Will not go to sleep, or will repeatedly wake up.

My Macbook Pro has developed a new problem over the last few days. When I close it, it will either not go to sleep, with the Apple logo still lit after 10 minutes of waiting (and upon opening, the screen is still on), or will go to sleep, but wake up every 10 minutes, then go back to sleep. When it does this I can hear the noises from the optical drive it makes when it comes out of sleep.
I have tried restarting, and all firmware and software is up to date. Any help is appreciated...

I have a 2.2GHz MacBook Pro and have the exact same problem. It's driving me nuts!

My macbook pro 2.0 early 2011 will not go to sleep with the power source connected. only enters sleep mode when running on battery. Someone did this happen, and it could solve?

Alo, my Macbook pro i7 2 GHz Intel Core i7 (early 2011) will not go to sleep with the power source connected. only enters sleep mode when running on battery. Someone did this happen, and it could solve?

There is no output from that command line? Maybe the pid changed.
I'll repeat what I am trying to find out...
1. You do a pmset -g on the terminal.
2. The output from that pmset should have a line that says "sleep 0 (imposed by n)" where n is some number.
3. The ps ax | grep n is supposed to display what the process associated with n is.
It's the output from step 3 that should indicate what is causing you not to sleep.
But speaking of sleep, that's where I am going.

Macbook with external monitor, running Lion, will not go to sleep

I have software version 10.7.5 and my macbook will not go to sleep on its own. It will go to sleep if I hit the power button and then tell it to go to sleep. I have turned off all sharing and I have set the preferences to sleep after 15 minutes. Yet, I hear the hard drive spinning all of the time. Any suggestions??

Have you reset the SMC? If not, try that.

If you've done that, and it didn't help, then launch the Terminal application by entering the first few letters of its name into a Spotlight search. Copy or drag -- do not type -- the line below into the Terminal window, then press return:
pmset -g
Post any lines of output that appear below what you entered -- the text, please, not a screenshot. Then repeat with the following line:

LaserJet Pro MFP M127fw will not go to sleep

I just bought a LaserJet Pro MFP M127fw. Through the LCD Control Panel I set it up to go to sleep after 5 minutes. It will not go to sleep, the LCD panel is always on. I did the following from the LCD panel: Setup Menu >>System Setup >> Energy Settings >> Sleep/Auto Off after >> 5 Minutes Printer is connected via wireless. I'm using this printer on a Mac OSX 10.9 (Mavericks) and have installed the latest driver software from HP Support website. Anyone has noticed this problem and is there a solution to it? Thanks.

Hi tuanomsoc, I hope you had a good weekend!
The printer has a built-in surge protector, so by plugging into a surge protector or a power bar, it can cause power drains that affect the functionality. I would recommend the post below by , who has provided a helpful write-up on this exact question: Power Supply Related Issues Please let me know if you have any questions. Thanks for posting on the HP Forums!

C55Dt running Windows 8.1 will not go to sleep or turn off when lid is shut

Toshiba Model C55Dt will not go into sleep mode when I shut the lid. Only about 10 months old....will not turn off, either. I have checked and power settings are properly set. All 3 lights stay on in front....battery charge, power, and computer usage. Have checked Task Manager and nothing unusual running. Any help appreciated.

Which Satellite C55Dt ? There is a label on the bottom.
Would it be a problem to reinstall your desktop applications if the data files were undisturbed?

My Macbook Pro (mid 2012) will not go to sleep

Hi - looking forward to your help!
My Macbook Pro simply will not go to sleep - not by shutting the lid or pressing the sleep button in the Apple dropdown.
There are no random apps that are preventing it from sleeping - I have checked after looking at a blog and using "terminal".
The poor thing is getting really tired and bad tempered, so your help will be appreciated!
Many thanks!

Hope info from this article is helpful.

My Macbook Pro (mid 2007) will not go to sleep.

When I close the lid, select sleep from the  menu, or push the power button, and select "sleep" my MBP will not go to sleep as it ussually does. It has been doing this since I performed the last set of software updates (Mac OS X Lion 10.7.4 (11E53) about a week ago.
I need help... this is annoying

This is for a Mac that won't sleep.
Here is Apple's KB article HT1776 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 receive 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 Receive Faxes On This Computer box.
If that doesn't 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.
Some have resolved sleep issue by downloading the Combo update, from this site (yours may be corrupt), not Software Update disconnect all firewire + USB devices except keyboard + mouse,Repair Permissions, re-install update, Repair Permissions again + try
USER TIPS……..
Check in System Preferences > Energy Saver is "Wake for network access" checked? If so, uncheck it.
One user reported, " I couldn't make my macbook pro to go to sleep because I had my wireless headphone receiver still plugged in. I unplugged it and then it went to sleep."
Also, if you have an External Western Digital (WD) hard drive and have installed WDDMService and WDSmartWareD on your Mac, it may not sleep. Fix is to un-install those....you don't need them to use the drive.
"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?"
One 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 card.
Also, here is Apple KB article TA2469 about PCI cards and sleep.
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.
"I have a Canon printer(shared) and my imac would not sleep. I opened up printer/fax in system prefs and noticed it said the printer was in use when it was off. Opened up the printer queue and noticed about 7 pending documents. Deleted them all and now it sleeps. Check the printer queue!"
One user has had success, after trying all these tips, using an App. called PleaseSleep. I've never used it though.
Good Luck! 

