My Mac mini shuts down instead of sleeping.

I've been leaving my brand-new Mac mini on, assuming it would go to sleep like my macBook or dear, departed iMac would.  I'm running OS 10.8.4, and I have the Energy Saver settings so the display goes to sleep after 15 minutes and the CPU sleeps after 1 hour.  Instead, I return to find it shut down, hard: no white LED (blinking or steady), it won't respond to keyboard, mouse clicks, or even the power button.  The only way I can get it back is to unplug the power cord, then do a full-up start.  I have a Belkin powered USB hub attached and a Firewire external HD for Time Machine.
I need to know before the warranty expires--is this a hardware issue? 
I'll be really upset if all the migration and setup I just did was a waste of time because of a hardware defect.  I ultimately plan on making this a home theater PC, and if I can't rely on it to stay turned on, it'll be useless to me.

1. Reset the SMC, as per > Resetting the System Management Controller
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.
2. Click Schedule.. on the Energy Saver pane and make sure that you haven't accidently set it to Shut down at a given time.

  • 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.

  • Mac Pro shuts down instead of sleeps.

    I run a  2008 Mac with OSX10.5.8, with 2GB memory and 2x2.8Ghz Quad core processors
    It works great! however recently it has started acting strangely. What i mean is it normally goes into sleep mode after 15 mins of inactivity or so.
    However recently it sometimes seems to shut down after a period of inactivity .... Is there a setting which has somehow been  changed or is it the signs of a more serious issue?
    Any help appreciated!

    Hopefully post stll being checked. I have just started to have the same issue with my Mac Pro 2008. It seems to be shutting down and starting fine but the last few times I put it to Sleep, it will eventully shut down on its own. Restarts fine with no message of on screen of improper shut down. I have: reset SMC, zapped Pram, checked Console. Will run Disk Utility this afternoon.
    I can put it to Sleep and Wake it again with no problem. However, it seems after a longer time in Sleep mode is when I may have a problem
    I shut down last night at 6 PM. When I Rebooted this morning (it had shut down) I can see Console notes a  Sleep failure code and Improper shutdown detected but this is noted this morning when I am rebooting it.

  • 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.

    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.

  • 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.

  • Mac mini shut down on its own, will not restart, grey screen, spinning wheel. Unplugged everything, will still not restart. Did safe boot, will not restart after safe boot, only grey screen with spinning wheel.

    Mac mini shut down on its own. Could not restart, chime, grey screen and spinning wheel. Unplugged everything but monitor, still only chime, grey screen and spinning wheel. Started in safe boot, shut Down, will not restart.
    This happened a couple of months ago, unplugged everything and it restarted, now that won't work.

    Hi BDAqua,
    I just did the repair as you suggested. T ran the disc repair, and twice it cam back, the volume macintosh seems ti be okay, I also ran the verify and permissions repair, both came back okay.
    I was actually hoping that they would find something, so they could repair. I shut the computer down, and restated with out holding a key, and I started up great. I'm baffled.  I have moved 20 GB to an external hard drive, as I only had 10% open space.
    I have Tech Tool 6, would you recommend to run a repair check on that, or just leave well enough alone.
    I agree with you on the new Mac's, I have problems with no disc for back up, until they realize their mistake I will stay with Snow a Leopard. This is the first problem I have experienced, so I can't complain. Their last programs are not as perfected as under Steve, prior to his handling over the reins, hope this is not going to be the future we can expect from Apple.
    I will wait to here back as to your suggestion regarding the Tech Tool check
    Thanks for all your help.
    Gratefully,
    Cheri

  • 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!

  • 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:

  • 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!

  • Mac mini shuts down after 10 seconds..

    At first today, the CDs and discs kept automatically ejecting and wouldn't read (obviously). So I keep putting them back in hoping it would read or hold something. Then I restarted and the Mac Mini shuts down after 10 seconds of the seeing the desktop. Did I fry it? I did hear a weird sizzling when I put my hand on top of the mini. And is this under any warranty - I bought it Feb. 07? Any help would be greatly appreciated.

