Won't sleep without my lullaby...

I have a lovely iMac G5 with a 1.8 Ghz processor. It has become rather fussy lately and refuses to go to sleep unless I put it to sleep, by keyboard or from the menu. The screen will go dark, but the fan still runs, and runs, and runs. I called support yesterday, and reset the PRAM which seemed to fix the problem, but it's back today. Also, my screensaver would still kick in, even though I set it to "Never". At least that part is behaving now.
I am concerned for the welfare of my dear one here because she just endured surgery for a bad logic board in January. (We don't want to be separated again.)
Any other suggestions? Thanks.
PS-I have the OS X 10.3.9 ready to install, but I'm chicken. Will it create more problems or perhaps solve this one?

Hiya mommynow,
Try resetting the SMU: http://docs.info.apple.com/article.html?artnum=301733
Also, you should see if your machine is on the Apple Repair Program: http://www.apple.com/support/imac/repairextensionprogram/

Mac won't sleep after adding Kensington Wireless Mouse

I've added a Kensington PilotMouse Laser Wireless to my system and now it won't sleep, without first switching off the mouse. Kensington has no info on this, is there a workaround?
PowerMac G4 (Dual 867) Mac OS X (10.4.4)

The "sleep" that you describe is not sleep. Your mac has crashed but since it thinks it is sleeping there is nothing in the crash logs.
Sleep on modern computers is not just a hardware shutdown. Because X and XP are server based kernels they are designed to run 24/7 and do what they can to keep it that way. Deep sleep requires an orderly shut down of processes and loading their status into memory so that when it wakes, all is as it was.
There are many things that can prevent sleep. Usb devices are designed to wake a mac on a change of state (doing something). When my mac did what yours did the only fix for it was an erase and install. I tried all the other solutions but the only one that worked was an erase and install.
If you care to try some of the "fixes" then here are some.
Reset the pmu.

Computers won't sleep

Hi
Hope somebody can help me diagnose this problem.
I loaded some colour calibration software called Colormunki, by a company called Xrite. Since doing so both my G5 desktop and my Macbook will not go to sleep automatically.
There is no uninstall package with the software so I did a spotlight search for everything related to Xrite & Colormunki and removed everything, but it still does not go to sleep. I have run Applejack, just in case, but still no joy.
I have reloaded the software, and when I initially boot up and open a Console window, this is what is shown:
Mac OS X Version 10.4.11 (Build 8S2167)

The Colormunki software is in the account login startup, which I have removed, but it makes no difference in regular boot mode, still won't sleep.
Did you just uncheck it, or did you highlight it then click the little minus icon & reboot?
If you could advise how to show hidden files and where the file is located, i'll have a look to see if anything is in there.

FW800 won't sleep -- shuts down instead...

So there are many here who are having sleep/power control related problems, however I'm having a slightly different problem. As the subject line states, my FW800 Dual G4 won't sleep. Rather, when I select sleep it simply shuts down.
I have replaced the battery, reset the PRAM, reset the PMU, and reset the NVRAM, without success.
I suspect, however, maybe it's related to software as I can load up new system software and everything works fine. By the time I update everything to the latest software, including iLife, it no longer sleeps.
Short of taking the machine in, does anyone have any further ideas?

I have this;
If your Mac happily goes to sleep but won't wake up--Hold down the power switch to force-reboot your machine and get it running again.
Don't worry-your Mac isn't narcoleptic. Its Open Firmware system or NVRAM (nonvolatile RAM) is likely corrupt, and your Mac can't remember how to wake up.
Restart your Mac and immediately hold down the Command-Option-O-F key combo until you see a somewhat intimidating command-line display that ends with the Open Fimware prompt. Type the following line:
reset-nvram
press the return key on your keyboard
set-defaults
press return
reset-all
press return
Your Mac will reboot. Once it's running, put it back to sleep to test. If the problem recurs your Energy Saver preferences may be the culprit. Delete the com.apple.PowerManagement.plist file (go to Finder/Hard drive/Library/Preferences/SystemConfiguration)--don't worry, your Mac will regenerate a new one--and then restart to see if that rights the wrong.
Still didn't work? Might be time to call AppleCare or see an Apple Genius or a technician

MBP Won't sleep when the screen/lid closes...

