My macbook won't sleep

Recently my MacBook won't go to sleep. If I close the lid or choose sleep from the menu it shuts down and restarts. When it is closed, it restarts continuously until it's opened again. I hadn't downloaded anything new before the problem started, and all of my programs are as up to date as they can be (I'm on the Tiger OS so I can only update programs that work with that old of an OS). My battery was also not holding charge like it should so I got it replaced. That didn't help the sleep issue though.

Hi. Please check if your bluetooth is on. This might cause some computers not to sleep because it keeps on looking for bluetooth devices. Also you can try resetting the SMC and see if that helps. This goes for the battery as well. You might want to put more info regarding your battery though. Use system profiler to get the info and post it. Here are the steps for resetting your SMC.

My MacBook won't sleep and I'm forced to reboot...

For the past two weeks, every other time I close my MacBook it will either sleep or it will not sleep. When it won't sleep, the light on the apple turns off but the little indicator light stays on and I can hear the fans whirring. When it stays on instead of sleeping, the screen is frozen and black and I'm forced to turn the power off then turn it back on. I've tried a few things including taking the battery out and holding down the power button but nothing seems to be working. My nearest Apple approved service provider is about an hour away and I don't mind taking it but if I can fix it without making the drive that would be awesome. If there are some specific things you need to find out my computer let me know and I'll fill you in. Any help would be very much appreciated.

Failure to sleep can be caused by hardware or software. To troubleshoot the problem you'll want to make sure nothing is connected to the computer but the power adapter since a USB or FireWire device might be the cause. Your computer came with a hardware diagnostic disc - either it is part of your installation DVD or it is a separate disc. Boot up with that disc and let it run. If it shows a problem you know you need to make a trip to the shop. If not, we can't positively eliminate hardware but we'll move on.
You'll need to create a new user account, after which you should shut down the computer and then restart and log in directly to the new account. This will eliminate any start-up items that might be causing the problem as well as any munged preferences that might be the cause.
If the computer continues to show shutdown issues you'll want to look at: 1) 3rd party drivers such as all-in-one printers and scanners - uninstall, restart and try again, 2) RAM upgrades - remove and try again, 3) an OS reinstall (which I've saved for next to last), 4) computer hardware. If you get to the OS reinstall, I'd recommend that you fully back up the computer and then erase the hard drive, reinstall the OS, and immediately try sleeping the computer.
Shutdown and wakeup issues are the two problems I hate dealing with most.

Macbook won't sleep or wake on command, overheats

I seem to have a sleeping and overheating problem with my 13" aluminum late-2008 edition 13" MacBook (I bought it exactly 4 years ago).
When I put my computer into sleep mode, be it by shutting the lid or selecting the sleep mode, it doesn't seem to stay asleep for long. I'll hear it running, it'll get extremely hot (whether or not the fans turn on seems to be a crapshoot). If I let it sleep longer than a couple minutes, the battery will run out, completely. Half the time when I turn the computer back on after plugging it back in, it doesn't respond right away and I'll have to force a reboot.
Other than sleep and possibly fan issues, the computer is running fine. No other complaints. Already took the battery out and reset the SMC. Not convinced that did anything worthwhile.
Help?

Hi there kbuckle!
I have an article for you that can help you troubleshoot your computer's sleep issue. That article is specific to Mountain Lion, and can be found right here:
OS X Mountain Lion: If your Mac won’t go to or stay in sleep
http://support.apple.com/kb/PH11080
Additionally, this older article might have some further troubleshooting steps for you, but it is more geared toward Snow Leopard and other older operating systems:

Hope this helps. Thanks for using the Apple Support Communities!

MacBook won't SLEEP properly?

My MacBook is custom set to go to the screensaver after 3 minutes and then the display is set to go to sleep after 4 minutes and it is set to ask for a password to wake from sleep or screensaver. Anyway, sometimes I'll walk away from my computer for a long amount of time (maybe an hour or two) and when I come back the screen will be all black so I assume it's asleep. However, when I tap the keyboard it goes right back into OSX without asking for a password or anything. Is it suppsoed to be like this or is my OSX messed up? Thanks.

This is purely anecdotal. I can't say it will work for you. My problem was similar, being that after closing the lid, the apple logo would light up and then go out periodically, but with my MB, I would also hear the cdrom eject. When I opened it back up, the thing would boot up as though I had restarted it. This happened every minute or two nutil I opened it back up or powered it off completely. To solve it, I booted off my OS X instll disk and ran an archive and install OS X. Then I ran Software Update several times until the OS was current again. Now there are no more reboots and I didn't have to erase my data. My applications, emails, photos, desktop settings and everything are still there. I'm also using Bootcamp and didn't have to erase that partition. That still works fine too. The only thing that I know of that I'll have to reinstall is Parallels Desktop where I run a virtual Windows PC at the same time as OS X. But, the Virtual Disk Images are fine, so I won't lose any info there after I reinstall the Parallels program.
I hope this reply is helpful. I was nervous about reinstalling, but I couldn't accept not being able to put the MB in sleep mode. I pretty much never turn it off.

