Computer will not sleep (EVER)

"When I close the lid the power light on the lid release goes bright but never cycles.
Also, my MBP will not "wake-up" from said state:
When I open the lid the light goes out, but computer does not respond. Closing the lid renews the light, but again, it does not cycle, nor wake up when opened again... The volume keys do however make noise when pressed.
Pressing "Sleep" in the apple menu is fruitless. It does, however, kill F12 to widgets, as well as the other special function commands F9,10,11 and such. It also prevents Apple-Tabbing (simply tabs), and swithcing tabs in FireFox by clicking them. Yet Tab+Up,Down,Left,Right works as should... But these symptoms are probably a result of a failed to-sleep routine."
This is really becoming a pain, and could use some help!
I am running the following system:
OSX 10.4.9
2.16 GHZ Intel C2D
2Gb 667 DDR2 SDRAM

Launch Terminal
Enter pmset -g | grep hibernatemode
It will return
hibernate mode x
Where x =
# 0 - Old style sleep mode, with RAM powered on while sleeping, safe sleep disabled, and super-fast wake.
# 1 - Hibernation mode, with RAM contents written to disk, system totally shut down while “sleeping,” and slower wake up, due to reading the contents of RAM off the hard drive.
# 3 - The default mode on machines introduced since about fall 2005. RAM is powered on while sleeping, but RAM contents are also written to disk before sleeping. In the event of total power loss, the system enters hibernation mode automatically.
# 5 - This is the same as mode 1, but it’s for those using secure virtual memory (in System Preferences -> Security).
# 7 - This is the same as mode 3, but it’s for those using secure virtual memory.
What is it returning ?
To set another mode use the command
sudo pmset -a hibernatemode x
If your machine was previously set to mode 3 (or 7) and you’ve reverted to the old style sleep mode, you’ve got one more step to take: recover the drive space used up by the copy of your system’s RAM, which was created the last time you slept the machine prior to making the switch. In Terminal, enter these two commands, pressing Return after each and providing your password when asked:
cd /var/vm
sudo rm sleepimage
I suspect the issue is related to the sleep mode set and the space left on your hard drive.

After installing recent java + security update, computer will not sleep

After installing the recent java, daylight savings, and the security update. my computer will not sleep. Does anyone else have this problem? I do have an adaptec usb2 card installed but nothing is plugged into it. Also i don't have any Ipods or external things plugged in. I have had the same setup for the past year with no problems, now it will not sleep. I have also tried repairing the permissions. Please help

When you select Sleep from the Apple Menu nothing happens, is that correct? Try this: Go menu > Home > Library > Preferences. Drag the whole of the Preferences folder to the desktop. Restart your mac, don’t worry if things look different, you have not lost anything. Can the mac sleep now? If yes, then its a damaged or corrupted .plist or preference. If you are using Apple Mail, drag the com.apple.mail.plist back to the new preferences folder created on reboot, you dont really need anything else but keep hold of the old preferences (the one you dragged to your desktop) just in case for a month or two. If everything else is OK you can safely delete it. If it has not cured the problem then remove the new preferences folder created on reboot by taking it to the trash, drag back the preferences folder you moved to the desktop and reboot. Now reinstall a clean OS. See how you go from there

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.
Yours would be the 10.4.8 Combo update. Others reading, download the combo update that applies to you!

My computer will not sleep, why?

When I go to the apple on the left and try to put my computer to sleep, it will not sleep. I have to press the power button for the computer to turn off. Also, when I turn it back on, it for some reason defaults to March 24, 2001??? Not sure what the problem is, please help!!!

Is the sleep issue a new problem, or has it always been this way?
What external USB devices do you have connected? Do you have a USB PCI card installed? Some USB devices can cause the sleep problem. Disconnect all external USB devices & see if the Mac will sleep.

15" MBP 2.66 8gb will not sleep ever-Same problem on two identical machines

I purchased the new 2010 MBP about a month ago. It never slept for me right from the time I first used it. This includes option-command-eject hot key, power button, closing lid, it will not go to sleep. All attempts result in the machine going into sleep for ~5 seconds and than waking back up.
I brought it into the Applestore and they ordered me a replacement computer. I received that replacement yesterday and after they did a data transfer and I took it home, it was doing THE EXACT SAME THING.
Any ideas?