I have had my MBP for almost a year now and my AppleCare is about to expire...
Recently when I close the screen the computer will continue to run and operate as if it was never closed and will not sleep. I took it to the Apple store and they did an SMC reset which sorta helped for about 5 hours. Now it goes to sleep but will take almost a minute at times or won't sleep at all. I was told I would have to send my computer out for a couple weeks but I can't do without a computer. Please help me fix this or help me convince Apple to give me a new computer.

Run /Utilities/Console and click 'All Messages' top left then close the lid and try and put it to sleep.
If no dice open the lid and look at the Console messages - in particular look for lines including "sleepimage" and see what it says ?
I suspect there's not enough space left on your hard drive, or it badly fragmented, and the RAM sleep image can't be created or stored properly ...

After 10.7.4 update macbook pro won't sleep

after 10.7.4 update, macbook pro won't sleep.

Test after each of the following steps that you haven’t already tried:
Step 1
 ▹ System Preferences ▹ Energy Saver ▹ Power Adapter ▹ Wake for network access: uncheck. You may need to unlock the preference pane by clicking the lock icon in the lower left corner and entering your administrator password.
Step 2
 ▹ System Preferences ▹ Energy Saver ▹ Schedule… ▹ Start up or wake: uncheck
Step 3
 ▹ System Preferences ▹ Print & Scan ▹ Open Print Queue...
Check all printers for unfinished jobs. Deal with any you find.
Step 4
Disconnect all wired peripherals except keyboard, mouse or trackball, and monitor, if applicable.
Step 5
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
Select All Processes from the menu in the toolbar, if not already selected. Enter “powerd” (without the quotes) in the "Filter" text field. Select the powerd process and click the Quit Process button in the toobar (stop-sign icon.) In the sheet that opens, click Force Quit. You’ll be prompted for your administrator password. The process will be relaunched immediately.
Step 6
Boot in safe mode and log in. The instructions provided by Apple are as follows:
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).
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.
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal. Don’t launch any applications at first. If sleep still doesn’t work properly, back up all data and reinstall the Mac 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, reboot 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 booting out of safe mode, post again.

MB: Won't sleep when lid closed and power connected.

Upgraded to Lion a few days ago and everything seems to be working great besides one thing:
When I close the lid on my Macbook (mid 2009) and the power is connected, the light remains on and the computer won't sleep. When i lift the lid everything is how I left it with no blink of the screen as it fires back up. However, when the power is disconnected, the computer sleeps fine when the lid is closed.
How can this be solved?
Thanks!!

OK, think I found my problem.
I had to send my laptop in for repair due to a faulty screen. When I got it back it all looked OK so the first thing I did was install Lion. Then I noticed the sleep issue so assumed it was Lion causing it. I tried the pram, SMC other settings but nothing helped. In the end I reinstalled Snow Leopard, same problem! I tried from bootcamp and same problem, wouldn't sleep when closing the lid.
Doing some googling I found a post where someone has the magnet in the display fail, which is what contacts a switch in the laptop when you close the screen. To test they suggest placing a paper clip on your screen bezel until it sticks to find the magnet, then finding where it locates when closing the screen on the laptop. Then run a small magnet (i used a small fridge one) over this location on the laptop with the screen up. I did this and instantly went to sleep!!! WOOHOO! remove magnet it wakes up, repeat and OK. Close screen without magnet and nothing.
So its gone back in for repair to have the screen replaced again.

Mini (Late 2009 - server) won't sleep!

