IMac display won't stay asleep while encoding with iDVD

My iMac's display refuses to stay in sleep mode while I am encoding a project in iDVD. (Note that I'm referring to sleeping the display, not the entire computer.) I encode large projects overnight, and I am concerned about possible burn-in, the annoyance of the unwanted light when I'm trying to sleep, and the waste of energy. A search of the archives reveals a long history of the same problem which unfortunately has remained unsolved.
I have tried the following with no success:
1. Ruled out accidental mouse/keyboard strokes as the problem
2. Used Hot Corners to initiate sleep (wakes back up after 5 seconds)
3. Setting the sleep display timer to 1 minute in the Energy Saving settings
4. 3rd party app and widget "Sleep Display" (only works for 10.4 Tiger apparently)
Does anyone have any new ideas about this bug/problem? Does it only affect iMacs?
Thanks

How can you be sure? It may be some system operation that's doing it.
This may also prevent the display from sleeping, but the next time you're doing this you might launch Activity Monitor and order the process list by CPU. Then when the display wakes up, note what processes (besides the DVD encoding software) are using non-trivial amounts of CPU time.

IMac display doesn't stay asleep when hot corner activated

Hi,
I'm having the same problem mentioned in this archived thread from three years ago:
https://discussions.apple.com/thread/1323073?start=0&tstart=0
I have an Intel 27" iMac that I bought brand new last year. I have a hot corner set to sleep the display, but after it's activated it usually comes back on after a few seconds. It's really frustrating.
If it's just mouse jitters (I have the wireless Magic Mouse that came with the iMac), I don't understand why the hot corner area is so small. It seems like it's just a pixel large. Is there any way to make the hot corner area bigger so the mouse has to be moved a wider distance to come out of the hot corner?
Or if it's certain programs activating the display, how do I figure out which programs are doing it and is there any way to prevent all programs from doing that? If I'm choosing to sleep my display, I want it to stay that way and I don't want it to come on even if I have an iCal reminder.

Imac display won't power up or stay on when it does

imac display won't power up or stay on when it does

Have you checked the Energy Saver settings? System Preferences / Energy Saver.
If the settings are what you want, you can try this. Change them to anything at all then change them back to what you want. The restart the computer and reset the PRAM.
Shut down your Mac.
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 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.

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:

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!

MBP display won't stay off, wakes from sleep

I have a newish 15" MBP, 1680 display, hooked up to a Dell external monitor when it's at home. When I go to bed I cut power to the display via control-shift-eject, but generally don't put the computer to sleep overnight.
With this new machine, after it's been running for a while (as little as a day, or as long as a couple weeks), the displays will come on again in the night. Once this happens, the displays won't stay off for longer than about five seconds. If I then put the machine to sleep, it'll wake itself up minutes or hours later (generally not long enough to miss a Time Machine interval). The only cure is rebooting.
I tried an SMC reset, but that fix only lasted about as long as any other reboot.
I've since tried systematically removing every peripheral (a USB hub, the external display, any directly-connected iOS devices) and testing display-off after each; no change. I've turned off my Bluetooth keyboard and mouse, then disabled Bluetooth on the computer, turned off wifi, quit every menu extra (jitouch, Viscosity, Dropbox, Pastebot, Fastscripts, Transmit, Teleport), and quit every running application. The problem remains repeatable after every step.
It's repeatable at the moment — any suggestions for other things to try, preferably short of the reboot which temporarily masks the problem? I'm a little concerned that it's going to manifest at some point while I have the laptop sitting in a bag, which will then cook itself.
I'm on 10.6.4 now, the problem started on 10.6.3.
Thanks.

Try checking the system logs in Applications/Utilities/Console.app for clues. The entries carry time stamps. Usually a wake event will leave some trace. By matching time stamps to the time of occurrence you may find the culprit.

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.

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!

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

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. 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.

How can I wipe a drive on an old iMac that won't stay on long enough to complete the task?

Do you have access to another Mac? If so contact the two via a Firewire cable, boot your problem Mac into Target Disk Mode, Transferring files between two computers using FireWire,, and try to use Disk Utiltiy from the second Mac to reformat and erase your hard drive.

Have an iMac G5 won't stay connect to the internet

Have an iMac G5 won't stay connect to the internet by cable/ethernet for more than minute or so. After I reboot the Verizon modem I have five green lights, ethernet, network settings, isp, internet server all green. Open browser, internet, server go red. Somehow my grand-daughter downloaded some program that gives me a world back ground "Not licensed evaluation use only". If I change the background the world background comes right back.

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

Sleep Display not staying asleep when encoding video

Hello,
I am looking for a way to turn the display off and KEEP it off with applications running as normal, until I want to wake it up. It is not always staying asleep.
I have a hot corner set up so that I can instantly turn my iMac display off (including the backlight). This works fine most of the time, but when running certain applications, activating sleep display works for a few seconds then stops working and the screen comes back to life.
Example applications which cause this are iTunes when encoding a video (e.g. converting a movie to iPod format), iSquint when encoding video, iDVD when encoding and burning a DVD - seems to be anything that makes heavy use of the processor.
I have tried all sorts of things to get around this:
1. setting the sleep display timer to 1 minute in the Energy Saving settings
2. 3rd party application and widget "Sleep Display" (http://linestreet.googlepages.com/home) which claims to make the display go to sleep and STAY asleep, suggesting "This version may work for people who experienced the monitor going off then coming right back on" - which indicates that it's not just me having the problem. This "Sleep Display" application doesn't work with Leopard though; the author acknowledges this and suggests he will update it if he upgrades to 10.5
3. different application - http://www.imalc.com/Site/SleepDisplay.html - this does the same as the hot corner and wakes up within a few seconds
4. sleep display tool in Dockables - same problem
5. "shades" system preference add-on, this makes the screen black and keeps it black but doesn't turn the backlight off
6. tried hiding the offending application, moving it to another space - nothing seems to work!
7. covering the imac with clothes - not ideal!
Thanks for your help!
Jim
P.S. the screensaver does stay on - so whatever is waking the sleep display isn't disturbing the screen saver - this suggests to me it's a bug. Obviously a black screensaver isn't the solution though - the backlight is still on.

I've got a very the similar problem. Brand new iMac 24" that shipped with Leopard -- my first Mac after jumping ship fom the Windoze side.
I had iTunes updating it's album artwork and since it was taking a while, I went to bed. When I turned out my light, I realized the screen had not yet gone to sleep (a good 15 minutes after it should have). So I set up a Hot Corner to put the display to sleep. When I put the mouse there, the monitor would go to sleep, but wake up within 10 seconds. At first I thought it was just the mouse moving as I walked away, but it wasn't.
I ended up turning the computer off because the big beautiful screen was throwing too much light. Since, I rarely turn my computers off and they're usually doing SOMETHING, this is really annoying.
Admittedly, I haven't tried some othe the potential solutions above, but this has to be the same bug. Screen saver stays on, monitor comes out of sleep.
Any help would be.....well.....helpful.

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

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.)
