Uhmmm maybe is it a cousin of HAL 9000?

Ok, sorry.

Probably there is a wake event software that still you didn't find.
Also you could try reinstalling the operating system, this could bring
some options to default.



Check in the BIOS that wake on LAN is not enabled.

Actually I'm pretty sure that's it, since I disconnected the lan cable and
the problem went away. But I can't actually find the LAN wake setting! I
see the list of other wake events (ps2 keyboard, etc) but it's not in there!

Maybe Windows programs the LAN chip, just before shutdown, for any required
behavior.

If I go to Device Manager, and look at my NIC, there are properties
in there, saying "OS controlled" for Wake on LAN. That dialog says my WOL
is currently Disabled.

PME is used by the actual NIC chip, to signal to the chipset, to wake up.
(PME is the same kinda thing they used to put on that three wire WOL cable.
Now it is a bus signal.) The NIC chip runs off a derivative of +5VSB, to
get the necessary power to look for Magic Packets or to look for "any
activity". Some NIC chips have multiple waking methods, while others
are quite restricted as to what will wake them.

Yes, thank you, that was exactly it! I'd even diabled that once before but
a long time ago. Anyway it finally stays off now! Only question now is
why my router/modem would be sending magic packets after every shutdown...

It probably isn't. As Paul said, some NICs have several methods of
'waking' the system, so it could just be any activity on the port (eg
the modem/router simply seeing if there's anything there.) You could
test that with a cross-over cable direct to a 2nd PC, for example.
