Why is my computer shutting down instead of sleeping?

My comptuer is shutting down instead of sleeping. I have looked at my preferences a million times and nothing has changed regarding my sleep time or any other options.
I looked at another forum answer and tried resetting the SMU by unplugging the cord and holding the power button. That did not solve my problem. What should my next steps be? Should I reset PRAM? Should I suck it up and deal and bring it into a store? I am covered until October.
Please help. Thanks!

My computer shuts down instead of sleeps when battery drains...

Hi there!
So, I just got a new MacBook Pro (the better 15" one) in June. I've noticed, however, that when my battery drains, and the little warning comes up that says "your computer will go to sleep in a few minutes to preserve data," if I let it run all the way out, it doesn't go to sleep but just shuts down. When I reopen my computer after plugging it in, all my stuff is back, but I do have to press the power button and start it up again.
My old computer (White MacBook 2006) always actually went to sleep, and only if I let it sleep for a long time did it shut off.
Have they changed the behavior? Do the laptops only shut down, and no longer sleep when the battery is gone? Or is something wrong with my computer. I'm getting all my data back, and all the windows and stuff are still open, so that's not a problem for me, but if my computer is working incorrectly only three months after buying it, then I'd like to know...
Thanks! Let me know what further information you need to help!

Your computer is not shutting down — it's hibernating, also called "safe sleep". This is indicated by the fact that everything you were working on is undisturbed when you wake it by pressing the power button.
The contents of RAM are written to the hard drive before the machine enters safe sleep, so that if the battery drains completely before you wake it, the contents of RAM (including your unsaved work) won't be completely lost. This is different from ordinary sleep, in which the machine simply suspends all activity without writing anything to disk. If the machine went into ordinary sleep after giving you a low-battery warning and not getting any cooperation from you (i.e. you didn't heed the warning and plug in AC power), and then you didn't wake it for twelve or fifteen hours, the battery might have gone completely dead and your unsaved work would be lost.
In short, yes, this is new behavior compared to several years ago, and from what you tell us, your machine is working exactly as it's supposed to.

Computer shuts down instead of sleeping - Z77A-GD65

Howdy,
Current Build:
MSI Z77A-GD65 Motherboard
Intel i7 3770K CPU
16GB G.SKILL Ripjaws X DDR3-1866
XFX Radeon HD 5770 1GB Graphics Card
120GB Vertex 3 SSD
2 * 1TB HD in Raid0
Running Windows 8 64bit
Problem: I manually select "Sleep" to put the computer to sleep. Computer initially goes to sleep as indicated by the blinking lights on my case. On the third blink, the LED visibly doesn't finish the blink and stays off. Pressing the power button boots the computer as if it was shut down. Windows tell me my computer was shut down improperly.
Random note: Enabling EuP2013 allows the computer to go to sleep properly. If I press a button on my USB keyboard it restarts 3 times before booting. If I press the power button it wakes up properly but with no graphics.
Attempted fixes:
- Got the latest BIOS
- Disabled Wake-Up Events in BIOS
- Changed to OS controlled Wake-Up events
I have not overclocked the system except enabling an XMP profile.

Excellent troubleshooting!

After installing Mac OS 10.5.8 my 2005 iMac G5 shuts down instead of sleeping

After install of OS 10.5.8 my iMac G5 - 2005 model, no Intel processor - whenever I choose sleep from the Apple menu or the time-out goes to sleep mode the computer shuts down instead of sleeping. Any insight would be appreciated.
Thanks.

Try using Disk Utility t repair your disk
   1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
   2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
      Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
   3. Click the First Aid tab.
   4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
   5. Select your Mac OS X volume.
   6. Click Repair. Disk Utility checks and repairs the disk.
Then reboot and repair permissions from your internal drive.

Shuts down instead of sleep

I have tried everything! I have even restored to factory settings and the problem still exists. Instead of going to sleep my computer shuts down. I have checked power options and they look fine however when I change anything in the options it still shuts down instead of sleeps. I am thinking this must be a windows update issue but don't know which one. I have tried everything on every forum I found but no luck. Please help!
TIA

Not sure what to look for with USB software, I haven't really installed
anything that I know of is there a list of this USB online somewhere? The
laptop was new in August 2014, I got the Windows 8.1 update like the other
person did and it took forever. I think he counted 120 software updates. I
did not count them but it sure took a long time. That was about 3 months
later in November. Ever since then I've had the same problem and have tried
different things to circumvent it. It certainly appears to me that the
Lenovo has a severe bug in wakening from hibernate in 8.1 that was not
there in 8.0. And they should fix it. I'm about ready to throw the darn
thing out. Most of the time it doesn't come back from hibernate, you can
hear the fan run when you open the lid but it does not come up. other times
it does nothing until you press and hold down power. I thought HP was bad.
Makes me scream Apple!

MacBook pro shuts down instead of sleeping while connected to power adapter

Hi there,
I am currently facing a rather strange issue. My old MacBook pro (about 2 years old) shuts down instead of sleeping but only when it is connected to the power adapter. I mean it goes to sleep mode perfectly well when it works only with the battery. Is it a know issue ? I'm running 10.5.6 and this problem is quite new to me (happened the first time some weeks ago).
Thank you in advance for your answer.

