Won't sleep, won't wake

I'm having two problems with sleep mode:
WON'T SLEEP
my iMac G5 won't sleep even though sleep mode is activated in Energy Save preference pane (file sharing off).
WON'T WAKE
When I put my machine to sleep at night (sleep item under apple menu), it won't wake up in the morning. The blinking sleep light indicates my iMac is in sleep mode. I hit a key to wake it. The sleep light turns off. Nothing else: no noise, no screen but the black on. I wait a few minutes and press the power button: nothing happens. Once it starts up after a hard boot (power button, 5 secons). Most of the time I have to wait an hour or two and then I can start up my machine by pushing the power button.
This problem occured yesterday for the first time. Today I did many test with same results: no wake after "manual" sleep mode and no "automatic" sleep.
Note: Apple Hardware Test did not detected any problem.

Even though the hardware test did not indicate a problem, you may still have one. I'd give AppleCare a call. Also note, if you are out of the one year or AppleCare coverage, you may still qualify for this program:

Mac Mini either won't sleep or continually wakes up from sleep

Well, I think I've tried everything...
My mini won't sleep on it's own through energy saver. I can force it to sleep by choosing it in the apple menu - and it will stay asleep. And it will go to sleep through the schedule. I installed "Please Sleep" which forces the mini to sleep but it wakes up 10 seconds later. The monitor sleep works fine.
I unplugged all USB devices - still didn't work.
So it must be a rogue process or something? Is there a way to know which one is forcing the Mac to stay awake? Or any other suggestions?

If you haven't already, try resetting the SMC per this link: Intel-based iMac, Intel-based Mac mini: How to reset the System Management Controller

Computer won't sleep, my monitor wakes up my computer

I recently purchaced at T232HL for my PC. It was working fine, now whenver my PC blanks the display or goes to sleep the monitor starts looking for another input then wakes the PC back up. The computer is plugged into HDMI1, when it goes to sleep the monitor tries HDMI2, VGA, then back to HDMI 1, then displays "No Signal", the amber light comes on briefly (0.5s) then the screen comes back on to my lockscreen with the PC wide awake. Using powercfg -lastwake I can see that a USB device woke up the computer. I tired unplugging each device 1 by 1 and found that when the USB to the monitor is unplugged it goes to sleep without issue (it still cycles inputs, but doesn't get woken up in the end). What's going on here? I don't think the monitor was cycling through input when I first started using it, and it certainly wasn't staying awake. Any hints on how to prevent auto input searching and preventing the monitor from waking up my PC? Thanks-Ian

RidgePirate,
Go to the device manager.
Right click and go to the properties of your display adapter.
Go the power management tab and see if there is an option to wake the computer from sleep.

Applications freezing, won't sleep, won't shutdown

I've only had minor problems with Leopard, but have become quite concerned of late.
Over the past few weeks, Skype (older version 2.x??) would suddenly freeze with the beach ball, and nothing would make it shut down. I would try force quit without success. Went into activity monitor, but it wasn't even being shown there. It was, however, still showing as being open on the dock.
I have to use skype everyday at work, so sometimes I would continue plugging away on the internet, then Safari would start to freeze and I'd have the same problems with quitting Safari. I'd manually force a reboot by holding down the power button, and usually i'd be sorted out.
I'd be fine and then a few weeks later this mysterious behaviour would reappear. I downloaded 10.5.8, then Safari 5.0.6, and decided to get the new version of skype 5.2
Things seemed fine until today when these same symptoms reappeared. This time, however, they seem worse.
1. skype would sometimes merely bob up and down when i tried to open it. when it did open, it would freeze upon receiving a message
2. safari would then (sometimes) follow suit. freezing up. sometimes it didn't (i rebooted using power button numerous times today)
3. i tried to open itunes and it would bob up and down without opening. on another occasion it did open, but when i tried to play a song it froze.
4. when things *seemed* to be running smoothly, the fan would be whirring away...even though I only had MS Word open.
5. Again force quit would do nothing. Skype would never show up in activity monitor, despite showing on dock as still being open. itunes, however would show up in activity monitor and i coudl quit.
6. other applications (i checked for new software, for example) would randomly freeze adn general operations were sluggish.
7. After a cold reboot, I tried to logout again without having opened any applications and it would merely hang and not logout/restart/shutdown. I went into activity monitor again to kill login to see if that woudl work, but again it would just hang.
8. when it appeared to be running normally (minus the whirring fan), i closed the lid to put the computer to sleep, but it did not sleep.
Those are the symptoms. I've tried:
-repairing permissions
-trashing skype
-clearing cache (system/kernel)
using onyx for various other cleanups
but the problem persisted.
Verifying disk said all was ok. unfortunately, I do NOT have my original disks with me. I am currently overseas (to where I would normally call home and foolishly did not bring).
I hadn't tinkered with anything nor downloaded anything odd.
running 10.5.8 on MacBook. 2.2GHz 2GB memory have over 10% of free disk space available.
if anyone has any ideas, would appreciate it.
A big clue, perhaps....I decided to log into my Admin account, and safari is acting fine, adn the fan is not going crazy. not sure about skype, as i keep this account pretty bare, but shall try downloading later and report back. Will also post a log of when itunes froze
Thank you !

