I think my iMac is haunted!

[tombarnes]

My iMac keeps turning itself on when it has been totally shut down. And it scares the c&*p out of me with the startup sound when im just drifting off to sleep!

How can i stop it? I have tried System Preferences> Energy Saver> Schedule.

There were no scheduled start-ups.

I am used to having my mac on during the night, as I sometimes schedule EyeTV to record TV Shows, but I don't have any scheduled when it still turns itself on. I have had EyeTV for around 18 months, and only in the last couple of weeks has my computer started to boot up.

Many thanks,

Tom

you've tried reseting the PMU and such, i presume?

do you see a pattern on when does this happen?

uncheck the restart automatically after power failure too... i know theres probably no power failure, but just in case..

Excuse my ignorance, but what is PMU?

Haunted iMac... whoops I couldn't find the ghost story here. Sorry!

Please note, the firmware IS up-to-date.

I'm not in front of my Mac right now... but I think in the advanced energy prefs, there is something about allowing network devices to start the computer... go look for that and make sure it's not checked?

Otherwise, assuming that this guy is under warranty still, make Apple deal with it.

HELP!

Why is my fan so noisy now I have reset the SMU/PMU???

How can I resolve this?

I have tried the hardware test (pressing D on startup).

HELP!
