to sleep

I just installed Snow Leopard, upgrading from Leopard. Everything seems to be working fine, except that my computer will not go into sleep mode. Please help.

This is for a Mac that won't sleep.
Here is Apple's KB article HT1776 with their tips.
Mine follow;
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon 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 receive 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 Receive Faxes On This Computer box.
If that doesn't 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.
Some have resolved sleep issue by downloading the 10.6.6 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
USER TIPS……..
Check in System Preferences > Energy Saver is "Wake for network access" checked? If so, uncheck it.
One user reported, " I couldn't make my macbook pro to go to sleep because I had my wireless headphone receiver still plugged in. I unplugged it and then it went to sleep."
Also, if you have an External Western Digital (WD) hard drive and have installed
WDDMService and WDSmartWareD on your Mac, it may not sleep. Fix is to un-install those....you don't need them to use the drive.
"I have had this problem with my IMac G5. It is surprisingly irritating. LaCie's Silverkeeper backup software was the cause. By default it gave itself permission to wake up the computer to check if a backup was needed. Do you have this or a similar program installed which has scheduled activities including wake-up permissions as an option?"
One provided this link, xlr8yourmac.com, to a member, which addresses failure of deep sleep with some users that updated and added new FireWire and USB card.
Also, here is Apple KB article TA2469 about PCI cards and sleep.
After few days of messing around I found out that I had desktop background (wallpaper) set to change every 1 minute.
After unchecking "Change picture..." in system preferences (under Desktop/Screen saver), my powerbook went to sleep all by itself.
"I have a Canon printer(shared) and my imac would not sleep. I opened up printer/fax in system prefs and noticed it said the printer was in use when it was off. Opened up the printer queue and noticed about 7 pending documents. Deleted them all and now it sleeps.
Check the printer queue!"
One user has had success, after trying all these tips, using an App. called PleaseSleep. I've never used it though.
Good Luck!  DALE

Will not wake from sleep mode

When I close then open the lid on my MacBook, it will not wake up from sleep mode. I have to reboot by holding down the power button for 10 sec. When it restarts, it takes a long time to get past the gray screen with the apple logo. I also have this same problem when it goes into sleep mode, when left idle. I have since changed the settings so it will not go into sleep mode when idle in system preferences. I have reset PRAM and SMC, but the problem still persists.

I have the same problem, intermittently. I think it has something to do with full-screen mode, which I use intermittently. Have you noticed this happening only when you are in a full-screen app?
I also have a MacBook Pro from 2011, and I know for sure my MagSafe power adapter is fine and not part of the problem.
I have noticed a few things that may be hints at what is happening:
one time, (all??) while my screen was basking in the glow of sunlight from the side, I saw that the screen pixels were indeed "on", that the back-light of the screen was just off.
Which led me to the conclusion that my MacBook Pro was indeed waking from sleep, the screen was just not lighting up.
But that theory was disproved this morning, when when waking from sleep, the screen was black, except for my cursor. My cursor was completely visible on a black background. Huh?? It was like some software was putting up a black modal dialog over the whole screen. Also, the Apple Logo on the back of the laptop screen was fully lit -- meaning the backlight was on. The machine was awake (curson moving on a black background), and the screen was fully back-lit.
I'm not sure yet how consistent this behavior is... I will take more careful notes each time this problem happens in the future... But, it looks like I have rogue software that is trying to make my machine look like it is sleeping.
To "capture" the culprit I think I could set up a hot-key command that takes a snapshot of all running processes in Activity Monitor. This could show what processes are running when "waking" from sleep. nabbing the culprit?
I use Snapz Pro. That is non-standard software running with control over screen functions. Maybe Snapz Pro has a problem? I doubt it, but maybe, because it has hooks into background tasks with video. Snapz Pro is my only 32-bit process. Could Snapz Pro be the cause? I use Snapz Pro all the time.
The problem seems to be related to Full-Screen mode. Could it be possible that full-screen apps sometimes have problems returning from sleep? I know there are viewControllers responsible for handling events when waking. Could the symptoms of not waking from sleep be caused by bugs in full-screen apps?

