My iMac won't stay asleep, or it will turn itself off when going to sleep

If I select Sleep from the Apple menu, the screen goes blank, the light waxes and wanes once and the computer wakes up again.
When I allow it go to sleep by itself (my screen saver comes on after being idle for 15 minutes, then it should go to sleep after being idle for 45 minutes), then the screen goes dark, the light waxes and wanes once and then the light stays out, the display stays dark and after a few seconds the fans start running at high speed. It won't wake up by mouse or keyboard, I have to hold the power button for a few seconds, until a faint click tells me it's truly shut down. Then I can restart. I have tried resetting the SMU twice and that did not make any difference. What else can I do to make my iMac behave?

IMac won't stay asleep

I recently installed Lion OS. When i try to put my iMac to sleep, it does so momentarily and then wakes up.

Had the exact same problem. The trusty old mid-2007 iMac refused to stay asleep, whether I pressed the power button (with "Allow power button to put the computer to sleep" checked) or chose "Sleep" from the Apple menu or let it sit for the "Computer sleep" interval. It would immediately wake up again in all cases.
The problem was somehow related to the powered USB hub itself. Removing USB devices from the hub one at a time made no difference. Unplugging the hub from the iMac solved the problem (but also made it impossible to use, as the wired Apple keyboard is plugged into that hub.)
The solution was powering down all accessories (including the USB hub) and the iMac, then turning on power to all accessories, letting them start up, then turning on the iMac. There may have been some interaction between the USB hub, the iMac's PMU, and/or the iMac's USB controller(s) that prevented the iMac from sleeping.
(Note: it might be very useful to follow the advice in this thread: https://discussions.apple.com/message/17050677#17050677, which will show the specific reason for the machine waking up. It may not be necessary to shut down all external devices to solve the problem.)

Imac turns off when going to sleep

Hi,
My imac shutdowns and I need to manually turn it back on - it has happened a few times now when I put my computer to sleep. Anything I can do to stop this? Should I be contacting Apple? Is this a big issue? Thanks Bethany

Do you get any lines like these around the time it happens?
Also, resetting the SMC might be a good thing to try:

After startup Mac will turn itself off and won't get into OSx

The start up chime sounds, then apple logo and process circle appear along with a slow process bar (loading osx?).
When the bar fills up it just shuts off every time after several tries.
I'd like to recover the data inside if possible, plase help.
Thanks

It could be, but open Disk Utility and see. If your drive is still there, you just need to erase it:
Install or Reinstall Mavericks or Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.

Won't stay asleep. How to troubleshoot?

My iMac won't stay asleep when either put to sleep or when it "falls asleep". I've attempted removing or turning off all peripherals with no luck. I've tried unchecking Wake for Network access (however, I use Logmein so this needs to remain on). Is there a system log I can inspect to see what's waking the computer up? The iMac is connected via LAN, Skype runs in the background as well as a few other scheduling apps (Chronosync for example).
Any thoughts?
Thanks.

Sounds like a background or scheduled process is the problem.

EMac won't stay asleep

All of a sudden, my eMac won't stay asleep. I've turned off all the settings in Energy Saver (including the Wake options for modem/LAN). I also have no USB or Firewire connections.
I've repaired permissions, optimized system, cleaned caches, and zapped the pram.
I've tested on/off my LAN. I've also tried unhooking my mouse and keyboard.
Here is the system and console log after I put it to sleep:

C2D 20" iMac, G4 1.33 iBook, 1Ghz eMac, G3 333 iMac (Blueberry) Mac OS X (10.4.8) 5G iPod, 2G 4GB Nano, 3G 20GB iPod, 512MB iPod Shuffle

This is for a Mac that won't sleep.
First, read things in Apple doc.#25801 on sleep settings.
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!

IMac 27 inch i5 won't stay asleep!!!

So starting this past Sunday my imac wouldn't stay asleep. i would wake up in the middle of the night to a bright display instead of the normal black screen, i'd put it back to sleep then an hour later back on. I tried getting rid of the wake on network. I even logged out then put it to sleep. It still wakes up.
I disabled external drives. The only bluetooth thing is the magic mouse. Oh and i disabled sharing too. I don't get why this just started happening. Any one have any insight/suggestions???