Macbook won't Sleep or Shut Down

I just got my Macbook on Friday and it's great apart from the fact it won't shutdown or go to sleep.
When I try to shut it down, either by the power button or the menu, it just restarts.
When I close the lid or select Sleep from the menu the display turns off, the sleep light pulses once and then it kicks back into life. It's also accompanied by a drive access noise. Is this a common problem or am I going to have to send my Macbook back?
I've tried doing a software update which hasn't solved the problem and there are no USB devices attached.

Do a search for Sleep. You will find such as this

I suspect there is some simple fix, but getting Apple Support/Genius to do it would be best.

HELP!! Macbook won't sleep/hibernate

This is a Macbook (Intel Core Duo) purchased in August of 06. I'm new to Macs and don't know how to troubleshoot them. I need to find a solution for this problem!
Problem:
At times my bluetooth is working fine, but MOST of the time it says Bluetooth:Not Available. I don't use bluetooth hardly at all, but this is keeping my Macbook from going to sleep.
When it says "not available" and I shut the lid to put the Mac to sleep, the computer acts like it's going to sleep, then the apple light flashes and the cd drive spins, then it acts like it tries to sleep again. This continues until you open the computer back up and wait for bluetooth to become available.
I've tried multiple things: force shutdown, removing the battery for minutes, reset the PMU, trash the bluetooth plist file then reset the PMU, and I have searched Apple's site for days without success. Does the hardware just need to be replaced? If so, do I have to take it somewhere or can they ship you the part if its under warranty? I don't live anywhere near an Apple dealer/repair. HELP!!

I assume you have tried to simply turn Bluetooth off since you don't use it? (preferences->bluetooth->settings->turn bluetooth off).
If you can't resolve the problem on your own you should call AppleCare. Unless you bought an Applecare agreement you're probably out of the 90 day telephone support period. They'll still talk to you but if it turns out not be a warranty problem you'll have to pay for the service call.
If they determine that it is a warranty problem they just ship you a box to put your Macbook in. You ship it back, they fix it and then ship to back to your house. There's no need to drive to an Apple dealer.
My experience with laptop computers (Apples, Dells and Thinkpads) is that you should always get support agreements with them. A single out-of-warranty repair makes it worthwhile.

Macbook won't sleep with power adapter plugged in

Hi,
My Macbook has stopped going to sleep if the power adapter is plugged in.
I have the power adapter energy setting to sleep after 30 minutes. When I got the Macbook (about a month ago) the thing would sleep until I pressed the spacebar.
Now, the screen blanks but otherwise the Mac remains awake.
If I close the lid the Mac immediately goes to sleep.
I have reset the SMU but this didn't fix the problem. I also checked disk permissions and verified the disk in Disk Utility - all good.
Suggestions?
Thanks,
John

my MacBook has also stopped going to sleep with the power adapter plugged in or when using battery power, unless I close the lid. Did you ever figure out the problem? Did you try calling Apple Care?
thanks,
Liz

2006 MacBook won't sleep

When I tell my 2006 MacBook to sleep, the screen turns black for a few seconds, then the computer wakes up.
When I close the book, after a few seconds, the machine makes the same noise as when it does when it wakes up. What's going on? What can I do?

Macbook won't sleep

My Macbook wont sleep, therefore it drains all power. When I shut the lid of the computer, it acts like it is going to sleep, then after about 10 seconds the apple light flashes and the cd drive spins. It repeats this process until the battery drains.
I also have been having trouble with my bluetooth being shown as "not available". I keep bluetooth off, but it always says "not available" and there is nothing I can do to fix this. I'm thinking the two problems are connected! Another thing that seems weird is, it seems the bluetooth is NOT AVAILABLE when the battery is under 50% charged, then AVAILABLE once the battery has a charge.
Any help would be greatly appreciated since I'm new to Macs. Thanks!

