G4 with Tiger won't stay turned off !

Message #1 - Posted 2005/07/08 - SpamHog

I just installed Tiger on a G4
and it's great,
'cept the Mac now
WON'T STAY BLOODY TURNED OFF!

It does shut down OK
(real shutdown, not suspend)
but after 15-20 minutes
it boots up all by itself !

This started after the Tiger upgrade, never happened before.

I looked up and unchecked / disabled all the usual preferences related to automatic booting, rebooting after a power cut etc. but I could not find any that could explain this behaviour.

Additional info:
- if I unplug the network cable, the machine stays off
- however, another G4 next to it just got Tiger installed, and stays off if I tell it to
- both machines are peers (with another couple of computers on the same network), and I think they *should* be set up identically!

What should I look at next?

It sounds like the machine is being woken-by-LAN by the other machine. Is it trying to access it for some reason?

Thank you Alex!

Quite likely, but I'd rather avoid messing with other machines or curtail users' behaviour. It's this comp that should stay off, even if others try to bother it.

Also, I just saw this: "On Mac OS X you can use the Fink wakeonlan-pm package (currently only available in the unstable branch). [...]" ( http://tinyurl.com/7ddm).

This makes me wonder if a wakeonlan command was somehow ADDED to Tiger, that wan't included before. The network browser could be set up as to automatically invoke it if a known machine fails to respond. BTW - such would be necessary, as no one around here knows the MAC address of ANY interface...

Either way:

* How can I make sure WOL is activated?

* Once I know it is, how do I deactivate it?

* Does it perhaps WOL also go under some other, Mac-only, user friendly but confusing name in a GUI menu :-) ??

TIA,

Filippo

Thank you! Will do, try a couple of other things, and feed back here!

Thank you Al! I really needed to be reminded that a computer without power will not run! Who cares if settings are messed up? Just hit the button! Same for rebooting, reinstalling the operating system etc etc. No unnecessary information or understanding required! The ideal piece of advice!
