  • 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.

  • 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.

  • G5 iMac sometimes shuts down instead of sleeping

    I’ve recently started having a problem with my G5 iMac whereby it shuts down by itself after a while instead of sleeping.
    Basically, I start up a task that might take awhile, such as burning photos to a DVD for backups, or updating an Aperture vault, and I go away for a while. I come back later, and sometimes I find that my iMac is sleeping as expected, and other times I find that it has shut itself down. It appears to complete the task before it shuts down. I’ve checked all of the preferences and can’t find any that tell it to shut down.
    I’ve also checked the lists of G5 iMac that are affected by the known power supply capacitor issue, but mine is not in the list of affected units
    I’ve searched the forums here, and I haven’t seen any other reports of this happening to anybody else.
    Any ideas on what is happening?
    PS: I’ve also been having occasional issues with unmounting external WD (Western Digital) FW drives lately too. I dismount the drive from the desktop, and the icon disappears as normal. I then power the drive down, but sometimes it will warn me that the drive was improperly removed and that data could be lost. This is odd since the drive icon was no longer on the desktop, so the drive appeared to be dismounted. This has happened with several different WD FW drives. The only thing I’ve noticed is that this doesn’t happen if the external drive appears to go to sleep after dismount. Sometimes, the drive appears to be active (even though the icon has disappeared). Again, any ideas?
    Thanks in advance for your help.

    Not before a normal shutdown. And since I'm never around when it shuts down by itself, I can't say for now.

    I think I have around 165 GB or so of free space on the internal drive, so that should be OK. I didn't know about the thermal paste.

    I'm trying to keep my backups up to date, and I figured that it may need to go in. At some point, I would like to get a new computer, either a new 24" iMac, or a Mac Pro with a 30" monitor. I was hoping to get the new one before I'd need to send this one in for repair, but I might not be able to wait. This iMac is about 3.5 years old, so my Apple Care has expired.
    It is odd that it always seems to complete the task at hand before the shutdown. If it was purely due to hardware, it should be more random than that, and not wait for the task to complete. I was starting to wonder if there is some sort of bug in the latest version of Leopard. I didn't have this happen before I upgraded to 10.5.6, but maybe that just a coincidence.
    Thanks again for you help.

  • IMac keeps shutting down while in sleep

    I have an iMac G-5 without iSight.......not sure if this started happening after the last sucurity update or installing HP printer software, but now when the computer goes into sleep, it waits awhile and then shuts down entirely, forcing me to turn the computer back on. I uninstalled the HP software, and repaired permissions, but this still keeps happening. Any ideas on what caused this and what I can do to fix it?
    iMac G-5   Mac OS X (10.3.9)   80 gig hardrive which has about 2 gigs left

    Hi,
    I am having a similar problem. I have an iMAC (serial in the range W8435xxxxxx - W8522xxxxxx) and in the two weeks, when the computer is put to sleep it turns off. However, I only notice this in the morning after it has been asleep all night. The problem seems to be far more frequent when I put it to sleep as opposed to just letting it time out and go to sleep that way.
    I have applied all updates and the only modification to the computer is extra ram (from Other World Computing).
    I have seen elsewhere that I can see the computer's reason for shutdown in "system.log". Can anyone tell me how to find that so I can look for the shutdown code there?
    Any ideas?

  • 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!

  • When I click sleep, Imac turns off not just sleep

    When I click sleep, Imac turns off not just sleep. Any fix?

    Hi Hank,
    Some things to try...
    Have you done a PRAM reset, CMD+Option+p+r...

    In fact, do 3 in a row, takes a bit of time.
    Intel-based Macs: Resetting the System Management Controller (SMC)...
    http://support.apple.com/kb/HT3964
    (SMC reset=  Shut down, disconnect power cord for 10 seconds, reconnect power cord, wait 5 more seconds, turn computer back on)
    but it is slightly different:   (PMU REST = Shut computer down, disconnect power cord for 10+ seconds, reconnect power cord WHILE SIMULTANEOOUSLY PRESSING POWER BUTTON, let off power button for a few seconds, then press power button again to restart the mac mini.)
    Can also be caused by USB or Firewire devices.

  • IMac is shutting down when it attempts to sleep with 'hibernate image' error

    Our iMac is shutting down when it attempts to sleep.  This started following a Yosemite security update, though of course it is difficult to determine for sure that that was the cause.
    In the console, the following message occurs before every shut down:
    kernel[0]: Failed to get hibernate image filename
    Suggestions?  Does someone perhaps know what exactly the hibernate image is (we have a tiled screensaver that shows an iPhoto album -- could it be that one of those files is corrupt?) so that I can attempt to change it to see if that fixes the problem?
    Thanks!
    System:  iMac  (21.5-inch, Mid 2011), OS X 10.10.2
    Already tried:
    I reset the SMC by following Apple's instructions for this computer (turn off, unplug, wait, replug, wait, turn on)

    More information:
    1. It looks like the crash/shut down is happening when the display tries to sleep (timing is 15 min after the beginning of automatic sleep).
    2. When sleep is first initiated, I am seeing this in the console (not normal?):

  • AirPort Extreme powers down when iMac is shut down

    9-month old AirPort Extreme, with two hardwire connections: one to the DSL modem, and one to an iMac. After months of perfect performance and reliability, the AirPort extreme now completely powers down as soon as the iMac is shut down or goes to sleep. It powers back up with the iMac. Logging out the iMac to another user account does not shut down the AE.
    Naturally, we checked the electrical supply for all three devices and they are all plugged into a perfectly ordinary surge supressor strip.
    We're thinking the AE has a hardware failure...but what kind of bizarre symptom is this that it shuts down when it loses signal from it's only Ethernet client?

    This is certainly odd. Have you tried a different port on the AEX?
    It may be best to contact Apple about a warranty exchange.

  • 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,
