    all of a sudden today my computer shuts off. It's when I leave, I come back and it's off. I have no idea what is wrong and NO clue how to trouble shoot this!

    It's OFF! I tried to wake it up but nothing. I have to go to the button and put back on. It was hot today, but it has been hot the last few days. I have air and a fan. I'm not saying it isn't the heat, just not sure why today of all days.

    It went off late at night as well, when it wasn't warm one bit. it runs just fine as long as there as activity, but about 30-45 minutes of inactivity and it's off.

    What are your power saver settings?

    It really sounds like it is sleeping.

    yeah it could just be hibernating and needs the power button to start back up, or it could be a more serious issue.



    Maybe it is suddenly getting too hot, and as a result shutting itself down before it is destroyed by heat.



    Maybe it's something else. Do you have any new things attached to it? I once had a Maxtor 300GB External hard drive connected to mine, and when I deleted it's syncing software off the mac -- the mac would just shut down on me randomly.


    I pinpointed the cause was the External HDD, it was dismounting itself from finder at random, and when it randomly cuts out like that, the computer crashed. I re-installed the software on the mac, and it worked find afterwards.




    edit: the power button to turn it on, does it reboot completely? Or does it instantly bring you to the login screen which then brings you to the desktop?

    Or does it do the chime, with the grey screen, load, bring up the login screen, and re-load the dock, programs & such?


    The first one indicated it was hibernating, and returned to normal, the second one with the chime and a complete boot means it was actually powered off.

    It's for sure off. When I hit the power button it does the chime, with the grey screen, load, bring up the login screen, and re-load the dock, programs & such.

    I did recently install a time machine scheduler. Although I could not get it to work. I was tired of time machine slowing down my computer.

    Today it shut off as I was working on it. That is awful!

    I will try and unistall the scheduler and see if that is it. Any other help is appreciated!

    Also take a lok at the Console for the logs. Check the entries that are near the time when the mac shut off. Eventually copy and paste them here.

    The Console app is in Applications/Utility.

    help me too please

    This is so long after the last post on this thread but, I was reading this and maybe you can help me with my problem too...my old MAC G4 quicksilver 867mhz just started doing this the other day. i did what you told littleboo to do and the energy saver settings are fine i went into the console and found this the last time it happened...
    2009-07-05 22:03:30.523 HPEventHandler[149]: DebugAssert: Third Party Client: isReady Can't establish connection with the device[/Volumes/Development/HP/Mac-Sirani/mac-software/components/Common/CommonUtils/Sources/CIAUtilities.cpp:82]
    Debugger() was called!

    right before the computer shut down, the startup light on the monitor got brighter and then the screen went black and it shut down. i hooked up a wireless router yesterday and i suppose that could be the problem.
    thanks for any help.

    I think I am going to have to bring it in. It is still happening. I added Ram a few days before this started, not sure if that has something to do with it.

    There should be a panel on the left (if not you can open it with one of the buttons).
    The select "All messages". On the right take a look at the timestamps and try to find the moment when the mac shuts down. You can copy some of the entries before and after that time and paste them here.
    Maybe we will be able to see what is happening.

    I brought it in. Seems that when I put the ram in that I did not close the computer properly. that was, hopefully, it.