2007 macbook pro will not go to sleep...

Whether i close the lid or use the command it will not go to sleep. If i close the lid the little white light in front goes on bright and stays. If i use the command the white light goes on dim & stays that way. I've tried resetting the SMU (?) by removing the battery and holding the power button down for 5 sec, but no luck.
Anyone have any other suggestions?

OK.
Right side of your original post under More Like This, there is an answered question marked with a green
Check mark. Check it out . It is about Mac not sleeping when charger attached.
It is about file sharing being on.
Best.

IBook G4 will not go to sleep

Hello Everyone,
This is a problem I've been having for about a year but now I'm finally trying to fix it. My iBook G4 will not go to sleep. It doesn't matter what method of putting it to sleep I use. Using software to select sleep, or the power button and clicking on sleep don't do anything. Closing the lid just turns off the screen, but then the computer doesn't have power if I open it much later and is still running if I open it quickly.
After trying to put the computer to sleep, it takes several minutes to turn off, so I'm guessing something is screwed up as a result of trying to make it sleep. Additionally, although possibly not related, sometimes if just left on but unused, it will lock up so that it doesn't respond to anything (no keyboard inputs and the screen is dark) but the power is still on (caps lock light will turn on and off).
Here is what I have tried to fix the problem so far:
Reset PMU
Reset PRAM/NVRAM
Ran techtool deluxe - says everything is OK
tried without additional memory (which came with the ibook) - didn't help
tried without airport extreme card (which came with the ibook) - didn't help
tried booting in safe mode - didn't help
tried putting it to sleep when logged out - didn't help
i tried to run the diagnostic cd that came with the ibook, but it gave me error messages (both with and without extra memory)
Invalid memory access at %SRR0:00cadcbc
%SRR1:00003030
and had a flashing file folder with mac symbol and a "?"
i reformatted the hard drive and reinstalled 10.4.11 (through CD and software update) - didn't help
Does anyone have any thoughts on what else I can try to figure out the problem? The only thing I have thought of is that maybe one of the updates might be the problem, since when I got the ibook it worked wonderfully. (Sadly, when reinstalling I didn't think to check if it would sleep after each update).
Is there a way (other than safe mode) to find out if it is a 3rd party software problem or an OS problem?
Is there any way I can get the mac diagnostic CD to work so maybe that could tell me something?
Should I just stop calling it a laptop and use it as a desktop where sleeping isn't as important?
Thanks for any help you can give!!!

Hey Spherical (cool name but weird),
Now realized that I don't know the CPU speed and size of your iBook but it probably doesn't matter since they're all pretty much the same but then again....
Here's something from that post that I referenced:
It's official designation is PMU99.
http://developer.apple.com/documentation/Hardware/DeveloperNotes/Macintosh_CPUs-G4/12inchPowerBookG4/2_Architecture/chapter_3_section4.html
"Power Control IC
The power manager IC in the 12-inch PowerBook G4 is a Mitsubishi M16C/62F microprocessor, also called the PMU99. It operates with its own RAM and ROM. The functions of the PMU99 include:
*controlling the sleep and power on and off sequences
*real time clock
*controlling power to the other ICs
*monitoring the battery charge level
*controlling battery charging
*supporting the interface to the built-in keyboard ( and also the trackpad )
The PMU99 also provides the hardware interface to the keyboard. Software in the PMU99 IC scans the keyboard, then sends the data to the system in packets like those from the ADB. To the system, the keyboard behaves as if they were ADB devices"
So try detaching the keyboard and trackpad from the logic board. Be careful doing this. Email me for instructions. Be especially careful with the trackpad flex as it's real easy to mess up that socket. While you're doing that inspect the connectors/sockets for any evidence of liquid spills .

Mac will not stay in sleep mode

My IMac running system 10.5.8 will not remain in sleep mode. I have tried closing all running applications and this makes no difference. After restarting the computer it seemed to function correctly for a short time then once again would not remain in sleep mode. The energy saver has no wake options set.

Here are 3 shots...of course things keep moving but I think I got most off.

P67A-GD65 will only enter S1 sleep, will not do S3 sleep

I am currently running the 1.7 BIOS. It seems that, although I have the S3 option enabled under the BIOS, my machine will not enter S3 sleep. It will only go to S1. Is there already a BIOS update that addresses this? This is the ONLY problem I have with this board, otherwise I am totally delighted with it. Thanks in advance.

I had a similar problem with "turbo boost" in my BIOS. With TB enabled it will not wake up from S3 sleep. With TB disabled no problems with waking up from S3 sleep. This problem materialized when I "upgraded" from the OEM bios to the latest BIOS. To this day I can reproduce the problem at will. As requested by the moderators here I sent an email to MSI to let them know, but I never heard back from them.

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.

Will not go to sleep, or will repeatedly wake up.