You might try resetting the SMC and see if this helps:

Macbook shuts down instead of sleeps

I have a 2ghz core duo macbook (modle No. A1181 (EMC 2092)) that I recently restored from a time machine backup. It was at 10.5.5 and now its at 10.6.8. So, right now I close the lid of the macbook and immediatly shuts down instead of sleeping. The previous macbook (the one I made the back up from) didn't have this problem and nor did this one before the upgrade. I have already tried resetting the smc and the pram. Anyone have any ideas?

Having never shutdown my laptop, I was guessing on its reaction to closing the lid. So, I shutdown my MBP and closed the lid. It did continue the shutdown, so there seems to be a problem with yours.
Sometimes, sleep and shutdown issues can be solved by resetting the SMC

Computer shuts down instead of going to sleep (no battery)

Hi, I've checked some of the posts and notice that there are power management issues to these macs. I just picked up a used one and with no battery installed, if I go to Apple-sleep, the coomputer will shut off instead of sleeping. If in the energy settings, the computer is set to sleep at a given time, the computer will do a hard shutdown. I have it set to never sleep for now, but would like some guidance from the forum on how to deal with this power issue.
any ideas, thanks
Lisa

I've been having this problem for the last 4 months. I called Apple today and let them know about my MacBook which is only 1 year old. I've installed the battery update, reset the SMC and calibrated the battery, yet always when I reach about 45% my MacBook shuts down; I've never once ever had a low level warning.
Well, Apple asked for the serial # on the battery and then they told me that that serial # was not affected and that the Battery Update program is only for Apple Care customers. I told them their web site says nothing to the effect - they said regardless that I'll have to buy a new battery and I could not be helped; I'm not sure who to complain to since from what I have read, the problems I've had with my battery and the time period I bought the MacBook (directly from Apple) all point to the battery issue. I need someone to give some advice on who to call.
Here is the site i went to and the phone number I called is from there:

I have a macbook air from mid 2012. After installing the MacBook Air Flash Storage Firmware Update 1.1 my computer shuts down instead of restarting. Does my macbook need a replacement drive?

Anyone experience the same result after installing MacBook Air Flash Storage Firmware Update 1.1? Why did my macbook shut down?

IMac shuts down instead of sleeping

Hi everybody. Forum newbie here. I'm having a bit of trouble with my iMac. First of all, it's a G5 with 2.0 GB of facory installed RAM, and running OSX 10.4. I bought it barely used from a friend and when I first got it in the spring it shut down instead of going to sleep a couple of times. It wasn't a big deal, since it was overnight and not in use at the time. From then on it was fine. Over the past few days however, it has started doing this again, and much more aggressively.
It seems that it doesn't go to sleep at all anymore. It just shuts down. If you put it to sleep it will shut down. If it goes to sleep on its own, it shuts down. I went into the preferences panel and set it so it never goes to sleep and the monitor shuts down after 2 hours. I left it and went back to it after about 20 minutes and it had shut down. This happened repeatedly last night, causing me to waste 6 or 7 DVD-R, as I was attempting to burn one and it would shut down during the burning process. I had a pretty bad case of computer-induced Tourrette's syndrome I've gotta say.
As long as it's in use, there's no problem, but if you leave it alone for any length of time over say 20 minutes it seems that it's going to shut down regardless of your energy saving settings. And it doesn't seem to sleep at all anymore.
I do lots of video work and between burning DVDs and rendering video, I frequently need to leave the computer alone and let it do its thing. If it's going to shut down every time I leave it alone, then that makes my work impossible, or at least extremely annoying as I will have to run back and forth every 10 minutes to jiggle the mouse to make sure it doesn't go to sleep.
Anyone know what might be causing this or how to fix it? Thanks so much!

Welcome to Discussions. Which model do you have? If it's a Rev A (not ambient light and no iSight), then you might qualify for the Repair Extension Program. In any case, try and reset your PMU/SMU. PLease post back,

Shutting down instead of sleeping..

For some reason, my Mac keeps shutting down instead of going to sleep. I've checked all the settings and nothing I can find is set to shut down. Any idea what is going on? Possibly related... my Dashboard stuff keeps disappearing (see post in Finder,Dock discussions) Hope someone can help!