All -
I have recently set up a Mini (Late 2009 - server version) as a small home server. Much of the time I'd like it to be asleep (in the middle of the night, during the day when no-one's at home). The problem is, it won't sleep. It doesn't seem to detect when it's idle and once it's awake - it stays that way. I can make it sleep via the Apple menu - but that's the only way.
My setup:
1 x Mac Mini SL Server (2 x 500GB Drives) connected via Ethernet cable (Airport and Bluetooth switched off) with 10.6.2; no mouse, no keyboard, no display
1 x Drobo connected to Mini via FW800
1 x Airport Extreme 802.11n (but only in bridge mode)
1 x broadband router providing DNS, DHCP etc.
Settings:
- Wake for Network Access set to On
My troubleshooting so far:
1. I've changed the default settings of "Computer Sleep" in the Energy Savings preference pane to 30 minutes rather than the default "Never"
2. I've tried resetting the SMC as detailed in http://support.apple.com/kb/HT1543 but it still behaves in the same way
3. When I manually sleep the Mini using the Sleep menu option in the Apple menu, the Mini sleeps and the wakes after about two hours with the following entries in /var/log/kernel.log:
Nov 13 12:12:51 server kernel[0]: System Sleep
Nov 13 14:00:51 server kernel[0]: Wake reason = RTC
Nov 13 14:00:51 server kernel[0]: RTC: maintenance alarm 2009/11/13 14:00:48, sleep 2009/11/13 12:12:52
Nov 13 14:00:51 server kernel[0]: System Wake
Nov 13 14:00:51 server kernel[0]: Previous Sleep Cause: 5
Nov 13 14:00:51 server kernel[0]: NVEthernet::setLinkStatus - Valid but not Active
Nov 13 14:00:51 server kernel[0]: Ethernet [nvenet]: Link up on en0, 1-Gigabit, Full-duplex, Symmetric flow-control, Debug [796d,0000,0de1,000d,cde1,3c00]
Nov 13 14:00:51 server kernel[0]: NVEthernet::setLinkStatus - link Valid and Active
Nov 13 14:00:51 server kernel[0]: R-state changed 2->0
My guess (and having surfed for answers) is that every two hours or so, the Mini wakes up and reminds everything on the LAN of the services that it's providing and then should go back to sleep. This would be fine if it did actually go to sleep ...
4. I've disconnected the Drobo so all that's plugged into the Mini is the power and Ethernet cable and it still shows the same problem ...
Anyone with any ideas or next steps?
Thanks, everyone - J.

Sleep has always been a problem. The current posts show this fact, this one “won’t sleep” and just above “won’t awake”
My energy setup for any systems or OS versions is always
computer sleep <<<<< Never
display sleep <<<< # of min
√ Put HD to sleep when possible
√ Wake for Network access
And I leave them running 24/7 unless away for 2+ days. I really doubt that my electric bill is any different. I also do not hear any sounds coming from other units not in use on the Network, so feel the settings are the same as sleep, without the problems.

IBook G4 won't sleep on schedule

I twice tried resetting the PMU as per Apple's instructions (power off then press and release shift, cntrl, option and power buttons) but it hasn't helped. My iBook simply won't sleep when it's scheduled to. The screen darkens when it's supposed to but no sleep.
This is the case both on battery and when plugged in. Both with external keyboard attached and without. Both set at 3 hrs and 1 minute. And it's been happening for several days.
It will only sleep when I close the lid or select sleep from the Apple menu.
Only recent software changes were the latest Apple system updates.
Ideas? Is there something else to reset?
Thanks.

Your method seems to have worked. My clock went back to 7:01 on 12-31-1969 (after I turned off the Airport, that is; the first time I tried this it automatically give me the correct date and time, so I wasn't sure I'd done it right). Then the iBook went to sleep on its own about 30-60 seconds after the screen went dark.
I should note, though, that I didn't wait that extra 30-60 seconds after resetting the PMU the first way. So that first method may have worked, too -- I just assumed it didn't when the iBook didn't go to sleep immediately after the screen dimmed.
Anyway, thanks for the great tip. Any idea why Apple doesn't mention this on its support page on resetting the PMU? Do you know anything else about this issue? Like why the PMU get's screwy to begin with?
Thanks again.