i've returned home now and everything seems to be fine again. strange!
I read a different thread in which someone described a problem of applications not shutting down, and thinking it had to do with his wireless connection.
that sounds too bizzarre to be true, but that's the only thing that's changed from when i was at work until now at home.

Won't sleep, won't start up.

I've had two problems today. My iMac was shut down last night and this morning it would not start up for me at all. After 3 attempts at starting from the power button with no luck I eventually had to unplug it from the wall. That worked but once the start-up was complete I had the message that "Mac OSX had unexpectedly quit". I was hoping this was the end of the problem.
I did the software update today and then repair permissions.
That's when my computer decided it would not go into sleep mode at all. I eventually did a restart to see if that would fix the problem. The same message appeared "Mac OS X had unexpectedly quit".
Does anyone know what's going on here ? This iMac is only 6 weeks old.
14 iBook G4 768MB; 20G iPod Mac OS X (10.3.9)
20" Intel iMac, 20G iPod , iPod shuffle Mac OS X (10.4.9)

The two things I would try are;
1. Reset the NVRAM, and.
2. reset the SMC.

Won't sleep, wakes spontaneously

My new Mac Pro has some odd behaviors. First, when using the keyboard shortcut to make it sleep it sometimes won't respond the first time. Sometimes it sleeps right away. Sometimes it takes a few seconds. Sometimes it won't sleep at all unless I use the menu item.
Another oddity is that it sometimes wakes spontaneously for a few seconds then goes back to sleep by itself.
Are these known issues? Are there fixes known?
Thanks.

Look at your kernel log with the Console.app (in your /Applications/Utilities folder). It might give you a clue who might be waking you machine back up. Look for a line that contains the words "Wake reason". There will be some letters to the right of the equals sign following the wake reason indicating the device that caused the wake.
Here's a list of some of the reason codes, and for that matter it's part of an article about sleep failures.

IMac 2011 screen unexpectedly goes black (to sleep), won't wake

I've been having an intermittent problem. I'm using an iMac (late 2011) with 10.7.3. I'm doing things on the computer or some process is going on when the screen instantly goes black (no dimming first). If a video was playing, I can still hear it playing, but pushing keys on the keyboard or mouse or pad does nothing to wake the screen. Sometimes pushing the power button a number of times will get the screen to come on, sometimes it won't. When the screen goes black, if an external drive was running and then stops, I can sometimes get the screen to come to live. Sometimes this black screen happens when I'm burning a DVD; when the DVD is finished, I can bring the screen to life. I thought one of my two external drives was bad, so I disconnected it. That seemed to help (though verifying the disk revealed no problems). But a few minutes ago, the screen instantly went black again; no dimming first. There have been times I thought this was associated with a new bit of software, but then it returns even after I delete the suspect software. Sometimes I have to use the power button to shut down the iMac then restart it. Once, I had to unplug and replug the iMac before I could get the computer to respond and the screen to return to life. I don't know if this is a hardware problem (internal or external), a software problem, or some combination...or something I haven't thought of, at all. Very annoying. Verified the internal drive, repaired permissions; no problems noted there.

Exactly the same issue here - same machine and OS. got so bad now that it blacks almost as soon as it comes on. Over the past few weeks I also experienced the flickering screen that others have complained about. The black screen only occured after installing latest update (7.3) - and I only installed this after earlier problems with the update reported by many users were sorted - but the flickering happened before so may be not relevant.
What's happening when you press the power button a couple of times is probably that you have 'use power button to put computer to sleep' selected in System Prefs. Henmce, 1 push puts it to sleep and 2nd wakes it up.
I have done all the usual checks plus power down, unplugged for 20 seconds and then restarted to reset the SMC (System Managemenmt Controller) but problem has recurred - normally after sleep.
Aplle did have a large batch of faulty LG screens apparently so maybe this is the poblem. Otherwise maybe graphics card issue,

Won't sleep, wakes right up

Everytime I put my MacPro to sleep it wakes up 4 seconds later and TURNS ON MY SCANNER? I've reinstalled the scanner to no avail. Also after falling asleep due to inactivity, it wakes up and goes to sleep off and on during the night. Any suggestions?
MacPro G5 Mac OS X (10.4.8)

This is for a Mac that won't sleep.
First, read things in Apple doc.#25801 on sleep settings.
Here is Apple doc.#303698 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 recieve 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 Recieve Faxes On This Computer box.
If that does'nt 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 cards.
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.
Cheers!