Any time you have problems with power management or sleep/wake or shutdown/boot there are a few basic steps to try. These apply both to Tiger (10.4.x) and Leopard (10.5.x) versions of the Mac OS.
First, reset the low level controller in your computer that handles power management and sleep/wake functions (including scheduled events). In an intel-based Mac that is the SMC. In a powePC-based Mac that is the PMU. To do this, go to the main Support page here and search for "reset SMC" or "reset PMU" as is appropriate in the search field at the top LEFT of that page. In the list of Knowledge Base articles returned, find the instructions specific to your model of Mac. It is not tough to do, but you do have to find the instructions for your specific Mac. Note that resetting a PMU may require you to manually adjust the date and time (System Preferences / Date & Time) the next time you log in.
Next, reset the Parameter memory (PRAM). PRAM holds copies of various system settings for rapid access and if it gets out of whack all sorts of odd things can happen. The instructions for resetting PRAM are the same for all Macs. Shut Down the computer. Locate the 4 keys Apple-Option-P-R. Press and hold those 4 keys, and while doing so, press and release the power button. Keep those 4 keys held down until you hear the SECOND startup chime, then release them. Your computer will continue to boot up normally.
Finally, perform a Safe Mode boot. A Safe Mode boot does some maintenance tasks in the background such as repairing critical system file permissions and deleting some cache files, etc. To do a Safe Mode boot, hold the "shift" key while booting until you see the spinning gear on the gray Apple screen. Be patient, this will take a while. Eventually you will get to a log in window that includes a notation that you are booted in Safe Mode. No need to log in as the maintenance stuff has already happened. So just Shut Down from there and reboot normally.
If your Sleep problem persists after these three steps, take a look in the Console to see if any helpful error messages are being thrown (Applications / Utilities / Console -- select "All Messages" in the column on the left). Now even during a NORMAL boot and log in, there are a lot of Console messages generated, some of which can look pretty scary if you are not used to them. But a normal Sleep or Shut Down should generate very few messages, so scroll back in the list to the time where you tried to put the computer to Sleep and see what you find.

MBP unib. 17" shut down instead of sleeping (also when plugging magsafe)

Hi All!
I've this problem.
When i get the system message that the battery is running out and i wait for it to discharge sometimes the MPB just shut down without apparently sleep, but when i turn it on the screen shows it went in hibernation.
Other times it goes and still in safe sleep but when i plug the magsafe it shut down immediately and i have to reboot it from hibernation every time.
Is there any way to fix this myself or i have to send it to support?

Calibrate your battery and see whether that makes a difference:
http://support.apple.com/kb/HT1490
I tried but apparently nothing happened.
the calibration steps are:
_Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged._
_Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in._
_Disconnect the power adapter while the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, the low battery warning dialog appears on the screen._
_At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep._
*At this point my macbook saves ram on disk for hibernation and shuts down itself imediatly after. Or in best cases it stays in a "can't wake" sleep for an hour or two and if i plug magsafe while in this state it shuts down...*
*Anyway i also did the last 2 steps:*
_Turn off the computer or allow it to sleep for five hours or more._
_Connect the power adapter and leave it connected until the battery is fully charged again._
And again, when i leave the mac on battery power after the warning dialog the insane behavior occurs every time.
Can't figure out why my battery seems not to handle the 5 hour forced sleep it should.

IBook Shut Down instead of Sleep, is that a problem?

Hi,
My ibook used to go to sleep when batt runs out, but recently, it shut down. is that a problem?
Thanks

welcome to the discussions, It sounds like your battery is running all the way down and causing your machine to power clear down instead of sleeping.

My Power Mac G4 shut down instead of sleeping

Is there anyone out there having this problem..?
When I put my PM to sleep it shut down instead. If I try to restart it right away it starts booting but fails after a couple of seconds and shut down again. If I wait for a longer while it starts like it should!?
I have tried to replace the backup battery with no luck.
Power Mac G4 "Quicksilver" Mac OS X (10.4.8)

Hi! - I had a similar problem with my G4 which I bought second hand. It would sleep and then when I tried to awaken it - it would then shut down. Long story short - it had a third party Airport card which I removed as I did not need it - problem solved! Seemingly third party bits and pieces can sometimes cause this problem.
Hope this helps.

IMac G5 shuts down instead of sleeping

Just recently (after install of 10.4.9 and latest security update), computer shuts down when I try to "sleep" it. This occurs from the "Apple Menu", the "Welcome Screen" and the power button (when assigned this function from the preferences). This problem originally started as rebooting when trying to "sleep" it.
It also has the annoying condition that when powering it up after an "uncommanded" shutdown (or any shutdown for that matter), it has dropped the connection to my router as if the ethernet card(?) is no longer operational. However, restarting from my account usually reconnects to the router.
I have tried the following;
1. Repairing permissions, disconnecting everything from the computer, and waiting a minute or two before rebooting.
2. The above procedure including repairing permissions after reboot and before trying to sleep it.
None of this has helped.
Other than this the computer seems to be operating normally.
But I would like to be able to put it to sleep rather than let it run all the time or go thru the process of restaring after powering up to regain my internet connection.
Any suggestions/recommendations?
iMac G5 17" 1.8ghz Mac OS X (10.4.9)

Thanks for the response. I checked my serial number and it does fall within the range for the repair extension. However, it is not exhibiting the symptoms ( no video, no power and scrambled or distorted video) for which the repair is authorized.
On the other hand, I have discovered that the computer is treating the sleep command ( no matter how it is initiated) as a power failure. I know this because if the check box "Restart after power failure" is checked it restarts after the sleep command ( I set it up to sleep after 5 minutes of inactivity with the box checked. At the set time it acted as if it would go to sleep but restarted. Several cycles in a row ). If it is unchecked it simply shuts down. Interesting.
It looks like a call to Apple is next.

Why is my computer shutting down instead of sleeping?