G4 Quicksilver - Won't Sleep

Ever since I connected a CRT monitor to the 2nd port on the graphics card, my G4 HD won't go to sleep. The monitor will play the screen saver for a bit then go to black as programmed, but the computer, fan and all, keeps running full-on. The monitor plugged into the AGP port at the time was a 15" Studio Display. Now both monitors are gone and I'm using the AGP port with a DVI adapter for a 20" Cinema Display and the problem is continuing.
On a seperate note, this may or may not be related, upon occassion the machine won't wake up unless I do a hard reboot. Could this all be problems with the PRAM? I just read on another thread to try resetting it, but if anyone has any other ideas, I'd love to hear them!
Thanks!

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.
In some cases, running MacOS X's cron tasks-maintenance that the OS performs automatically if you leave your Mac on 24 hours a day-can resolve many sleep problems. If you don't want to leave your Mac on, you can use MacJanitor, Yasu, or OnyX free at Versiontracker.com.
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.
Cheers!

Fan racing and won't sleep - please help

I have a 2.16 Ghz Intel 24" iMac. Recently I began to have the following problem. Once I use it for awhile and it starts to get hot, the fan activates on high. As a result, the computer will never go to sleep. Even if I try to put it to sleep manually, the display darkens but it immediately wakes up again and won't go to sleep without a shut down. I read all of the postings on this and can't find anything similar. I also should mention I have nothing but an Apple wired keyboard and mouse connected, along with an Ethernet connection to a TimeCapsule. In settings, "wake on Ethernet" is off and there are no apps in the start-up chain. I also verified and repaired permissions. If anyone has any ideas I'd greatly appreciate them. Thanks.

Redo the SMC reset, in addition to unplugging the power cord from the back of the computer (not the wall!!!!!!) unplug all peripherals such as external HD's, keyboards, mice, printers etc... When you re-start the computer only plug in the keyboard and mouse.
If that still does not solve the problem do a PRAM reset by:
_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.
Repost what occurs after you done both the SMC and PRAM resets.
Regards,
Roger

MBP won't sleep since Lion upgrade

Late 2008 MacBook pro, since upgrading to lion will not go to sleep. Screen goes dark, but fan continues to run, and power light stays solid without flashing. I've tries sleeping the computer with the keyboard shortcut, with the apple remote, and with the apple menu. Sleep mode works normally when the magsafe plug is disconnected, but not when it's connected. I've tried resetting PRAM and SMC, and quitting processes in the activity monitor.

I've been having a similar problem. I haven't found a permanent solution but I have found a work around. If you have TextExpander or Alfred this will work much faster.
I was able to use the 'pmset -g log' terminal command to find out that mDNSResponder was the reason my MBP wouldn't fall alseep. So it has something to do with Bonjour.
I then found a pair of command codes to shut off and turn on Bonjour. After using them, my MBP goes to sleep without issue.
Turn Off Bonjour: sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
Turn On Bonjour: sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
You'll notice that when you turn off Bonjour that you won't be able to use the Internet. That is the only down side to this work-around.
Using Textexpander you can use 'ssleep' and 'wwake' for the two command codes and alfred can give you quick access to the terminal.
I hope that helps somewhat.

MBP Won't Sleep automatically. Sleep light on. Not pulsing. Drive spinning.

