    Moments ago, I was sitting in my room and while my 27 inch iMac was in sleep mode, it just turned on by itself (screen stayed off), but I heard the fans, hdd, and disc drive turning on and 5 seconds later, it put itself back into sleep mode...lol really creepy.

    Also, there's been several times where I would be asleep and it would turn itself on in the morning. Since I have the time announced every hour, I was suddenly woken up by the sound of the time.

    It's not something I care enough about getting it replaced, kinda think it's funny in a way, but I would like it to stop, or at least know if anyone else has this problem?

    Try looking at the reports in Console if you are curious about what it is doing.

    I just checked the console and it seems like 1Password is the problem. I uninstalled it a while ago and thought it was gone, but saw that it was still running when I checked my "Activity Monitor." I proceeded to find the process in my library and deleted it and it seems like it's still on my system? Not sure. I still notice it come on every few days, maybe every day, but I just don't notice since it's only on for about 10 seconds and the screen is off.

    Here's the console message (I believe I was not on the computer during those hours):

    Nothing to be concerned about citizen - - just a quick government security scan - - go back to sleep.

    Sounds like the wake on demand feature that apple added to snow leopard. You mac will turn on (screen off) for a few seconds while it updates the airport base station sleep proxy service then it goes back to sleep.

    It adds an entry to system.log when it does this. Can't remember what entry is called as I don't have it enabled at the moment. Click on Show Log List in console and select system.log and have a look for something like System Wake.

    That's is walk on demand, is really easy to disable it:

    Go to Preferences

    Click in Energy Saver and untick the "Wake on.." feature