MacBook Pro won't stay asleep with external monitor attached. When sleep is selected from the Apple menu the computer will go to sleep only to continually wake up...go back to sleep...wake up...etc. every few seconds.

MacBook Pro won't stay asleep with external monitor attached. When sleep is selected from the Apple menu the computer will go to sleep only to continually wake up...go back to sleep...wake up...etc. every few seconds. This only happens when using the external monitor. Does anyone have any suggestions?

Mine does that too. The worst thing is when it goes to sleep, then wakes up and keeps running while the lid is closed and it is wrapped up in a case. I am afraid when the hot weather comes it is going to burn up. I am hoping Apple fixes it in the software or they may have a melted MBP to replace.
Then when I open the lid it is crashed running at fill tilt, pumping out heat to beat the band. I am forced to hold the button down and reboot.
I wiped my hard disk and reinstalled my OS, but it didn't help. I reversed my OS to 10.5.0 and it solved the DVI problem but still won't sleep. This post will probably be deleted by Apple, they did it a few days ago. I just don't know what to do, and I consider myself a real Apple expert. Just hoping you realize you are not the only one.

Sleep - won't wake up, and now randomly goes off to sleep

Since the recent security update, my 1.67 G4 Powerbook has been experiencing problems with sleep. Sometimes it won't wake from sleep, forcing me to hard reboot or pull all power out, and now it's randomly falling into sleep when it shouldn't.
The issue is progressive - it will sleep, then I wake it, then it goes down again 2-3 minutes later, wake, then seconds, wake, then deep somnambulistic slumber.
I read in Macintouch that there was a fix recently for Intel MacBooks and sleep, but some of us in the PPC world are feeling it's effect.
I've reset the pram several times, and on one occasion the fan spun up very loudly on boot, then quieted down after 5 seconds. Might be nothing.
Another factor is the battery - pull the battery and the system behaves better. I wonder if there's a lowered thermal limit that, when the battery is charging, causes the system to shut to sleep...?
Anyone else having this problem? I'm ready to slip back to 10.4.9 to see if that makes it more stable -- this happens several time a day now.

For other who may be watching this...
The laptop did keep shutting down into sleep, but - following from a tip from another site - I began trying three things: One or all seem to have resolved the issue:
* Repair permissions - often and always. Something does get munged and I'd be interested to see if anyone else has the same files affected:
Permissions differ on ./Library/Widgets, should be drwxr-xr-x , they are drwxrwxr-x
Owner and group corrected on ./Library/Widgets

* I stopped zapping the PRAM when it went to sleep or wouldn't stay awake on boot - I just booted from DVD instead and, lo and behold, the thermal errors didn't occur under the DVD. Fixed permissions and a reboot it often worked fine for hours.
* Running it alternatively from either battery or from mains. Initially under the battery, it would sleep at 70-60%, then - after a few days of being shut down instead of slept - it began running down to 0. I'd have to plug the unit in and charge it whilst off, but now -- after a week of this - everythings back to normal.
Ultimately, I'm sure this software. Something is up - and slowly, if you're patient, you can bring your system back without buying a new case or motherboard.

Won't sleep, yet won't wake.

I have a problem with my MacBook that I think others have had too, but I can't find a post about it. Probably 1 out of 2 times that I close my MacBook to put it to sleep, it won't go to sleep. And no, I'm not waiting for 2 seconds and deciding that it won't sleep...I wait for around 30 seconds. If I open it up, however, it won't wake up, and the computer is completely frozen and I have to force-shutdown.
I am running Leopard, however this happened with Tiger as well, so I don't think its a Leopard-related bug.
Also, it seemed to go away (when I had Tiger) after I deleted the hidden volume that it uses to store content for safe sleep, but I would like to be able to keep safe sleep enabled.
Any ideas?
Thanks,
Zeb