I even have free apple support, and must have called them 30 times about this, but to no avail. I think the reason that so many imacs do not stay asleep, me included, is because Apple does not want your computer to sleep. With the limited Mac viruses, and the advanced system, why would anyone ever need a repair, or a new mac. Unless your internal battery failed, over time, not allowing your mac to sleep. I think this is a way that Mac designed there imacs. I mean, see how long, you would last w/o any sleep. I had some problems wt my imac using leopard, but wt some work arounds, I got it to stay asleep. Then wt the Snow Leopard upgrade, it failed to stay asleep, no matter what I did. Until I surfed some. I'm not going to recommend any freeware in particular, since each user has different sleep issues. But if you do a search on google, there is a ton of freeware, that will make it sleep, and stay asleep. This should be much easier then lugging it to Apple, or throwing it out the window

My iMac won't stay connected to the internet, even though all other computers in my house stay connected

My iMac won't stay connected to the internet, even though all other computers in my house stay connected, and its connection is set up the same way my fiance's macbook is (his macbook is about three years older than my iMac). Every time my computer goes into sleep mode and I come back (even if it's mere seconds after giving the black screen) I have no internet connection. I discovered a workaround for it some time ago, but now that is working less and less, and now my computer randomly disconnects WHILE I'm actively using the internet. Just a few minutes ago, the connection refused to come back until I restarted my computer, even though once again all other computers in the house were connected. The workaround I discovered before and which doesn't work as reliably now, is to click opne Airport at the top right of the screen, click "Open Network Preferences," then click "Assist me," then click "Diagnostics," and wait for everything to turn green again, signalling a connection.

Let's check the quality of your connection since signal strength alone does not insure a good connection. The "bars" that you see at the top of the iMac screen are there pretty much for show.
Hold down the option key on the iMac while you click on the Apple icon at the upper left corner of your screen and select System Profiler
Look down the list of items at the left of the window until you find the setting for Network, then click on AirPort.
In the window to the right, look for any listings of your wireless network name. You may possibly see two listings for the wireless network name.
We need for you to list the information that you see for Signal / Noise. These will be negative numbers. Post back with your findings and we will continue.
In the meantime, please move any cordless phones that you have or any other electronic devices that are near the iMac as far away as possible from the iMac.
If the iMac is located in a corner or an enclosed area, give it as much room as possible since the wireless antenna is on the back of the iMac and it needs to be able to "see" the room.
Anything that you can do to minimize the number of obstructions like walls or furniture etc between the iMac and the wireless router will help the cause as well.

New Mac Pro won't stay asleep

Hi everyone. I took delivery of my new Mac Pro a few days ago. It's the highest spec model (12 core, 64gb memory, 2 x 6gb graphics and 1TB SSD). It's connected to two 30" screens and networked to a Windows storage server.
The problem I have is that it won't stay asleep. Basically after being asleep for a couple of minutes the screens suddenly come back on and the login window appears as though somebody has pressed a key. After a minute or so it goes back to sleep and then it wakes up again and continues in a cycle.
I have tried making sure all programs are closed and nothing is running at all but it still happens.
I just wonder if anyone else has had this issue or might know a solution?

Okay thanks for all the help guys, I've discovered what the problem is but not how to fix it.
I unplugged everything but the bare minimum and the computer stayed asleep just fine. I then plugged everything in one thing at a time and tested. The culprit was one of my screens! I have an NEC Spectraview Reference 301 screen. It worked just fine on my old Mac Pro but when this screen is powered up the new Mac Pro will not stay asleep for more than 1 minute. My other screen is an Apple Cinema display and this works just fine on its own.
The solution for now is that I have to remember to hit the power button on the NEC screen before I leave the computer. This is fine but I'd love to find out what's causing this issue so I don't have to remember every time! I'm thinking maybe the NEC has some built in power settings so I'm going to fiddle with them now. If anyone else has any further ideas I'd love to hear them!

Imac won't stay connected to wireless network

I recently moved and now my imac won't stay connected to my wireless network. Every other device connects just fine, so it's not the service, or the location, because devices are all in the same room.
Every time my computer goes to sleep it seems to completely forget how to connect to the internet. There is only one Network (mine) listed in preferred networks. The computer will connect only if I go to System Preferences and run through the Network Diagnostics to tell it exactly what to connect to. Each time it says my connection and internet are fine, which I know.
Please someone tell me how to get it to remember my network so I can stop going through the Diagnostics every time I want to use my internet.

Though all of these steps may or may not be needed, I'm including them all.