These things are rarely really hardware related, tomthin. The problem is much more likely to relate to software installed on your computer which is making calls on the HD or the CPU, or to a peripheral attached to it.
Virus checkers, drive and temperature monitoring software, and network activity are common causes.
You can often get a clue by starting up Console (in your utilities folder) and looking at the console , system and kernel logs , esepceially at around the time you are trying to get it to sleep. Sometimes "Activity Monitor" can throw up some clues, too.
If you usually have anything physically connected to the computer at the time the issue occurs you should try disconnecting it, too. You might also try turning off bluetooth and wireless networking before putting it to sleep , to see if this makes any difference.
Is this a computer to which you have "migrated" things over from an earlier Mac using a an earlier version of the OS? If so, it is quite likely that a 'background" utility of some kind simply needs updating for the new computer.
Cheers

Computer will not sleep

I'm really getting agravated. For a long time my system OS 10.6.8 worked perfect. Now, since my grandson had "played" his Minecraft a couple weeks ago, it will not go to sleep or stay asleep. Any suggestions? I guess I need to reload the last time machine back up? Trying to figure out how to do that is mind blowing. Do I insert start up disk and use the DU on it and then pick restore from the icon of my external HD that time machine is on? I'm not too techy as you can tell

Intel-based iMac, Intel-based Mac mini: How to reset the System Management Controller

Computer will not sleep automatically.

Only sleeps if I close the lid or through the apple menu. Even with all apps closed.

Hello everyone,
Same here.
Had the same problem with 10.5.3 already. At that time, as I had lots of "beta" applications installed, I thought it might come from there. Then I also thought it might be Skype (if this application is on, does the OS consider it as an activity and never sets the computer to sleep? or is it the application itself that keeps the OS from putting the computer to sleep?).
Finally, last week, I completely reinstalled my computer (from scratch with the original 10.5 DVD). Upgraded to 10.5.4 and did all the Software Updates through the corresponding application (not by downloading the upgrades and installing them manually), Used Time Machine to restore my profile and reinstalled manually all the software that "want" to go in /Applications.
Yesterday, I had to download a big file, so I quit all the applications (including Skype), except Firefox (as I was downloading from there).
This morning, although the file was downloaded since long time, my MacBook was at the log-in screen, screen off, but not sleeping (the little frontal led was not oscillating as it is when in sleep mode).
Therefore, I don't think it is Skype after all.
What I haven't tested:
Create another profile and check whether it goes to sleep there. This could tell us if it is a profile related problem or an OS-wide problem...
If anyone has suggestions...
Cheers,
Pete

Mac Pro Snow Leopard Display will Sleep but Computer will not Sleep

Equipment:
Mac Pro Tower
Snow Leopard 10.6.8
30" Cinema Display
The computer has not been able to fully go to sleep since I bought it. (A refurb, but not from Apple's refurb store.)
As the title says, the display goes to sleep but the computer is still on. (Whether I select Sleep from the Apple menu, or with a keystroke.)
"Wake for network access" is not checked in the System Prefs.
I've disconected everything (inc. the monitor) from the back of the computer and the computer still won't go to sleep.
Reset PRAM and the "System Controller (the move where you power down, unplug the computer, press/hold the powder button for 5 seconds, plug in computer and start up).
I installed the PleaseSleep and the DeepSleep apps, but still no-sleep.
From Console, for the Sleep command:
11/6/12 4:51:32 PM
configd[15]
Sleep: Success - AC - Software Sleep
com.apple.message.domain: com.apple.powermanagement.sleep
com.apple.message.signature: Success

com.apple.message.result: Success
com.apple.message.uuid: A3270153-6D75-4639-8125-3B105B537BCB
Then from when I touched the keyboard to "wake":
11/6/12 4:51:32 PM
configd[15]
Wake: Success - AC
com.apple.message.domain: com.apple.powermanagement.wake
com.apple.message.signature: Success

"I was not able to use the system disks 'cos the image on the screen appears completly distorted and i am not able to navigate the menus."
Never ran across that type of problem on Apple's message boards.
"I have temporarily fixed that using a ten days trial version of SwitchRes X. Everything works fine now but the Display preferences panel from MacOs, wich stays "in coma"."
In that case, are you now able to boot off your install DVD? If so, run the +"repair disk"+ option, when done boot back to desktop & run repair permissions.

Hello, Lance.
Have you checked your System Preferences... > Energy Saver settings?
Specifically, are any of these items checked:
• "Wake for Ethernet network access"
• "Startup automatically after a power failure"
• and these System Preferences... > Energy Saver > Schedule sub-menu settings:
• "Start up or wake"
• checkbox with "Restart" in Sleep/Restart/Shut Down choices bar

Will not sleep after OS 10.9.4 update

Mac Pro 2013 will not sleep, either manually or through Energy Saver. It sleeps for about 2 seconds, then back on. It worked fine before the update!

