I did (see another message). And, as I expected, it didn't make any
difference. What _would_ make a difference, would be to have both
apmd and acpid running at the same time. The two are not compatible
(at least not with a BIOS that support both).

Sorry, I was imprecise. I meant to say "Dell BIOSES past a certain
release number (which I can't remember, but it was first released
sometime last summer) do no longer support APM".

If I could, I would have done the same. APM always worked well for me
in the past. However my D600 was bought in March this year, and I
weren't given any choice in the matter...:-/

Yup, I get events for lid, AC plug out and plug in, battery (on and
off, presumably), and "processor" (change of speed when plugging out
and in).
Thanx!

Check for both of them.

It looks like I'm able to wake it from S3 suspend with a short press
on the powerbutton. I think the reason I'm not seeing anything, is
that the display doesn't come back on.
When it's running, one press on the powerbutton takes it into a
shutdown. A fairly tidy one. I preserves the KDE session.
A long (more than 4 second) press on the powerbutton, always switches
the machine off. I've been told that that's standard BIOS behaviour,
and it certainly beats unplugging the battery pack.

That's pmdisk, which at least one person on the acpi mailing list,
wants to die, die, die, as I've understood.
There's a pretty good explanation of the three software suspend
systems in linux (swsusp/acpi, pmdisk, and swsusp2), on this list:

I haven't tried that one recently. How much power do you save?
I sort of thought only s3 and s4 where worthwhile?
I'll try it tonight and see what happens.