I can get my new MBP SR to sleep when I tell it to but it won't sleep when it's supposed to according to my Energy Saver preferences.
Instead of sleeping, the screen goes dark and the sleep light stays on at medium - no pulsing. I can hear the hard drive still spinning. I tried changing my screen saver to one of the original Apple settings (Computer Name) but that didn't help. I'm going to try throwing away my Energy Saver prefs.
Any suggestions?
BTW - I took a closer look and I was a bit surprised at how many posts there are for the MacBook Pro on the Apple.com discussions. The most posts per day of any model by far. I know its a very popular Mac but this model seems to have more problems than we are able to solve. That worries me. Anybody else noticing this?
-Todd

I had exactly the same issue and needed three hours to find out the reason. It was the Bluetooth Mighty Mouse. I had to disselect the *third option* in the *bluetooth preferences*. I have a German-language OS X so I don't know the exactly expression but it affects the ability for bluetooth devices to weak up the system.
If you have EyeTV 2: This application must not be running. If you have scheduled recordings that doesn't matter it will record anyway: It will wake up the Mac - record the thing - go to sleep again.
I have several devices connected to the MBP: Three external enclosures with harddisk drives (2xFW800, 1xUSB without sleep function), EyeTV 610, speakers - all those things did not prevent the system for going to sleep. All those devices can be left attached - up and running. The FW harddisks will go to sleep the USB not.

My MacBook won't sleep and I'm forced to reboot...

For the past two weeks, every other time I close my MacBook it will either sleep or it will not sleep. When it won't sleep, the light on the apple turns off but the little indicator light stays on and I can hear the fans whirring. When it stays on instead of sleeping, the screen is frozen and black and I'm forced to turn the power off then turn it back on. I've tried a few things including taking the battery out and holding down the power button but nothing seems to be working. My nearest Apple approved service provider is about an hour away and I don't mind taking it but if I can fix it without making the drive that would be awesome. If there are some specific things you need to find out my computer let me know and I'll fill you in. Any help would be very much appreciated.

Failure to sleep can be caused by hardware or software. To troubleshoot the problem you'll want to make sure nothing is connected to the computer but the power adapter since a USB or FireWire device might be the cause. Your computer came with a hardware diagnostic disc - either it is part of your installation DVD or it is a separate disc. Boot up with that disc and let it run. If it shows a problem you know you need to make a trip to the shop. If not, we can't positively eliminate hardware but we'll move on.
You'll need to create a new user account, after which you should shut down the computer and then restart and log in directly to the new account. This will eliminate any start-up items that might be causing the problem as well as any munged preferences that might be the cause.
If the computer continues to show shutdown issues you'll want to look at: 1) 3rd party drivers such as all-in-one printers and scanners - uninstall, restart and try again, 2) RAM upgrades - remove and try again, 3) an OS reinstall (which I've saved for next to last), 4) computer hardware. If you get to the OS reinstall, I'd recommend that you fully back up the computer and then erase the hard drive, reinstall the OS, and immediately try sleeping the computer.
Shutdown and wakeup issues are the two problems I hate dealing with most.

Macbook Pro won't sleep after updating to 10.4.11

Hi,
I just updated to 10.4.11 reluctantly from 10.4.9 as whenever I do update I always have issues...I basically just went to software update last week and updated to everything I could. I've just been reading the forums and noted that updating is not always that easy...
Well basically my computer won't sleep if the lid is left open, this is IMMENSELY annoying since I often leave my desk to work on drawings, and I don't want energy being wasted like it is at the minute. Call me picky but I just want my computer to work.
I've reseted the PRAM, (option, alt, p and r), closed all applications, etc, but no luck...
Its a 2.2ghz MacBook pro, 2GB. Thank you in advance
Neal

The important thing for the future imho, is to always Repair Permissions before & after any update... seems to ward off most of these problems. Of course that is only good if the disk is Verified once in awhile.
Using Disk Utility in Mac OS X 10.4.3 or later to verify or repair disks...
http://docs.info.apple.com/article.html?artnum=302672
About Disk Utility's Repair Disk Permissions feature...
http://docs.info.apple.com/article.html?artnum=25751
In fact I'd start with those 2 now, if that doesn't help you may need to reapply some updates by getting them directly from apple>downloads.

Won't sleep without my lullaby...
