IMac won't go to sleep on its own

I set my iMac to go to sleep after 15 minutes of inactivity. Everything worked as it should until I updated Lion to 10.7.3. Now it seems that iMac never goes to sleep on its own. No new hardware installed whatsoever, every settings are the same as before. I even tried by not running any programs, and it still won't go to sleep unless I force it to. It's a mid-2011 iMac with core i5.
Any ideas?

I don't have an explaination for a cause. But in the end, if you don't figure out the cause, try using PleaseSleep which attempts to force the system to obey the energy saver preferences.
FWIW one explaination is that there is some process keeping the machine awake. Look in the Activity Monitor for possible suspects.

IMac does not go to sleep on its own- HELP!

I have an iMac G4 17", it's about three years old, and I absolutely love it, except now it does not go to sleep on its own. It will go to sleep when you select Sleep from the Apple menu, but not when it has been inactive. In system preferences under the energy saver menu it is set to sleep after being inactive for five minutes (screen sleeps after three), and the screen does power down, but the computer itself never goes to sleep on its own (you can still hear the processor making noise (fans?) and the little white sleepy light doesnt come on) I can't seem to figure out what could be making it stay awake (no applications are running), I'm not sure if it has something to do with my external DSL modem (though i think i had the problem before i got the dsl), I tried turning off the "wake for ethernet network administrator access" and it didnt change anything. Any help?

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!

My iMac will no longer go to sleep on its own!

Help!
My iMac will no longer go to sleep on its own! No matter what my settings are under 'Energy Saver', the computer will NOT go to sleep. Rather, the monitor will just turn off and the white light on the front of the computer will come on. The white light does not 'throb', so I know it isn't sleeping.
I'm not running any weird applications preventing it from sleeping, I've tried booting in safe mode, and I've tried resetting the SMC.
This is a RECENT problem - I think it started occurring after installing the 1.0.1 firmware OR Mac OS 10.4.6 update. Does anyone else have this problem??
AHH! Thanks for your help!
Jonathan

Hey everyone -
Thanks for your suggestions.
David.Austin - yes, my power LED does not fluctuate, so I know the computer isn't sleeping, the display is just 'off'. I do have all my disks set to go to sleep. This is a recent problem - everything used to work just fine.
joejoe - I haven't yet tried zapping the PRAM (or NVRAM), but I give that a shot and reset the SMC (SMU) again. If that doesn't work I'm going to have to do a... re-install.
I'll report back with my results. Glad to hear I'm not the only one with this problem.
Agreed - there is something wrong with one of those two updates.

IMac wakes from sleep on its own with Yosemite

After installing Yosemite, my iMac wakes from sleep all on its own multiple times throughout the day and night. The screen does not turn on when this occurs and it goes back to sleep on its own. I figured the my energy settings may have changed after the upgrade, but nothing is different. I have no schedule set and the "wake for network access" is unchecked.

To my knowledge, any Mac that is 1. connected to power and 2. not powered down will wake periodically for the reasons I explained, and perhaps for additional reasons known only to Apple. If disabling "wake for network access" does not change anything, all I can say is that it's working as Apple intends it to work. Before you ask, I strongly discourage you from finding clever system "hacks" or workarounds to prevent your Mac from working as designed.
It may or may not be a bug. Whether it is or not though, if it bothers you, consider providing feedback to Apple.
When questions such as yours arise, it helps to look at iOS. iPads and iPhones will all periodically connect themselves for the purposes of downloading emails, Messages, alerts etc. There is no way to disable that, other than to completely power down the device, which almost no one does. Apple has been inexorably changing OS X to effectively implement iOS design features such as this – for better or worse is not for us to say.
May I ask why this concerns you? Perhaps that would lend some insight regarding possible solutions.

My iMac won't go to sleep

I have gotten one of the new black and silver Intel iMacs, but a small issue popped up yesterday. The computer wouldn't go to sleep on its own. The screen would go black as if it was preparing to sleep, but the fans/disks were still running. If I click the sleep button on the login screen, it goes to sleep just fine and then wakes up normally.
I went onto the forums and looked around. I don't think it's because of anything external hardware because I have a wireless Airport base station, so the only things plugged in are the keyboard, mouse and power cord. I kept looking and found something that said to go into the preferences and go to Energy Saver/Options and uncheck the box that says "Wake for Ethernet network admin. access". Now it seems like I've found my answer, but I just want to be sure. Will unchecking that box fix the problem? Or maybe this is something that will go away on its own.
I just want to have an expert confirm this before I go messing around with my system.