Power Mac G5 won't stay asleep

Hello,
I just bought a G5 dual 2.5ghz (june '04). It won't stay asleep. I put it to sleep and it always wakes up within 3 minutes or so. I have unplugged all peripherals except for the keyboard/mouse which are hooked-up to the back of the 20" ACD. On this machine i'm running 10.4.11
I have reset the PRAM, etc. and turned off all options in the energy saver box.
Is my motherboard fried? What else can I do?
Any help is greatly appreciated.
thanks
Dan

tsunami,
+*what does EIR not supported mean?????*+
That's a good question. I googled it but couldn't come up with anything logical.
Do you have an application in your Login Items that may be incompatible with Leopard? Check System Preferences>Accounts>Login Items. If there are some apps in there, it may be worth your while to jot them down, and then remove them from Login Items. After they've been removed try to sleep your computer. If it sleeps, then (if you need them), add them back in, one at a time, and keep testing to see if sleep is affected.
If the above doesn't work, create another account (I'd give it Admin Privileges) and log into it. Now try to sleep your computer. If it sleeps, you've got an issue (I hate that word) with your account...what, I don't know. You can either continue to try to locate and fix the problem, or (I suppose) you can move your data and settings to the new account....
I'm not sure where the point of diminishing returns is...It make take a fair amount of time and effort to copy your data and settings to a new account. I wonder if an archive and install would take the same amount of time, if you need to go that route...

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.

MacBook won't stay asleep & pploader going nuts

Last day or two I've noticed my MacBook won't stay asleep more than a few seconds at a time... very effing frustrating.
Aside from that not only does it not sleep, it actually acts up, the fans start running and the comp gets very hot. A quick check of Activity Monitor shows that "pploader" is what is making the fans spin... I'm guessing this also has something to do with the not staying asleep issue. Not a good situation.
FYI, I recently upgraded my hard drive and switched to the Opera browser.
Any ideas, advice? Please?
Thanks

The error that my icloud account is full and need more storage stays on the screen of my Ipad2. It won't allow me to get more, turn it off or do anything on it. Help!!

Reset: Hold the Sleep/Wake and Home buttons until the screen goes dark and the Apple logo appears
Then do some house cleaning in iCloud (or purchase more storage)
Settings > iCloud > Storage & Backup > Manage Storage > Select a device if more that one > Show All Apps and turn off some apps that you don't need or care to be backed up.
Also, connect to iTunes and empty your Camera Roll onto your computer. Photos & videos tend to eat up a lot of space.

IMac turned itself off and won't fully turn back on

My iMac turned itself off this morning; all I was doing was typing, nothing intensive. It wouldn't turn back on.
I first got a wired keyboard and mouse and tried resetting the SMC. No success.
Next I took out and put back in the RAM (and it was unplugged). After repeatedly pressing the power button, I got a single beep out of it. I personally don't think it was high enough of a pitch, but I read that it might've been because the computer didn't read any RAM.
I might've again taken the RAM out, this time also unplugged. After more repeated pressing, the fans came on, but then dead again.
The third time, the fans came on and half of the dong played, but it was cut off.
The forth time the dong fully played, but a second after, it turned off again.
All of these times involved unplugging the computer for a few seconds and then repeatedly pressing the power button; I might've taken the RAM out all of the times too, but I don't remember now.
Two or so weeks ago, I did have a kernal panic while I was editing in iPhoto, and I believe it's the first for my iMac. About a month and a half ago I had a graphics problem where using exposé to show all windows caused the whole screen to become jagged 'shards' of colour (it reminded me of broken pieces of glass). While a restart fixed both of these problems, the graphic problems are not new for this iMac (though I had never had the shard effect before).
Two more little things that I'm unsure if they're related: last night, it turned itself on from sleep, but it does this every other night, so I don't think last night's special; and every time I got it to turn on, I felt that I had to give the power button just a short burst of force, as if holding it for even half a second wouldn't get it to turn on.
Does this sound like the logic board, or less expensively, the power supply? Since it attempts to come on here and there but gets cut off, what does that say with respect to the logic board?
The computer turned one year in August 08, and there's no AppleCare. Even though the warranty's gone, would Apple have any negative view if I opened it up to get my HDD? I can get the screen off with three house suction cups; my HDD was last backed up four days ago, and of course, I had just typed about 3000 words for a story I'm working on between last night and this morning.
And lastly, if I make an appointment with the Apple Store (two hours from here...) and they want to take it in, will they take out my HDD right there and give it to me if I don't take it out? Four days is so tremendous in this situation. I will not part with my HDD.

Perhaps. While I guess they're certified, I still trust Apple the most. Also, if it is a logic board problem, and it is widespread, hopefully this could be free. I don't know how a reseller would handle such a situation. I just want a file off my HDD!
I can confirm that it never really powers on unless it's been unplugged for at least a few seconds. So far, the longer it's been unplugged, the longer it stayed on. There were hours between the times I almost got into my account, and then the login window.
I again switched the MacBook and iMac's RAM, but doing this makes a senseless result. The MB's light simply stays on (no fans or screen, but when I turn it off, I do hear it 'de-whir'), and the iMac just quickly turns on and then off, as it has been after a 5-30 second unplugging session.
I guess this is the rebellion of a Revision A machine.

My iMac won't stay asleep, or it will turn itself off when going to sleep