MacBook pro 17" will not wake from sleep mode

Ok so my MacBook Pro 17" with osx 10.6.8 will not awaken from sleep mode. when attempting to wake it up the screen dosent come on and the mouse and keyboard do not receve any power. to get back on the computer i have to force a hard restart by holding the power button for 10 seconds then pressing it again. then it boots to where i left off when i closed the lid. i have read a few forums about this problem and i have went through all the steps of reseting various things and went as far as going into terminal using sudo to disable safe sleep and nothing helps. i noticed an unusual error in my console. here is a copy of my console log. the one in question is {7/14/13 4:52:43 AM com.apple.UserEventAgent-Aqua[118] dontAutoLoad = EMPTY!} someone please help me I am over 150 miles from the nearest apple store or authorised retailer

IPhone 1.1.4 will not wake from sleep mode

Hi all,
I have an iPhone with 1.1.4 firmware. The problem that I have is that the phone will not wake from sleep mode by pressing the "home" button. I have to press both the "home" and "sleep/power" buttons and hold them for 6 seconds for the phone to restart. I did restore the phone twice - did not solve the problem. Then, one day, I left it charging for about 3 days and when I came back it started working fine. Not for long though( After about a week of normal usage the wake up problem came back. I don't know what to do. I don't think it's the software problem, since I did complete restoration 2 times.
If the phone is connected to a charger or computer - it wakes up fine.
Thanks, Gene K

rimini,
When you've restored the iPhone, have you tried setting it up as a new phone? This would truly eliminate software as a possibility.
If setting it up as a new phone doesn't correct the issue, it's probably time for service: apple.com/support/iphone/service/faq/
Hope this helps,

Mac will not stay in sleep mode

My IMac running system 10.5.8 will not remain in sleep mode. I have tried closing all running applications and this makes no difference. After restarting the computer it seemed to function correctly for a short time then once again would not remain in sleep mode. The energy saver has no wake options set.

Here are 3 shots...of course things keep moving but I think I got most off.

My computer has been acting weird lately. Shuts itself off, the mouse goes off in all angles, does not go into sleep mode sometimes and instead shows on a gray screen definitions of words in 3" letters! Do I have a virus?

Doesn't really sound like a virus.
See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...
http://support.apple.com/kb/PH7029
How many of these you can answer...
Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
In the Memory tab, are there a lot of Pageouts?

TS3402 iMac with OS X 10.8.4 will not stay in sleep mode.

After installing latest OS updates, 10.8.4, we cannot get our iMac to stay in sleep mode. Energy saving settings have computer sleep and display sleep set to15 minutes, put hard disks to sleep when possible and allow power button to put to sleep are selected. Wake for network is not selected. Also allow bluetooth devices to wake computer is not selected. We are using Time Machine using a USB connected seagate disk, USB connected keyboard and bluetooth mouse. Sleep mode worked before applying latest OS update to 10.8.4 level, which was the only recent change. Now, if put to sleep, monitor goes black for a few seconds then back on. Appears that something that I haven't identified wakes it up.

The solution was found in another post. The suggestion made by marks33 says:
My computer would not stay in sleep mode either since update Mac OS 10.8.4 and I tried resetting the SMC.
Resetting SMC:
Shut down the computer
Unplug the power cord and ALL peripherals (mouse, keyboard + ethernet cable also)
Wait 20 seconds
Attach power cable and wait another 10 seconds
Press power button
Attach all other cables after desktop appears.
Try it if you haven't already. It cured the sleep issue on my iMac.

Are you ready : G4 MDD 1.25 DP FW400 will not go into Target Mode.

G4 MDD 1.25 DP FW400 will not go into Target Mode.....for migration assistant.
Shuts down every time I try either using "T" on startup or using the Boot Drive panel. G5 1.8DP I'm trying to migrate to shows up on the G4. Essentially, the FW400 ports are working in both directions as long as the G4 is not in target mode.
Ran Diskwarrior on hard drive
Reset PMU
Reset PRAM and NVRAM
AHT test passed
Moved hard drive from ATA100 to the ATA66
No data cables plugged in

Hi! make sure the G4 drive is either jumpered as the master drive and on the end of the ribbon OR if it's jumpered cable select that it is in the master position on the end of the ribbon. FWTDM won't work with the drive in the slave position. Tom

Safari will not work after sleep mode

After going into sleep mode safari will not work. Firefox works fine, mail is fine. Happened after upgrade to O S x . Browser is Safari 8. How do I fix this?

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

Why wont my screensaver activate, my computer will not go into sleep mode automatically.