Test after each of the following steps that you haven’t already tried:
Step 1
Take all the steps suggested in this support article. That's the starting point for any further effort to solve the problem. Skipping any of those steps may mean that the problem won't be solved. Note that, as stated in the article, the computer will not sleep if Internet Sharing is enabled.
Step 2
From the menu bar, select
           ▹ System Preferences ▹ Accessibility ▹ Speakable Items: Off
Step 3
Select
           ▹ System Preferences ▹ Bluetooth ▹ Advanced...
and uncheck both boxes marked
          Open Bluetooth Setup Assistant at startup if...
Step 4
Reset the SMC.
Step 5
Disconnect all wired peripherals and test. If you use a wired keyboard and/or mouse, use different ones. You must rule out the wired keyboard and mouse as possible causes of the problem.
Step 6
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, 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.
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.
Safe mode is much slower to start and run than normal. Don’t launch any applications at first. If sleep still doesn’t work properly, back up all data andreinstall the OS. After that, if you still have the issue, make a “Genius” appointment at an Apple Store to have the machine tested.
If sleep now works as expected, go on to the next step.
Step 7
Still in safe mode, launch the usual set of applications that are running when you have the problem, including your login items, one at a time, testing after each one. Some applications may not work; skip them. You might be able to identify the cause of the problem this way.
Step 8
If sleep is still working after you’ve launched all the usual applications, restart as usual (not in safe mode) and test again. If sleep still works, you’re done, at least for the moment.
If you still have the sleep issue after restarting out of safe mode, post again.

IBook will not sleep

Since upgrading to Tiger, now when I close my iBook lid, the computer will not sleep. The only way I can get it to sleep is to unplug all peripheral devices (including my power cord) and select sleep. It used to sleep automatically on closing. I've tried adjusting my energy saver choices in System Prefs, unclicking receive faxes in System Prefs, and all other funky suggestions I found online but to no avail-it will still not sleep when I close the lid. Does anyone have more suggestions? I travel a lot and like to store my computer in sleep mode in my computer case, but now it runs instead and wears my battery down!

Hello,
Unfortunately, I think your problem is hardware related. From your logic board, running through the right hinge of your display, there is a cable that is connected to your display inverter board, and a device in the display, called a reed switch. This cable contains several wires (6). The reed switch is a device that, when nearby a magnet sets the computer to sleep. The magnet is positioned underneath the keyboard so that when the lid is closed, the computer is set to sleep. If a wire is broken (most likely in the hinge), you may have one of several problems. For example, your sleep function will not work. Or, as in my case, the backlight does not work, so the display goes dark. Only time will tell which cable will break first, so in your case it was the one to the reed switch.
What you need is a 076-1073 PCEBA Reed Switch with Cable for
dual USB white iBook. It is an original Apple part and can be purchased from http://www.smalldog.com for $20. However, replacing the cable is somewhat tricky, but not impossible. I did it without previous laptop surgery.
There is also another discussion thread on the backlight issue. It has some good links.
This is what I think is the problem.
Good luck

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

After using Time Machine-Computer Freezes on startup and will not sleep.

I've narrowed down my iMac issues to Time Machine.
After I back up with Time Machine, my iMac freezes on start up ( I have to turn it off and turn it back on again for normal start up) every time I turn it on and it will not sleep.
I reset the SMC, startup in safe mode, and do all of the troubleshooting to get it back so it starts up without freezing (sometimes my troubleshooting works). I've even reinstalled SL a couple of times and that seems to have helped but...
...when I back up with Time Machine, the freezing issues and non-sleeping issue return.
I've just installed the 10.6.2 update and my iMac is now working perfectly, no freezing on start up and it sleeps.
I'm afraid to use Time Machine for fear of the problems returning.
Any ideas on why Time Machine would corrupt my system? Any thoughts on how I can remedy the situation?

Hello m:
The preference file (plist) tells OS X what default and/or user preferences to apply to a device or a program. They rarely become corrupt, but if they do they cause all sorts of odd behavior.
After you trash the preference file and restart, OS X will rebuild the missing file with default values. If you have some personal preferences, you would need to enter those.
Barry
P.S. The preference file I mentioned is located in Macintosh HD>library>preferences

HP Envy Will Not Sleep Automatically

My computer will sleep fine if I tell it to, but it won't do it automatically. That function is critical to my computer's security.
I confirm that I've told it to sleep after 1 minute, whether on battery or plugged in. If I tell it to dim the screen after a minute, that works fine, but it will not sleep.
Below is the Power Efficiency Diagnostics Report (Forum removed HTML) -- note the errors.
I have unplugged all USB devices. I have stopped the WIndows Media Network Sharing Service. I have disconnected from the network (airplane mode). It still will not sleep.
Please tell me what else to try.
