System not going to sleep as scheduled

Since OS 10.4.3 both my PowerMac G5 dual 2.0 Ghz and my 12" PowerBook G4 1.5 Ghz will not go to sleep as scheduled in the energy saver. I read all the posts about this and have not found a solution that works. Any ideas?

Well it took a couple of tries but after removing the following, suggested in another post, sleep function is back as it should be.
Remove the following then restart.
-/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-/Users/username/Library/Preferences/com.apple.systemuiserver.plist--(username is your name or System Administrators name).
You may not have this last one, but if you do, remove it like the others.
-/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist

System not going to sleep...

Hello All,
I have a Macbook 13.3, 2.16G's, 2G's or RAM running OS X ver. 10.5.5 all up to date, .. ... system issued to always go to sleep with no problem at around the time set up in energy saver prefs pane.
Now is not. configuration hasn't been changed.
Any one knows how I can find out what is interrupting or stopping the system from going to sleep?
Thanks

Thanks for the response. All that information made it simple to help.

External hard drives not going to sleep

External HDs (I have two) connected to my 2.26 unibody macbook are not going to sleep even though I have the appropriate check box selected in System Prefs. Running 10.6.8. Connected through the USB ports in my 23" cinema display. Any thoughts or suggestions?

Lion may not be able to put them to sleep (as it can internal drives). The drives often come with drive management software to do that (check that it is Mac OS compatible). I have two Segate drives that backup my server and then sleep, but that is managed by the managment software.

Just Updated to 10.5.2 on Feb 10, 2008, Display not going to sleep anymore

Greetings:
I am running on a Macintosh G4 Graphite (which has been heavily upgraded to a G4 1.8 Ghz processor (Sonnet Tech Encore) and it has 1 GB RAM and an upgraded ATI Radeon 9200 Mac Edition video card). Under 10.4 -10.5.1 everything worked fine.
I have my Power management settings set to put the display to sleep every 30 mintues and changed to 3 mins to check if something else was up.. but the display is definitely NOT going to sleep any more.
Any thoughts and is anyone else having this issue?
I have not yet trashed the preferences file, mainly because I am not sure where it lives.
Thanks,
Mike

Hello All Again:
Just wanted to update you on how I fixed the problem. Not sure what specifically in the combination fixed it, but it does now work
First I opened System Prefs > Energy Saver and hit the set to defaults button. I then exited System Prefs.
I then went into Terminal and ran pmset displaysleep 30 and exited terminal.
Lastly, I went into System Prefs > Energy Saver and selected 3 minutes. Exited System Prefs and waited and lo and behold it worked. So I rebooted my system and then set the timer back to 30 mins and it has been working again so far.
I suspect that the pmset from terminal may have refreshed something in the prefs file someplace, but again it was just something in that string of things I did that worked.

Computer hanging on closing lid and not going to sleep, indicator does not blink

i have a 1 month old Macbook Pro 13" i5 with 4Gb memory.
when i am closing the lid the computer is not going to sleep, hard drive continues to spin and power indicator does not blink and it remains solid.
on opening the lid again screen keep blank and does not show anything while i can hear spinning of hard drive. than i have to forcefully shut off the computer by pressing power key and than computer starts after that.
Apple support told me to press shift+control+option+power and than start computer, it fixed the problem only once and they told me to do it again when it comes again. but write now i am getting it everytime.

Hi guys -
First off make sure you don't have 'Wake for ethernet access...' enabled in System Preferences/Energy Saver/Options - I'd also run Disc Utility and repair your permissions as well. OS X requires 'maintenance routines' to be performed on a certain basis and you can use this free application to help you with that...Onyx.
Check the obvious as well - that you don't have any applications that might keep your Macbook awake ...some printer utilities do this for example.
After all this shut down and restart and hopefully things will be better - if not, there may be a chance that the mechanical parts that put your computer to sleep may be at fault ...and you'll need to visit an Apple dealer to verify this.
Hope some of this helps.

Computer not going to sleep when lid closed

My wife's new MacBook Air has a couple of problems we can't figure out. First sometimes the computer is not going to sleep when lid is closed and when we lift the lid everything is frozen.
Second, the user Library folder is not seeable in her user account. I know it's there because on the side bar there's a short cut to Preferences folder which we can open.
Strange behavior.
Thanks,
Ron

Ron,
The user library folder (~/Library/) is hidden by default in Lion. I assume Apple doesn't want people mucking around with the sensitive files in there. So this is normal behavior.
As for the freezing issue, I would suggest you reset your power management and perform a safe boot to clear out caches. You should also see if the issue persists after disconnecting USB perhipherals.
Here's how:
Power Management:
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
Safe Boot:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).

