Mac turning on by itself?
« on: August 19, 2019, 03:34:08 PM »
I noticed that my 9600 mysteriously was booted yesterday, so I turned it off. I went to sleep, then woke up to it on again. I came into the studio and shut it down, but as soon as I did it... turned on again. The Shut Down command is now functioning as a reboot command. It refuses to turn off. Why is this?

That used to happen constantly with my 8100 and it drove me nuts!! It would turn on every night and I would turn it off, then 30mins later it would turn on again. It would get worse and start up again as soon as I turned it off!
I can't remember if I ever fixed this, but have you tried resetting PRAM, PMU etc? I removed the PMU battery from mine, maybe this solved it? It was too long ago...

Remove the preferences of the energy saver control panel.

THIS is the correct answer. Energy Saver has the ability to turn the computer on and off at selected times.
If the prefs get scrambled, weird shit happens.
it tries to get your attention.
Just like people do

I hadn't booted it in like 2 months though. Suddenly it came alive after 2 months, then the issue started. Hmm.

Well, there is always the possibility that something else less likely has gone wrong, but a simple trashing of prefs is a common first repair step.

I remember that I was trying client/server software but I didn't get the internet connections to work. I trashed the preferences of I think the AppleTalk, TCP/IP, and Internet control panels. Then it did what I configured in the control panels.

isnt "reboot after power failure 0/1" part of the PRAM?

I used the ASR method to restore my old settings recently. It was fine for a few days, then whammo, it starts up in the middle of the night again. I reset the PRAM and everything too. Trashing the preferences doesn't seem to work either.  ???