OK, sounds like PMU. Call Apple, and have them tell you how to reset. 800-275-2273

Macbook Pro won't sleep after updating to 10.4.11

Hi,
I just updated to 10.4.11 reluctantly from 10.4.9 as whenever I do update I always have issues...I basically just went to software update last week and updated to everything I could. I've just been reading the forums and noted that updating is not always that easy...
Well basically my computer won't sleep if the lid is left open, this is IMMENSELY annoying since I often leave my desk to work on drawings, and I don't want energy being wasted like it is at the minute. Call me picky but I just want my computer to work.
I've reseted the PRAM, (option, alt, p and r), closed all applications, etc, but no luck...
Its a 2.2ghz MacBook pro, 2GB. Thank you in advance
Neal

The important thing for the future imho, is to always Repair Permissions before & after any update... seems to ward off most of these problems. Of course that is only good if the disk is Verified once in awhile.
Using Disk Utility in Mac OS X 10.4.3 or later to verify or repair disks...

About Disk Utility's Repair Disk Permissions feature...

In fact I'd start with those 2 now, if that doesn't help you may need to reapply some updates by getting them directly from apple>downloads.

Macbook Pro won't sleep

I have this setup: a MacBook Pro running Mountain Lion, an external 27" cinema display, a bluetooth apple keyboard and a bluetooth magic mouse.
The MacBook Pro runs with the lid closed.
It looks like the computer won't sleep anymore. It stays on for days when not using it. In my settings I have set I want the computer to sleep after 15 minutes of inactivity.
I prefer to switch off the keyboard and mouse when I'm away from my computer, so I can't use the Apple menu or shortcuts to make the computer sleep.
Any idea?

i am pretty sure this is because you have it connected to an external display. i am not sure if there is a workaround for this.

MacBook Pro won't sleep with external monitor

Hello,
have a problem. I'm using external monitor with my MacBook Pro. If I close the lid, I see all windows on external monitor and Yosemite won't sleep. Can you help me please? My external monitor is Samsung 21.5" and I'm connecting it to MacBook Pro via DVI.
Thank you

Macbook Pro won't sleep properly.

Hello;
I have a problem with my mid 2009 13'' MacBook Pro that won't sleep properly.
Whenever I close the lid, or chose ->Sleep, it takes a few seconds and the system sleeps (fan off, led fading off) , but INMEDIATELY after just a few miliseconds, the system wakes up again (fan on, led on, hdd spinning).
This sequence happens again and again indefinitely (sleeps / wake / sleeps / wake, and so on...)
Then I open the lid and everything works as expected.
So far I tried all this, with no luck:
- I've installed a clean Mountain Lion from scratch.
- The system is untoched: no new apps installed, no new drivers installed.
- All sharings are disabled.
- Bluetooth is disabled.
- Infrared port is disabled.
- There's nothing attached to the computer except from the magsafe cable.
- There are no background processes preventing the system from sleep (checked using "pmset -g assertions")
- There is no disc loaded in the optical unit.
- "Wake for network access" is disabled in Preferences->Energy Saver.
- SMC y PRAM reseted several times.
As you can see, I don't know what else to try...
I would REALLY appreciate any help or suggerence.
Thanks in advance,
Nicolas.

A SMC will not have any results with this, in my past experince. Surprisingly the loginin items is the usual culprit. Try option, command, delete (don't hold these keys ,just press them)and wait till it goes to sleep, and stays that way. Then if it stays aslep try closing the lid. Disconnect all peropherals. Try system preferences>energy saver, make sure comouter sleep is ot set to never, as well as the display on both power adapter and battery. On the same pane, click schedule and make sure the start up or wake is not clicked. Also try a Ssfe boot: Power off, power back on holding the shift key, coninue to hold the shift key till you see the progress bar.This will disable all 3rd party software (it some times fixes some stufff) try the sleep menu under the Apple, or the option,command,delete. Hope this offers some help. If yourMBP is new, less thsn 1 year old, or you have Applecare, I would let them deal with it. You have a warranty,USE IT! All the best
Close all applications/operations.
You ca try a pram reset for the heck of it, in case there is somrthing strange in there that needs to be flushed.
Pram reset: Power off, power on, hold the following keys before the start chime. option,comman,P,R (no commas) and continue to hold the keys till you hear thestart chime 2 times then relesase.Reboot.
Good luck

MacBook won't automatically sleep

My MacBook won't automatically sleep anymore. If I close the lid or command it to sleep, it will. But it will no longer automatically sleep. I've tried tons of fixes and searched for hours on the internet, but still have not found a solution. I seem to have noticed that this starting happening after I installed Windows XP via Bootcamp, so I'm guessing that the problem is related to that. Any ideas?

This is for a Mac that won't sleep.
Here is 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.
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 card.
Also, here is Apple KB article TA2469 about PCI cards and sleep.
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.
Tristan Currier noticed this; "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!"
Allan Jones says "sometimes there is Network activity: launch System Preferences > Energy Saver > "Options" tab and uncheck "Wake for Ethernet network administrator access."
Good Luck!  DALE