    Any thoughts on that?
    One or two come to mind, not least that if the unit is under warranty now (as it clearly is) and they aren't taking this fault seriously, then buying AppleCare so it remains under warranty longer isn't the right solution - having them examine it and resolve the problem is.
    There's no doubt at all that in the event there is a system with a suspected fault, extending the warranty long enough that the system ceases to function and can be repaired is a good thing, but it shouldn't be necessary to go to that extreme in order to get a problem resolved now!
    I would simply take this elsewhere and have it looked at. While odd noises are sometimes hard to hear in an environment where there are people and other activities going on, and thus it is reasonable to expect diagnosis of them to prove difficult, a system that shuts down of its own accord after a few seconds is clearly not working correctly. To be sure, if it is overheating, then testing it when it's cold is likely to miss the problem, but the description of the fault from the user ought to give enough clues to put the system on test long enough to see what happens when it warms up. If the fault can't then be replicated with a system that is at normal running temperature and under load, then giving it a clean bill of health is reasonable.
    Thus, in your place I would ask them if they did, in fact, test it in that way. Alternatively, write a description of the fault, specifically identifying the premature shutdowns and the circumstances in which they happen (if they still do) and the noises and the circumstances in which they occur (if they still do) and take the system and description to an approved service provider and let them look at it.
    If the shutdowns are no longer occurring, and the noise is absent, then whether you buy AppleCare or not is really a matter of how confident you are that the problem has gone. If you have doubts that the system is running correctly, AppleCare is expensive but at least extends the warranty sufficiently that you can stop worrying too much. Alternatively, if the problem(s) still persist, rather than AppleCare, have the system examined and repaired right now.

  • 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

  • MY mac mini shut down unexpectedly and now it won't restart properly

    My mac mini shut down unexpectedly.  When I restarted it the screen turns blue and a box pops up that advises "Finder quit unexpectedly".  It gives me an option to ignore, Report, or Reopen.  The cursor works, but none of those button work.  I'm stuck on this screen.  I tried all the support suggestions with no luck.  What else can I do?

    The "worm" as you call it is usually referred to as a Thermometer progress bar. It is showing that your Hard Drive cannot be mounted, and a Disk Utility (Repair Disk) is taking place. If not successful, your Mac will shut down, since it cannot be started up successfully.
    You have unresolved Damage to the Disk Directory.
    If you do not have Backups, making them should be Top Priority.
    Otherwise, boot your Mac from an alternate Boot Drive. If you do not already have one, buy a drive to replace the Internal Drive currently inside your Mac, and an External enclosure to run it in. Install Mac OS X on it and boot your Mac from the fresh Install.
    Then you can attempt to repair or salvage from the old drive at your leisure, using the full power of Mac OS X to do so. When your situation is stable, swap the Internal and External drives.

  • 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,

  • Mac wont shut down, restart or sleep - corrupted software update?

    My Mac Pro (2007 - OSX 10.6.7) will no longer shut down, restart or sleep. When I try to shut down, it logs me out of my user account, shows the light blue screen, momentarily shows the Leopard space background screen, before showing the blue screen again, and finally returning to the login screen prompting for my user/password.
    The only way to poweroff from this point is to hold down the power switch until it forces a power down. This issue has been present for the last two weeks or so ever since I did a Software Update containing a security update. Initially it just failed to perform that update, although after a few days it did do the update, seemingly by fluke. After that, the problem persisted and now there is a new update (Fonts) which again fails to update.
    I have tried all of the following:
    Power off Mac, unplug power and leave for a few seconds
    Power on Mac holding down Ctr + Opt + R + P (resetting PRAM etc)
    Boot up from install CD and perform Disk repair (it did find problems with the disk and repaired them)
    Check and repair permissions
    Delete Software Update related plists & caches from ~/Library and /Library
    Still the problem persists. Examining the logs shows me this:

    I can paste the crash report referred to in the logs if that would be helpful but for now will leave it out as it's huge and largely full of gobledygook.
    I'm at my wits end now. I've always been very proud that in ~4 years of Mac ownership I've never had to reinstall OSX - something I used to do on an anual basis with Windows. My next step probably is a full reinstall, but I really do consider it a drastic step and a last resort.
    Here's hoping that the Mac Support Community can help me out
    Thanks in advance.

    As a followup, upon the advice from someone else I created another user account (non admin) and logged in as that user. From that account I could successfully power down.
    I'm still convinced the issue is related to Software Update as examining the logs showed none of the Software Update related entries as above:
