iMac turns on alone!

[cacafuegos]

Hello,

I am new to this forum and I am new to the Apple world, bought an iMac 2,4 a month ago and I am more than happy with it.

Most of the little issues that came up in the first weeks of operation I have resolved, often reading useful threads in these forums.

My problem now is that my iMac turns on alone, from time to time, although I have not scheduled it to do so in the "energy saver". I normally turn it off at the end of the day, I mean off not sleep mode, but sometimes I wake up in the morning to find it already waiting for me in the user log-in screen. As far as I am aware, there is no software that I have installed and requires it to switch on (I understand the time machine does not do that).

Any ideas?
Thanx a lot,
T.O.

I don't know what to suggest, but switching off the plug/socket will help. There's software which does it I just can't think of the name, sorry.:(

Always worth resetting the PRAM (http://docs.info.apple.com/article.html?artnum=2238). Hold Command, Option, P, and R on boot.

Yeah, I'd though along those lines but I'm getting confused (having just gotten off the phone to Apple talking about DFU). :D
Hope you get it fixed-a-mondo.

goto system preferences-->energy saver-->options

Check boxes that says restart after a power failure.

Go back to sleep tab and click on schedule.

See if it is set to start up at any time?

He already set it wasn't set in the Energy Saver settings :rolleyes:

Have you fixed this, OP?

thank you all for your answers!

I did reset the PRAM yesterday and it seems that the problem is resolved, so far. I will wait a few days to make sure, but maybe this was it.

all best,

This is also happening to me, too.
I just recent got a new 20” imac from work and everything about it is great.
It only happens once in a while when I would come in and the computer would be on. I always shut my computer down when I leave.
A slight annoyance.

that happened to my bros and it freaked meh out

hello,

this morning my iMac was on again...I think I will consider disconnecting it from electricity every time I shut it down...

what a strange issue, isn't it?
cheers,

You should just return it :)

Do you have EyeTV? I had the same problem, it was a setting in EyeTV Prefs where by it checks the servers to see if you've remote scheduled anything... this causes it to switch the computer on...

Hope that helps. :)

If you are using the wireless mouse and/or keyboard, the bluetooth Advanced settings include a checkbox for "allow bluetooth to wake this computer". I found that if it got windy outside or the nearby army base was practicing night maneuvers It would jiggle my bluetooth mouse enough to turn on the iMac.

Hope that helps.

In my case, it was also Eye TV waking up the computer to update the program guide. I set it to manually update and problem fixed.

hmmm...no bluetooth, no eyetv...
thank you,
