Automatic Sleep solved

Hope this helps someone
For several weeks the G4 would not go to sleep automatically per the settings in the energy saver pane. Trashing plists and other remedies suggested in this forum did no good. I could put the Mac to sleep without problems including wakeup.
The problem source showed up as an active process "TCC" in the system utility "Activity Monitor." TCC was installed as a maintenance utility download about the time Sleep became a problem. The "Activity Monitor" has a process force quit (kill) feature. TCC could not be quit. This suggested that maybe TCC was running constantly or automatically always restarting to perhaps check the internet.
TCC can be run automatically for certain requirements. The menu has a disabling command for automatic run. Disabling automatic removed TCC from the Activity Monitor. At the same time the Mac automatic sleep worked. Coincidental?

TCC are the name initials of one of the fine Mac only maintenance and troubleshooting utilties available, namely Tiger Cache Cleaner. TCC is actually what showed up on the Activity Monitor, as reported in my previous post.
I purchased and downloaded it.
Hope this answers your concerns. But if not ask away.

I can't seem to get my iMac (late 2009 model) into automatic sleep mode. If I manually put it into sleep I don't have any issues. I used to solve the issue by running "PleaseSleep" application but that doesn't work anymore since Lion.

I can't seem to get my iMac (late 2009 model) into automatic sleep mode. If I manually put it into sleep I don't have any issues.
I used to solve the issue by running "PleaseSleep" application but that doesn't work anymore since Lion. I now want to fix the underlying problem.
I'm not running any weird background processes and in my energy saver settings I've tagged "put the hard disk to sleep when possible:, "allow power button to put computer to sleep" and "automatically reduce brigthness". All pretty standard.
Is there anyone who can give me some pointers ?

Today I solved the same problem for my iMac running Snow Leopard. See https://discussions.apple.com/thread/3008791#15947706. The method may help you, too.
For me it was the DynDNS Updater preventing my iMac from automatically entering sleep mode.
To my knowledge the cause of this sleep problem can only be a peripheral device or a process. So I suggest to first unplug all peripherals and test whether that's the cause. If not, I suggest to terminate one process after another and to test automatic entering of sleep mode after each. Start with user processes; continue with system process if necessary.
At least that's the way I found the offending process. Fortunately, I was able to change the configuration of that process to allow again automatic entering of sleep mode.
Good luck!

Snow Leopard 10.6.8 automatic sleep issues

Hey,
I have a 27" Apple iMac with an i5 processor and 8GB of RAM running Snow Leopard 10.6.8. I have had it for about a year and a half and for the first 15 months or so it was perfect. However in the last few months I have been having problems with automatic sleep.
When the computer was working correctly if I had set the display to sleep at 5 minutes and the computer to sleep at 15 minutes in energy saver, then if the Mac was idle it would sleep at these times. If however I was say printing a lot of pages or downloading a large file or ripping a DVD, then the computer would not sleep even if the 15 minutes had elapsed but once it had completed its task and 15 minutes had passed, it would sleep. This was great if I was leaving home or going to work as I could rely on my Mac to finish its task and then sleep and so not waste electricity.
So when the problems started, first my Mac would never sleep automatically and this was for a while fixable by simply clicking "restore defaults" in the energy saver settings. Then no matter what it would never sleep unless I set it to sleep manually and now after trying a solution from Apple care (restoring disc permissions in disc utility), the Mac sleeps once the prescribed time has elapsed no matter what I am doing be it listening to iTunes, downloading a file and so on.
In other user accounts this problem also abounds and so doesn't appear to be related to third party software. On the recommendation of an Apple care guy I reinstalled Snow Leopard from disc (the lesser install that does not erase the hard-drive and takes about 45 minutes) and after this the sleep function was working properly. However as soon as I updated the Mac to bring it up to date after the re-install, the problem started again. This gives me the impression that some update from a few months ago is causing this issue.
According to the Apple guy, there is no known solution for this and he tried to sell me a load of nonsense about using third party freeware like caffeine and please sleep to solve the problem. However these solutions are useless unless you are around to ultimately put your Mac to sleep manually and/or turn on/off the third-party software.
This may not seem like a big issue, but when I have my Mac perform many tasks while I am not present, if it stays on indefinitely afterwards, then it is really wasting a lot of electricity.
Has anyone else had this or a similar issue and found a solution? I know I could upgrade to Lion and try that, but if that doesn't work then I will have wasted €24, plus I was hoping to wait until as many of the kinks had been worked out of Lion via patches before updating.
Has anyone had any experience with trying to get Apple to replace a computer that is still under Apple Care warranty over a year after purchase as if it continues, my Mac has lost a LOT of its functionality for what I need it to do and I am no longer happy with it.
Thanks.