OK finally weighing back in here.
I was going to reset the SMC, but instead I just did a pretty major software update, one of which was to 10.4.11. Repaired permissions first.
I used to have my 24" iMac set to sleep at 15 minutes. To test the function after the updates, I set the panel to 3 minutes, turned off all externals. Voila! It slept in 3 minutes. Not just the screen, the whole iMac.
Here's the log file that shows what I updated. Certainly could be lots of culprits in there. I seem to always hold of on updates, since they so often seem to have bugs of their own, but all of these are mature, maybe even revised, so I took the plunge. I hope this helps anyone with the same problem.

My Macbook Pro started freezing all the time & going to sleep on its own for no reason

I've been having trouble for a few weeks with my computer freezing way too often for seemingly no reason - I'm using it exactly the same way I always have with no problems, and even actively trying to have less applications open (which seems to have no effect). I can't always load simple webpages without it freezing and giving me the color wheel and it's just MUCH slower in general. It is seriously making it difficult to use my computer for work or for fun...
It has also started going to sleep on its own - the screen will just go black (or sometimes BLUE) and the keyboard lights turn off, and the only way to get it to wake back up is to close the computer, wait, open it again and click or press a key. It doesn't respond to any keys/clicks until it has been closed and reopened.
It seems to overheat really easily lately as well - but it does not always overheat when it freezes.
SMC reset did not seem to have an effect. Activity Monitor doesn't show anything crazy, everything is pretty much 0% except Firefox around 7-12% as I'm typing this. 246 GB available on my hard drive so that doesn't seem to be the problem either. Right after restarting my computer it seems better but the problems quickly resurface...
I googled for help before posting this and someone had suggested running the command
syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|find tok|n Cause: -' | tail | open -ef
in Terminal, which they said "Normally the command will produce no output, and the window will be empty." But mine gave this:

Eric - I dont understand how I'd use caffeinate. I am not running any code or particular script. My system goes to sleep if surfing the web, or running Word or Excel, etc.
Or.. Are you saying I should go through and type 'caffeinate X' for all of my applications?

My iMac freezes and sometimes shuts down on its own. Any suggestion on how to fix this? Thanks.

Macbook wont go to sleep on its own

hi guys...my macbook wont go to sleep on its own. i mean, Energy Saver Preferences is set to turn-off the display in 1 minute, and to make the computer sleep in 3 minutes - but the macbook wont turn off the display or sleep, based on the settings. Bt the way, when i make it sleep (Apple menu or by using Command-Option-Eject), the computer sleeps - no prob when sleep is manually executed.
Help please!
Thanks

In my case I think (not 100% sure other than a usb cause) was/is (b); a non-apple usb wired keyboard with its own usb ports or a bluetooth dongle plugged into my 27"s usb port. I am not about to part with either of them. And it just wasn't worth my time narrowing it down any further if that was at all possible so (c).
hi, i take your points, given you start your reply with "yes".
i'm in a similar boat and i've spent far too long scouring the apple discussions for a solution (with some issues you're better off googling than coming here for truth). i have also got a case open with my applecare coverage but the responses so far have verged on ignorant (i think they respond badly so you go away), so on we go.
i'm astounded that the terminal command pmset -g doesn't always provide an answer, but it seems a decent part of the solution. checking over the console and activity help too.
i've never had the issue with other hardware, so it must be a combo regarding the newer stuff + lion, wouldn't you say?

HP Photosmart 7525 e wakes up from sleep on its own hourly.

My Hp Photosmart 7525 wakes up from sleep mode approx. every hour. It is set up as wireless and usb. is there some setting or update that I need to apply to fix this problem?

Hi DanHannon, Welcome to the HP Forums! I understand that your printer is waking up from sleep on its own hourly. I would try the following: 1.) Update the firmware. Getting the Latest Firmware and Product Updates. 2.) Plug the printer's power cable directly into the wall outlet, not a surge protector. Hope this information helps, and have a great day.

Macbook will not go to sleep on its own since Lion.

I have a macbook running Lion 10.7.5. I also use an external monitor. The macbook will not go to sleep on its own and I think it has something to do with the monitor. Any suggestions?

You can test as to whether this issue has to do with the external monitor. Disconnect the display. If the MacBook now goes to sleep normally, then the issue is with the display. If it does not then the issue is with the MacBook.
Best of luck.