You just described my exact same problem to a tee. But, I want to include an additional nightmare. Not only did I have these problems, it actually would sleep when I opened the lid. Then I'd close again and it would wake.
Then, I upgraded to Leopard last Friday. I crossed my fingers but to no avail - no change.
Then Saturday morning I noticed that the screen saver wouldn't come on. I tried a shut down and that didn't work either. I held the power button for 5 seconds and left Starbucks thinking that it might not come back on.
When I got home, I started my Macbook (it worked thank goodness) and immediately tried a re-set of SMC, PRAM, and Permissions for the umpteenth time since about August.
Guess what? To my surprise, everything started working like I had a brand new MacBook. It sleeps and wakes like it's supposed to, screensaver is good, and it will shutdown when commanded.
Please give it a try and see if you have the same result.
I'll root for you. Good luck.

Macbook Pro late 2008 17inch won't sleep or wake up

Recently I inset a SSD as a primary disk for the system and the original hard drive for storage. The system was upgraded to Marvericks 10.9.2. The computer is Macbook Pro 17 inches Late 2008 edition, A1229.
When I close the lid, the computer won't sleep. I tried to close lid under safe mode. It works fine. However, even if all the programs are closed, the computer won't sleep when the lid is closed. I tried to change the settings for power saver and bluetooth. It doesn't help.
There are so many people experiencing the same problem. I can't believe there is still no solution. PLEASE HELP.

My mac pro won't sleep on its own or when I try to put it to sleep.

Hello all,
I have a 2007 Mac Pro and for some reason, it won't go to sleep. Normally if it was idle for an hour or two, it would automatically sleep but not anymore. If I put it to sleep manually, it wakes right back up. I have to shut it down so the hard drives don't spin all night long. I'm not sure what's causing this. I tried unplugging all the USB devices and plugging them back in. It tried resetting PRAM. In my preferences, my computer sleep prefernces remain unchanged from the time that it was functioning correctly. If anyone has a suggestion I would love to hear it.
The text below is from terminal after typing 'pmset -g assertions' Perhaps it will be helpful in diagnosing the issue.

Test after each of the following steps that you haven’t already tried:
Step 1
Take all the steps suggested in this support article.
Step 2
From the menu bar, select
 ▹ System Preferences ▹ Print & Scan ▹ Open Print Queue
Check all printers for unfinished jobs. Deal with any you find.
Step 3
 ▹ System Preferences ▹ Sharing: uncheck all boxes.
Step 4
Reboot and see whether there's any change.
Step 5
Reset the SMC.
Step 6
Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post 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 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 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.

Machine won't sleep on it's own.

This may not be a Leopard specific issue, I had it with Tiger also. My eMac and new iMac won't sleep with the HP All-in-One printer software installed. The software has three active apps (one which controls a root process) that won't let it sleep. I can manually sleep it, but the energy saver setting is useless. The display will sleep, but not the machine.
I posted in the eMac category, but this is not machine specific, either, seems to be HP specific.
I trashed the culprit apps, but then I couldn't scan (the device was not found); it did let the machine sleep, though. I tried fixing the permissions after re-installing the latest software from the HP site (a VERY long process), and turning off the printer, still no sleep.
Anyone else have this issue? Any suggestions? I thought maybe if I created an alias for the culprit apps and stored the originals on a removable device, or even a .dmg and only mount it when I need certain printer functions, that may stop them from constantly running.
Any help would be appreciated

Thanks gws,
My eMac FINALLY achieved sleep last night after about 50 min. I have the sleep timer set for 1 minute, maybe the fact there was a scheduled TM backup kept it awake. I have the printer turned off, and it has been manually slept and re-started since it was turned off, don't know if any of those was a factor.

I had anacron installed, but removed it the best I could, it is not needed in Leopard.........
Thanks for the advice, gws, maybe your system would react the same after re-start and/or sleep with printer turned off?

P.S. Be sure your Mail is not set to check for new mail every 1 minute, that will stop sleep, too

MacBook Pro won't sleep with external monitor

Hello,
have a problem. I'm using external monitor with my MacBook Pro. If I close the lid, I see all windows on external monitor and Yosemite won't sleep. Can you help me please? My external monitor is Samsung 21.5" and I'm connecting it to MacBook Pro via DVI.
Thank you

Hey Renecek,
My first thought was, "Hey, you are using closed-clamshell mode".
How to use your Mac notebook computer in closed-clamshell (display closed) mode with an external display - Apple Support
But then I realized, wait, you want it to sleep.
For that, check out the suggestions in these articles.
OS X Yosemite: If your Mac won’t go to or stay in sleep

Take care,

Won't sleep, won't wake