Your post is pretty lengthy and I have to admit I didn't read it all. Please try restarting in Safe Mode, if that doesn't work please do both a SMC and PRAM reset. These may take 2-3 attempts.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

MacBook won't automatically sleep

My MacBook won't automatically sleep anymore. If I close the lid or command it to sleep, it will. But it will no longer automatically sleep. I've tried tons of fixes and searched for hours on the internet, but still have not found a solution. I seem to have noticed that this starting happening after I installed Windows XP via Bootcamp, so I'm guessing that the problem is related to that. Any ideas?

This is for a Mac that won't sleep.
Here is 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.
Hope this helps!
P.S. One member here reported this (Michael Gleason);
"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?"
Dave Hamilton 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.
tomhorvat adds this; 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.
Tristan Currier noticed this; "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!"
Allan Jones says "sometimes there is Network activity: launch System Preferences > Energy Saver > "Options" tab and uncheck "Wake for Ethernet network administrator access."
Good Luck!  DALE

G5 will not automatically sleep.

I have read other posts but none seem to fit my scenario. I have a G5 with 2 internal drives both running 10.5.8. My main boot drive will not sleep when scheduled only when I select it from the menu or press the power button. The other drive will sleep with no issues. Is there a way (without having to clean install and re-install all my preferences/programs) to replace the energy saver prefs for the drive with the issue?

I have exactly the same problem with my G5 tower.
Choosing sleep from the apple menu and pressing the power button work fine, but automatic sleep in Energy Saver prefs does not work.
Like xshedx, I have tried resetting the PRAM and SMU. I've also removed RAM chips and this weekend I replaced the stock Apple internal hard drive (160GB) with a WD 500GB Black Edition.
Even after I did a fresh install of Leopard (leaving it on original 10.5) and recreating my user account from scratch......it STILL won't go to sleep after a specified amount of time.
So it seems like it's not a system update issue, as I'm running 10.5 with no software updates applied.
It must be an internal component and I'm officially out of ideas....

Won't automatically sleep with energy saver

Brand-new iMac will not automatically sleep, but will sleep on demand. Display sleeps, but hard drive stays on.
I'm not completely computer-savvy, but I've searched through other threads regarding this issue and tried the following:
- deleted com.apple.PowerManagement.plist
- reset SMC
- tried with a new admin account
- reset PRAM/NVRAM
- disconnected peripherals
- repaired file permissions
- Bluetooth settings: changed to not discoverable, turned off bluetooth sharing. I still need it on though bc my KB and mouse are wireless
Not really sure what the Console/system log stuff is, but I looked in there and saw this over and over:
+May 23 09:43:45 greatwhitehope com.apple.launchd[1] (com.google.keystone.daemon[394]): bootstrap_register() erroneously called instead of bootstrapcheckin(). Mach service: com.google.Keystone.Daemon+
+May 23 09:43:45 greatwhitehope com.apple.launchd[1] (com.google.keystone.daemon[394]): Exited with exit code: 1+
+May 23 09:43:45 greatwhitehope com.apple.launchd[1] (com.google.keystone.daemon): Throttling respawn: Will start in 10 seconds+
So I turned off Google Notifier. Didn't work.
It works with Please Sleep... but I just got this computer and it kind of ****** me off that it won't auto-sleep.
Can anyone please help or offer other suggestions?

I have the same problem and I've already contacted Apple about it. We've tried the same solutions as listed above and some more. Finally I had to record my system info during the problem (with Capture Data) and I've sent it to Apple.
The good news is that they know the problem and they are working on a solution.
The bad news is that I've bought my computer in February, I immedeately reported the problem, and there does not seem to be any progress. I contacted Apple again early May and they told me I should wait
I'll try the Sleep apps that are suggested above because it's extremely irritating the have your computer awake with fan and all when you want to sleep yourself.

Automatic sleep broken after 10.5.7 update

Hello,
Since I updated my 10.5.6 system to 10.5.7, the automatic sleep function doesn't work anymore. Screen goes black but harddisk keeps running (little light doesn't pulse).
I tried to repair permissions, reset SMC like described elsewhere in the forum, without any success.
Finally, I reinstalled 10.5 using the "Archive and install" option. Then applied the 10.5.6 combo update. And automatic sleep worked again.
After a few days, with the coming of Safari 4.0 final version (which only work with 10.5.7...), I decided to give it a try and applied the 10.5.7 combo update.
And guess what...
Automatic sleep is broken again...
If anybody has a solution, I would be happy to read it.
Thanks in advance

Some clues point to my external LaCie DVD±RW DL...
As long as it is connected to my MacBook, automatic sleep doesn't work. A green light is flashing at regular intervals, which indicate some sort of activity that could prevent the MacBook to sleep automatically.
To confirm this, I disconnected the external burner and... automatic sleep was working again. I checked the availables updates on LaCie website, but it seems that my burner's firmware is up to date.
I've sent a support request to LaCie, hoping they could do something about it.