Help needed - refuses to sleep on its own

My 733mhz powerpc g4 refuses to sleep on its own even though the energy saver settings are correct. OS10.3.9. No bluetooth devices attached, standard keyboard, mouse and monitor. ADSK cable attached, and a printer, that's all. Who can help? Many thanks,
Uli

The workaround is to disconnect the cable before you want the Mac to sleep, and reconnect it when you want the computer awake.
Some USB devices, and your printer is apparently one of them, have the annoying habit of asking the computer, "Daddy, are you still awake?" every minute or two, sort of like my children when they were two years old and I was supposedly reading them a bedtime story. Short of swatting it with a two-by-four or disconnecting it, there's nothing you can do to stop it.

IMac won't wake after sleep

Hi
I have a brand new iMac 21.5" with Hybrid drive.
Its OS and apps are fully update to date.
Strange thing is that it won't wake from sleep.
To reboot, I have to turn the power off at the wall and back on again. Neither of the usual
wake/reboot processes work (holding the power button briefly or holding the power button for
> 10 seconds). No combination of opt/ctrl/cmd/power work either. I have to turn it off at the wall
and back on again, after which it immediately boots.
I've reset the SMC and NVRAM/PRAM.
I've checked the power options - which are set to defaults (sleep after 15 IIRC).
I've also checked the console log at the time of sleep - and there is no indication of anything
going wrong (an example is below).
Does anyone have any other ideas as to what I can try before going through the painful process
of sending it into the shop?
Many thanks.
Paul.
Console log below. You can see the machine went to sleep after 12:05pm, and I woke it up and 8:20pm. There seem to be no unusual messages in the middle.

I have gone to the apple support team - and they took me to the standard apple "what happens if your mac won't turn on" page
(If your Mac won't turn on - Apple Support) and walked me through the standard checks (which I'd already done).
The support guy thought it was a bad driver - I'm not so sure as I haven't installed anything new (just updates).
Anyway - I was just hoping/wondering someone in the wider community had seen this issue before I take the machine
in for servicing.

IMac won't go to sleep

I have an iMac PPC G5 running OS 10.4.11.
No matter what I do I can't get it to go to sleep when it is inactive. I've set the Energy saving preference to put both the display and hard drive to sleep after several minutes of inactivity. I turned of the wake modem activity option and the wake ethernet option but the iMac still won't go to sleep when it is inactive.
I'm connected to the net by DSL.
How can I fix this problem?
Thanks Panther

BDAqua and AcEvergreen... thanks for your posts.
I forgot to mention in my first post that the problem is really with the hard drive. The display will go to sleep but the hard drive will not.
So I unplugged everything in the back except the keyboard and the DSL ethernet. Then I set the Energy Saver preference to sleep after one minute (with the HD sleep option checked) and I waited. The display went dark but the HD did not spin down.
Then I unplugged the DSL line, restarted and tried again with only the keyboard connected. No printers, ipods, USBs, firewires or ethernets. Zip. I waited about a minute.
Again the display went dark but the hard drive did not go to sleep. When I touched the keyboard the display woke up right away but there was no change in the HD since it was already spinning.
Any suggestion as to what is wrong with my iMac? Why can't I get the hard drive to go to sleep even when nothing is connected to it and even when I tell it go to sleep after X minutes of inactivity?
Thanks, Panther

IMac won't wake from sleep since Lion!

Since installing Lion my iMac (intel core 2Duo) won't wake from sleep properly using my wireless keyboard, trackpad or magic mouse! I haven't changed any settings and I have to hold down the power button to force shut down and then restart! Any help?? x

Hi all
Finally went to the Genius Bar to ask the question as nothing has worked. They said I needed to reset my PRAM. I did it (Following these instructions... http://support.apple.com/kb/ht1379 ) and it worked.
So relieved....it was really annoying me.
Hope this helps others with the same issue.
Thanks

HT1338 Imac won't wake from sleep when a facetime call comes in

My Imac will not awake from sleep when a FaceTime call comes in.

I've had this problem several times now, and I do no own MobileMe. I don't use any bluetooth peripherals, but I've noticed that the precursor to the problem is that my bluetooth icon in the menubar goes from normal to "Bluetooth Unavailable." Then at some point later on, I put the iMac to sleep and it won't wake up.
I've read elsewhere that the bluetooth unavailable problem may be connected to the power management unit, which may in turn explain what is going on with it not rebooting. But I'm not sure.
