MBPro and monitor not staying asleep; new problem

Suddenly my new MBPro and its 24" monitor won't stay asleep!.
I ordinarily use the 24" monitor, leaving lid on my MBPro shut.
At night, I choose 'sleep" from the Apple menu and the mac and monitor sleep.
Suddenly, past couple of days, when I do this,
-monitor sleeps and then within seconds it pops awake
-If I raise the lid of my MBPro, the monitor of the laptop is black, does not come up until I use Software preferences to "detect display"
-only way I can keep both monitor and mac asleep is if I leave the lid of my MBPro up, then choose sleep, then the mac and monitor rest.
I suspect one of the recent sofware updates may be doing this.
Anyone else experiencing this?
Should I reset the PMU on the monitor?
(Does anyone know the precise steps todo this; I know about removing the battery and holding power key for 5 seconds but have been given different advice on removing power cord or not)

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.

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 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.

IMac will not stay asleep! Widgets are to blame!!

Thought I'd share this piece of information, it might be in here somewhere but I could not find the resolution. Here goes:
Recently, my iMac would not stay asleep, my screensaver would not even start. If I forced my screensaver with expose, it would not fall asleep after the specified time in system preferences>energy saver. If i selected "sleep" from the apple menu, it would wake back up after 2-10 seconds. I just recently set up my airport network and thought about that, nothing. I thought it might be a program, so I shut down all my programs, and still nothing. I was so frustrated so I decided to search the forums. I found a post that suggested to look at the Activity Monitor (apps>utilities>activity monitor). So I did that and guess what: the activity keeping my imac from sleeping was DASHBOARD. I had a great widget that had swimming fish, only the fish swam all the time, and prevent my computer from sleeping. Keep that in mind when you are adding widgets.
Problem solved, and now my iMac sleeps at night, and so do I! (come on, it was too easy to pass :D)

Good to hear.
Enjoy your Mac

My new Macbook pro retina 2013 won't stay asleep

When I put it to sleep by closing the cover or by selecting sleep, it sometimes stays asleep, but mostly not. The worst thing is I sometimes find it with the fan running on high, very hot, and when I lift the lid and log in (it requires me to loging twice), I check the Activity Monitor and it shows at the top, using the CPU, 5 "ManagedClient" processes, each using 100% of the CPU. Something is very wrong. Several times after being asleep, it had obviously restarted and as message on a plain screen said "Your computer was restarted because of a problem" - still an issue but not as bad as the first one I described. I also find, after any and every problem - which threre have been many of, the computer will not restart or shut down. It goes as far as the spinning wheel and stays there and I have to Force power down.
Any expert help here would be really appreciated.
Thanks,
Fred

It seems Mavericks has quite a few bugs, including this one. This problem did not occur in previous versions of the OS, even with the same hardware.

Macbook won't stay asleep

Since updating to Leopard a few months ago, my Macbook will not stay asleep. It goes to sleep and wakes moments later. This keeps happening until I have to shutdown.
I brough it to an Apple Genius - he checked all my settings, diabled my infrared and bluetooth. He also checked some log which noted that the wake episodes are being caused by "usb port activity" - but nothing was ever connected to this computer. There's been no change - the thing will not stay asleep!
Any ideas? Again - there are NO settings telling it to wake up at certain times.

Try this:
1) Close all running programs
2) Go to *Activity Monitor* and locate loginwindow under Process Name
3) Click on loginwindow to highlight it and click *Quit Process* in the Tool Bar. A window comes up that instructs you to *Force Quit* - do that.
4) Next you will be returned to the Login Screen and do so to bring up OS X.
Now try closing your computer screen and see if it sleeps.
Hope this helps -GDF

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

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 G5 wont stay asleep

I have just recently restored my iMac and am having the same issue with sleeping as I did last christmas when I got it; It wont stay asleep! I called AppleCare last year and they had me delete some com.autowake. something something in the system folder and I don't remember what it was. Since I don't have AppleCare anymore, I don't know what to do.
Does anyone know how to correct this?

I called AppleCare last year and they had me delete some com.autowake. something something in the system folder and I don't remember what it was.
It was probably the file com.apple.autowake.plist in the folder /Library/Preferences/SystemConfiguration/.

Won't stay asleep!

As of a few days ago, my MacBook Pro doens't want to stay asleep.
Everytime I've closed my machine and left it for a while, when I come back it's burning hot. I open it and it is having some weird problems with the screen lock (doesn't give me the password protect immediately, have to sometimes open and close the machine a few times to get it, sometimes it goes to sleep immediately after I authenticate, etc.).
If I sit and listen, a few minutes after I shut it I hear the CD sound that I would normally hear when it wakes. It does this repeatedly. So, it seems to be going to sleep, but waking up regularly.
I have turned off appletalk and turned off the "wake on admin" stuff.
I have no idea what else would be waking it.

I had a similar situation (I have my own thread about it,) that I finally traced to my USB 2.0-connected ExpressCard flash memory reader. If the reader was in the ExpressCard slot, the MacBook would behave exactly as mentioned here. It would LOOK like it was going to sleep, but it would wake right back up if open, or just get itself blazingly hot while draining the battery if closed. Removing the reader, and it sleeps just fine.
Do you (any of you that have the problem,) have any peripherals plugged in? If so, try going to sleep with everything unplugged. If that solves it, then it's the peripheral. If not, then time to call Apple. (I called Apple, and never did get a fix. But, I did report it when the MBP had only been in customer hands for 2 days, so even the guys at the local Apple Store hadn't worked on one yet.)

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.

Sleep will not stay asleep

I have a Mac Mini and when I put the machine to sleep, via the Menu sleep option, it goes to sleep and then wakes itself up about a minute later.
How can I get the Mac to stay asleep until I want it to wake?

It is possible that the "wakeup" is being caused by perceived activity on the connections to peripherals.
If you have a Bluetooth keyboard and/or mouse there is a possibility that they are sending periodic "messages" to the mini, or in a perverse logic some BT devices may send a message when they are about to go into sleep mode themselves (ie. "here's a disconnect request") which could well be about a minute after you've put the mini to sleep.
If you have any USB attached devices there is a similar possibility. In addition, I have noticed that USB cables that are near power cables pick up EM interference from power surges (eg. switching on a desk lamp) so you might want to check for the proximity of other cables.
Hope that helps.

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 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
