Along with the magic of my iMac staying awake during a 10 second power outtage... I've found another strange Mac power.

Even though the power scheduler isn't in use my iMac always turns itself back on at either 5 minutes past every hour, or an hour after it's been off (haven't experimented with it yet). It's a little annoying. I was dozing off to sleep and DUUUUUN - it woke me up!

Could there be anything telling my machine to automatically turn itself on?

Is there PRAM on this model? Is there any way to reset any setting on the Motherboard? Alternatively, unplug the mac when you sleep!

I think I'm going to have to! I mean I went to a lecture this morning, iPod had charged up overnight so I turn off... come back and the little white "monitor is off" light was on!

I'm scared to unplug it just incase it still came on. Then I'd probably cry.
 
I seem to recall that with OS9, you had to set the Power Management (startup/shutdown/sleep) thingy whether you intended to use it or not. Even if the extension wasn't active, it would still execute whatever settings were in there.

What you might do is go into Energy Saver in OSX, and click "Restore Defaults." After that, restart the machine. Then go back into Energy Saver and put the settings where you want them. It's worth a shot.
 
Ruddy nora! I downloaded the new security update, restarted. alls well. I turn off the "restart after power failure" option in the energy settings and shut down the iMac.

Go out for an hour. Come home and it's ON. I tried the above schedule options too, even setting it for a time the iMac is always on at. I don't understand this at all! How long does my Apple phone support last for now?

Is it possible there was a surge of excessive power that cause this power outage, thus somehow keeping your Mac on for 10 seconds (which it really shouldn't do) and also frying something in the process? You have this thing on a surge protector right?

No, just plugged straight into a regular ol' power socket.
 
I'm getting a feeling this is hard to believe ;)
Going to film this happening later. Just got to work out what the pattern is. Seems to be 5 minutes past every hour.

OH! and it only happens if you shut the machine down in OSX. If I was using Windows last then it's fine.

The same thing happened to me when I had my my iMac. :confused:

THANK YOU. It isn't just my crazy electricity then. I'm going to ask if the Genius Bar folk if this auto-wake up could be caused by anything.
