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.

  • 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.

  • 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.
    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.

  • 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:

    Good luck!

  • 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.

  • 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!

  • 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 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 G5 Power mac keep shutting down

    Hi,
    All of a sudden My mac keeps shutting down, I have installed nothing recently no changes nothing for months
    and all of a sudden it keeps shutting down.
    Check the hard disk using disk utility and it says it appears to be okay
    CPUs running at 60 to 62 degrees
    please help
    John

    I believe -122 is a power issue...
    Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange problems...
    See which one your G5 has...

  • 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:

  • 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.

  • 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,

  • 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.

  • Power Mac G4 Shuts down at start up

    Hello,
    I have a power mac g4 that Shuts down at start up. It will get to the white screen with the apple for about a minute and then shut itself down. I tried starting up from a disk and it doesn't even get that far.I haven't replaced any parts yet but I was wondering if it may be a problem with the computer's power supply. Any suggestions are appreciated, Thanks

    You may need to reset the logic board. If you open the side of the G4, you should be able to find the reset switch.
    Unplugging it first would be a good idea.