MBP not going to sleep

I have had my MacBook Pro for a little over a week now and i am noticing that it is not going to sleep according to my energy saver preferences, or at all for that matter. Any ideas?

Something must be preventing it going into the appropriate sleep mode; either some software running or a lack of space for the sleepimage file (most unlikely at this point). Run /Utilities/Console, click 'All Messages' top left and then select Sleep from the Apple menu top left - there should be some lines in the Console Log that will give a clue about what's going on (post them here if you like).

IPod not going to sleep correctly

Hi there,
I am having an issue with my iPod 5G not going to sleep correctly. When I select the "Sleep" function on the menu screen the iPod with stop responding to the wheel, as per normal, BUT the screen only fades and does not blank itself completely. I can still see the menu items.
Is this right? I though the screen blanks completely, to save on battery power.
Advice and thoughts needed...cheers
iPod 30Gb 5G Windows XP

Hi, I have managed to change the battery of my Ipod
mini, but still after the Ipod is fully charged the
battery life still lasts only a few hours....
My assumption after reading all the technical
documents, is that even though the Ipod mini appears
to go to sleep (either by itself or after the play /
pause) button is pressed for a few seconds, that in
fact the Ipod isn't a sleep and the battery runs
down....
I have updated to the latest 1.4.1. software... only
recently happened, and replaced the battery (but
perhaps it didn't need it).
And it's 14 months old so out of warranty...
Does anyone know of issues with sleep mode not
working correctly? Is there a software fix for
this????
Cheers
I think I'm having the same problem - let me know if you find an answer and likewise I'll do the same. Is going to sleep the same as turning off? Mine doesn't even turn off when I press down the play/pause button!

MacBook not going to sleep when connected to WiFi

Hi there,
my MacBook 3,1 is not going to sleep as long as it is connected to WiFi.
It starts the process of going to sleep as my VNC connection gets dropped but it stays awake. I can easily reconnect.
Everthing else is working fine. Any suggestions?

Hello everyone,
I'm facing the same syptom. I tried many things and now havw to live with putting the MacBook to slee by hand. I had some other issues just before that:
1: The MB returned randomly from sleep while being closed. That was annoying. I think it was fixed after installing smart sleep and doing some cleanup in the preference files.
2: Then I was put "randomly" to sleep. I figured that came from overheating the processor (thus I'm gld it went to sleep). The fan speed control was set to constantly 2000 rpm. Installing fanControl helped.
3: Lid closing did not init the sleep mode and the backlight is not turning off. Niether does it wake up on opening when I put it io sleep manually (I have to press a key).
The sensor for closing the lid seems to work, if it is the same which controls the maximum brightnes of the sleep indicator light (pulsing). It is darker when the lid is closed.
I wonder if there is some settings tool.
Besides I think the issues started after the Software updates around 12th of dec. 2008, with MacOS10.5.6 and the EFI & SMC firmware updates.
I'm eager to get answers.
Kid regards, Ralf.

PC is not going to sleep or shut down after upgrade to Windows10

Hello,I upgraded my laptop from win 8.1 to win 10.Now when I close the lid or press the power button, the computer turns the screen off, turns the WIFI off, no more hard disk activity but it is not going to sleep.Also when I shut it down it goes throught the same procedure but never turns off.To start again, I have to keep pressing the power button to turn it off, then turn it on again.I did the powercfg - energy and got this in the report, "USB Suspend:USB Device not Entering Selective Suspend"When the computer had just started, I don't get that message, it also goes to sleep and shuts down normally, while later, I get this message in the report and no longer sleeps or shuts down.Any suggestion ??Thanks

MBP 17" i5 not going to sleep - wakes up immediately

Hi there,
Every now and then when I try to put my MBP to sleep either by closing the lid, or by pressing the power button or through the menu, it will just turn on instantly after going to sleep. I have already tried resetting the NVRAM and SMC. I also made sure that no programs from the dock bar are still running.
This is what I read in the system.log:

I have read in other post that others are having problems with the i5 and i7 models trying to get them to sleep automatically according to their power management settings. I haven't tried this yet. Has anyone experienced a similar problem?

Looks like a USB device is waking it up. Very common.
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.
Next are 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

Monitor Not Going To Sleep on Mac Mini Server With Lion

Summary: I am attempting to configure a Mac Mini Server that runs OS X Lion. This machine was originally shipped with OS X Lion; it is not an upgrade. My current specific problem is that my Viewsonic VX2835wm monitor will not go to sleep when the minutes setting on the Display Sleep setting for Energy Saver has been reached. Instead, the screen goes blank for a couple of seconds and is replaced with a blank blue backlit monitor. (Ironcially, the display sleep menu cautions: "Never letting your display go to sleep may shorten its life".) I very much want and need the ability to have my monitor go to sleep so as to save energy and to extend the monitor's life for as long as possible.
Additional Background: I have had a couple of calls with Mac support and they have been unable to tell me whether this is a "design feature" or a flaw in the Lion OS because they have had no similar reports and they do not have the latest hardare available running Lion Server to test to see if this happens with other monitors. (They also, of course, don't have the VX2835wm monitor.)
I do, however, know the following:
(1) My HDMI monitor is connected to my Mac mini via a DVI KWM switch (ATEN CS1784) such that the HDMI output from my Mac is converted to DVI (using the DVI to HDMI converter that came with my Mac Mini) and is then run through the KVM and then converted back to HDMI (using a full pin DVI to HDMI cable). However, I have tested the monitor with a straight HDMI to HDMI cable running directly from the Mac Mini to the monitor and it has not changed anything.
(2) The Lion operating system correctly recognizes (in Hardware / Displays) the model of my ViewSonic monitor.
(3) I have a MacBook Pro running Leopard (OS X 10.5.8) that is connected to the same monitor through the same KVM switch (by way of a BookEndz docking station) which properly shuts down the monitor when there has been no activity for however many minutes are set in the Display Sleep setting under Energy Saver. (Indeed, all I want is the same functionality on my Mac Mini that I have enjoyed for the last two years with this MacBook Pro.)
(4) When fully connected to the KVM, if I switch from my Mac Mini to my MacBook Pro and my Mac Mini display goes to sleep while I am working on my MacBook Pro, when I switch back to the Mac Mini, my monitor backlight will be off (and the power light will be standby yellow rather than the blue on) until I wake my computer up by touching the mouse of keyboard. I wonder if this may mean that the Mac Mini's signalling of the change in status from on to standby is somehow dysfunctional.
(5) Shutting down the server functions (and other open applications) has no effect.
I would greatly appreciate feedback from anyone out there running a Mac Mini with Lion regarding whether or not their monitors go into standby mode when the Display Sleep time is reached (please note whether or not you are running the Server or Client version, whether or not it is a new install or upgrade, and what monitor you are using).
Thanks in advance to anyone who can help.

No, I didn't solve the problem. The monitor still goes to sleep with WIndows but not with my Mac Mini. About 8 months ago I basically wore out the power switch on my monitor so I bought a wireless power switch to shut it off at the outlet. The VX2835wm monitor itself is now starting to fail as well-- a couple of times it's gone through a weird sequence of flashing screen colors on power up and ended up in an overscan mode (that took me for ever to figure out how to fix). I have decided to replace my VX2835wm with a Dell u2412m once it fails for good partly because I really want to keep the 16:10 resolution (very hard to find these days) and partly because I want to see if a different make of monitor will go to sleep properly based upon my Mac Mini power down settings.

External displays not going to sleep?

Environment: Early 2013 MBP Retina 15'', OSX 10.8.5, two external HP LP2475w monitors connected via DP-DVI adaptors. The monitors are correctly recognized in the system report.
I am not running a screen saver, and in the Energy Saver preferences, I have set the display to go to sleep at 15minutes (long before the computer goes to sleep).
The built-in display indeed goes to sleep at the predetermined time, but the external monitors simply get a black screen, they don't actually go to sleep (indicator light is green, the backlight is still on). There is no problem with the monitors, they correctly go to sleep under both Windows and Linux.
My theories:
(a) vesa information about how to turn the monitors off is incorrect
(b) something about the mini displayport to dvi adaptor kills that signal
(c) there is no way to turn off external monitors, I'll have to live with this
Help?
Thanks!

exactly the same here. 2011+dell 24"
i called apple hotline and they did this with me:
http://support.apple.com/kb/HT3964
and
http://support.apple.com/kb/HT1379
after this the external monitor went to sleep flawless. ... but as soon as some usb-ports are busy (with an external drive or something) - even when everything falls asleep the external monitor keeps on again.
but a least without the usb the monitor now falls asleep too - so there is hope!