Aluminum PB Won't Automatically Sleep

I posted this before, but said Titanium when I meant Aluminum. So I've posted again with the correction.
My 15" Aluminum Powerbook won't automatically sleep any longer. This seems to coincide with my upgrade to 10.4.2, or perhaps the recent AirPort upgrade. (I'm not totally sure.)
While the computer will not actually go to sleep automatically, the screen, however, will go black -- but the sleep light doesn't actually come on..
To fix this, I have tried:
1) Resetting P-RAM (command-option-P-R)
2) Resetting Power Manager (battery out, AC power out, hold power button for 5 seconds)
3) Disconnectting AC power and removing battery for 30 min. to reset computer internals.
4) Repairing Permissions
5) Booting up, don't start any apps, and waiting for sleep.
No matter what I do, the computer will not automatically go to sleep.
Any help appreciated.
Best,
Mark

I've been having this problem for a while now; in fact, perhaps since after 10.4.2, I would reckon.
This is quite an important thing, as I do a lot of work on site with my Powerbook, and it is very inconvinent when I run out of battery. However, bringing this up on these message boards can give people the impression that you just don't know what the "Energy Saver" function of System Preferences can do!
Does anybody have any tips for identifying processes that run in the background? I've been looking at the terminal command top, but not really finding anything. It does tell me how many processes are running, however.

Automatically sleeping a MacBook Air prior to battery reaching zero..?

Hi, does anyone know if there is a way to automatically 'sleep' a MacBook Air before the battery runs out?
I'm usually pretty good at plugging it back into the mains before it 'dies' but twice recently I have missed the warning for a low battery and it has 'died'.
There must be a setting or an app out there that will 'sleep' the laptop when the battery gets to a specified battery percentage or time remaining.
Btw, I have a late 2010 13" MacBook Air running Snow Leopard.

Tried hibernatemode to 25 and still not helpful at all.
Battery drained 8% after 10 hours of sleep while mode 25 should put my macbook air into deep sleep and consume very minimal power.

Automatic Sleep Not Functioning

I have read the other posts on this topic. Unfortunately, nothing in them has helped, and it seems that everyone else's problems have been fixed by various things posted in those topics. Here's my problem:
My MacBook Pro will not sleep automatically, no matter where I place the sleep timer. I have tried quitting all third party apps. I have checked the Console, and I thought I found the problem there. Apparently Mozy (a backup utility I had previously deleted) was still being attempted to run every few seconds by some helper deep in the system. I ran the uninstaller, and that stopped, but still no automatic sleep even after restart. I thought it was Connect 360, but I disabled that and confirmed no processes related to it were running, and still no automatic sleep. I tried disabling Spotlight. Still no auto sleep. I tried disabling Time Machine. Still no automatic sleep. I'm getting incredibly frustrated.
Manual sleep works just fine. This problem did not happen under Tiger. My Leopard installation was clean. Please, any help on this matter that hasn't been covered in other threads will be very, very appreciated.

Ha! No answer to your question. I have the same problem. Computer simply doesn't go int sleep mode as set in the energy saving prefs. Seems to be a real bug! Why does Apple not react?

Automatic "Sleep" Functional for Anyone after 10.5.2?

I'm wondering if anyone's "sleep" works after 10.5.2? If it does now, but didn't at first, what steps did you take to correct the issue? Is this failure-to-sleep problem restricted only to Intel-based systems?

Hi Daddy,
I do not wish to appear offensive... but you've still not told me if you have an Intel-based Mac with OS X 10.5.2. Details at the bottom of your post do not clarify this issue!
I would like to know if anyone with this configuration now has a perfectly functioning automatically timed "sleep." This question has either a "yes" or "no" answer. I am particularly interested in hearing from those who experienced an unresponsive automatic "sleep" after upgrading (i.e., an initial "no") who have subsequently found a "fix" that reinstates a functioning automatic (timed) "sleep." If no one in this category responds within the next day or so, I'm obliged to infer that all Intel-based Macs (and possibly others) most likely experience this problem after updating to 10.5.2. +I view this as a truly minor inconvenience as I remain able to put the computer to sleep manually.+
However, I have acceded to your request: I dismounted both FW drives (physically and electrically). The Mac was rebooted with no open applications --- the monitor shut down at the specified time (after approximately 10 minutes of inactivity), but the Mac *+did not+* go to sleep even after waiting another 15 minutes beyond the specified time! I still have not tried booting with an unplugged USB keyboard/mouse...

