    iMac display will turn off, but won't go to sleep...
    Hi everyone!

    I've got a problem. I want my Mac to stay on for a certain amount of time (display off) before it goes to sleep.
    The thing is, whenever I do this (system pref.), the display will turn off after the time specified, but it will never go to sleep...
    Does anyone know why it does that? Any help would be greatly appreciated!!!

    Cheers, Anthony

    Mac OS X 10.5.8

    I've tried everything, at the moment it's just on the default settings.

    Thanks for the reply!

    Do you have any applications running that would prevent it from going to sleep?

    Not that I know of. I tried quitting all applications and then doing it, still won't go to sleep.

    Try telling it a bunch of lame jokes. It should go to sleep then.

    A few suggestions:

    Videos - Free video downloads and streaming video - CNET TV

    It talks about notebooks but some info relates to imacs too.

    It's a dumb question, but how do you know it isn't going to sleep? With the monitor dark, and with no other lights on it, how do you know it's still working on something? My iMac is set for the default, and it dutifully goes dark on schedule. In the mornings, when I touch the keyboard, it wakes up and the screen comes back, just as advertised. But I can't think of how to know if it was secretly still awake in the dark...

    This sometimes happens with me if an application is still running on something. One thing to do - quit all your apps before sending to sleep and see what happens. If that doesn't work... beats me!

    One curious thing - I discovered that Time Machine still backs up when the iMac is asleep. Odd - so I'm starting to shut down completely instead of sending to sleep.

    Not so dumb...that's the question and answer I've been wanting to see.

    And Time Machine has never backed up either one of my Macs while they were asleep.
    I cannot be held responsible for the things that come out of my mouth.
    In the Windows world, most everything folks don't understand is called a virus.

    I thnk that when it is really asleep you have to press the power button to wake it up.

    I have mine set so the screen goes black after 15 minutes and set to go to sleep after 1 hour. If I move the mouse within that hour the screen will come "alive" After that hour I cant simply move the mouse too make the screen come alive, I have to press the power button.

    I also had set the timer to put the machine to sleep at 1 am (it reminds me I'm up to late) and set it to "wake up" about the time I normally would.

    About a week ago I downloaded an alarm app that goes off in the morning. I keep the itunes remote control next to the bed and it works as as a snooze button.
