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 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 Pro NOT sleeping properly anymore, and getting hot.

My MacBook Pro does not sleep properly anymore, and gets really really hot, anytime I send it to sleep either by closing it or by selecting "sleep" from the menu. It also loses all its battery really fast while on this state (even faster than while being awake and being heavily used).
It started a while ago only, or at least it was not there from the begining. I had never before had to put off a MacBook Pro, except while flying... I always just close them and they sleep after a few seconds; BUT I can not do like that anymore with my new MacBook Pro... I have to save, close and shut down... then turn on, open my apps, and open my files... its not something to be happy of... I'm very sad with this problem and I have been unable to find the reason for the sudden change.
Please I need help with this.

An additional detail I forgot to mention:
Everytime I tell my MBP to sleep, or just close it, the computer does not seem to go off (because of the levels of the sound of the HD and of the fan), though the screen goes off correctly.
Now, the strange part is that everytime I "wake it", the screen goes on immediately, asking for my password, and after inputing it correctly the screen goes COMPLETELY OFF for 2 seconds, before "coming back normally".

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.

My PowerBook Won't sleep properly

Hi all,
Quick question - my laptop doenst sleep properly when you close the lid - the light doenst 'breathe', and the computer stays hot like it has been running. The battery is always empty when i come back to use it. I have seen on the forum that this is happening a bit... any sugestions????
Thanks

I don't know if you saw the very long discussion of this topic here. I have been following this for a long time as my MacBookPro has had the same problem off and on since I got it last September. Near the end of the topic is this message that says that you may have a hardware malfunction that Apple will fix:
http://discussions.apple.com/message.jspa?messageID=4082285&tstart=0
I would suggest taking it to your local Apple repair shop.

Macbook won't boot properly.

Macbook won't boot. When turned on, it starts clicking; after a while, I get a gray screen with a blinking folder in the middle that has a question mark on it. After a minute or two, it shuts off.

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
Put your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option Key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
Or if you are running 10.7 Lion, boot from the recovery partition (Command +R on boot) and use Disk Utility to repair your OS 10.7 partition.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is, then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

MacBook Pro won't sleep properly when Aperture 1.1.2 is running.

I was working on photos in the airport. I closed the lid of my MacBook Pro, put it in my awesome BrainCell from Tom Bihn, got on the plane, and when I took out the MacBook after we passed 10,000 ft - my machine had crashed. It was insanely hot - like, too hot to literally handle. I booted it, and it reported kernel panic. I see the same behavior if I put the MacBook to sleep explicitly (which it appears to do) and Aperture is running. Crash, unless I'm plugged in and constantly giving it power.
My MacBook does not do this when apps like Firefox are running. This is very bad - it has caused corruption in one of my libraries already. Aside from always quitting Aperture before going to sleep, does anyone know of a fix for this?

Sleep/wake issues have haunted every powerbook I've owned, from the 3400 to the Lombard to my PB G4. I use a Kyocera KPC650 with my G4 PB, and the rule of thumb is it's necessary to kill the connection and remove the EVDO card BEFORE attempting to put the PowerBook to sleep. Just a bad idea to risk it.
I've had problems with USB dongles, hubs, etc. and after years of trying to resolve the source of sleep/wake issues, the general rule of thumb for ALL Mac PB/MBP is to remove peripheral devices before attempting sleep, or at least NEVER change what's inserted into the computer while it IS asleep (USB peripherals, drives, etc, but this even includes power adapters). A general observation is that the computer freaks out if status of peripherals is changed while asleep, and it wakes up to a different condition set than when it went to sleep. In most cases, resolution requires a hard reboot/re-start (sometimes this can be avoided by closing the lid, and trying to get the computer to re-engage sleep, then trying to wake it again).
In some cases, I suspect too many peripheral devices places a burden on the power supply, and the computer can't supply enough juice to power up the devices under the load.
So some problems stem from hardware issues, and some from software problems. Best answer is to not even try, as there's too many variables (e.g. right-sided USB ports behave differently than left-sided ports, etc).

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:

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