Automatic Sleep modus

Hello. Well I have my iMac G4 now for 3 or 4 years and I'd never had this problem, but since I have 10.4.3 it started. Well, the automatical Sleep Modus is activated to save energy. But the problem is, that the screensaver apperars after 5 minutes, like normal, but after the time i want the sleep modus, the computer does not go into sleep modus. I hope someone can help me, because the preferences are fixed well and normally the iMac has to sleep. But it doesn't work anymore. Is it the system or the computer it-selfs?

I did install: new intel chipset drivers, but the problem = still there
I tried to install de ATI AMD drivers, but this will not update the display driver version.

No Automatic Sleep in Leopard

Auto sleep was working just fine in Tiger, but no-go in Leopard. Anyone getting Leopard to automatically sleep?

I discovered the cause of my Mac not auto-sleeping. I have a Firewire drive connected that I was using for Time Machine. I've used this same drive for automatic nightly backups with SuperDuper for about the past year, before I started using TM. When I tried to dismount the FW drive to test if that was my sleep problem, it said I couldn't because the drive was in use. OK, so I switched TM to OFF, and still it said it was in use. TM should have been the only thing using that drive, so I'm puzzled why this happened. Anyway, the only way I could free up the drive and dismount it was to reboot and try again. Only after that could I dismount the drive, and an hour later the computer went to sleep by itself. (I suspect that TM leaves a file open on the FW drive even after it is stopped.)
I still need to find a solution for using TM and auto-sleep together.

Why won't automatic sleep work on a Macbook?

My macbook goes to sleep fine when I close the lid. I have no issues putting it to sleep using the menu command, but it will not go to sleep on automatically. I had this problem in 10.4 and it has continued under 10.5. I did a clean install a week ago, carefully making sure after every application that automatic sleep would work. It did, though it usually took 1.5x as long as specified in the energy saver.
The only non apple apps I have are: Office 2004, STATA, Gimp, Handbrake, and Poker Academy 2.5.
So, last weekend having made sure everything was working, I moved my files back on to the computer. The only preferences I retained were those in the iPhoto and iTunes folders, my Safari bookmarks, and my address book and iCal files.
Now, one week later my Macbook will not go to sleep. The same thing happened after I started using this summer, only I didn't go to the trouble of testing sleep as I installed apps. I just noticed one day that if I left the lid open it would never go to sleep, regardless what was plugged in, energy saver settings on anything else.
I asked a Genus about this and was told it was a Software issue. I tried very hard not to be mad. This is my fifth apple laptop (two from work) and none of the others have had this problem.
Anyone else having this problem?

It most likely is a software issue ...to confirm this try booting into 'Safe Mode' and seeing if things resolve themselves. If they do, then it may be certain 3rd party software that is preventing sleep.
If not, then it may be a hardware issue - in which case you'll have to bring your book in to an Apple Tech.

After ram upgrade automatic sleep is not working anymore

Some days ago I installed a second 1GB ram module in my 20" Intel iMac. After this I noticed that the automatic sleep do not work anymore. The display turns off but the iMac not. The iMac makes sounds like he wants to do to sleep but could not.
I tried everything I could find... delete OS X powermanagement prefs, run Onyx, reset the SMC.
Do anyone have an solution for this?
Thanks

Does your iMac recognize the new memory module?
Yes.
You might try reseating the module in its slot, and it
would not be a bad idea to run Hardware Test from
your install/restore DVD, just to be sure there is
not an underlying hardware problem.
Already done - no problems reported
Is your new memory module of the same specifications as the
stock module?
Yes it is the same, I had a look on this before I bought it because I wanted to use the dual-channel mode.
Also, what are your settings for sleeping your iMac?
5 min to sleep display, 10 min to sleep the mac
One other thing you may wish to
try is updating your system of OS X 10.4.6 (your
profile indicates that your a running 10.4.5).
Was updated to 10.4.6. I just forget to change the forums pref
I more thing to mention when I start the sleep mode manually everything is fine. I also tried to disconnect all external USB/Firewire hardware and tried it with a fresh mac os install on my USB HDD.
Nothing helped.
Thanks
