Hi Johan,

what you describe may in fact be the "normal" behaviour of S1 on this
machine. I have a Gericom 1st Supersonic M6-T, and it behaves the same:
fan and display backlight stay on, power button wakes it up, but the
system does in fact consume 30% less power. My machine uses a ATI Mobile
Radeon M6, so I use "radeontool" from http://fdd.com/software/radeon/ to
turn the display off, and "hdparm" to spin down the harddisk, so S1 is
in fact useful for me, e.g. to transport the system over short distances
without powering it down.

The fact that your machine shuts down when you try to wake it up may be
because you have "acpid" running; it seems to notice the press of the
power button when the machine is back up and thinks you want the system
halted. That's why I got rid of acpid (I am also running Debian sid).

BTW, I use the following little script called "s1sleep" to enter S1:

#!/bin/sh

hwclock --systohc
rmmod -a; rmmod -a; rmmod -a
sync; sync; sync
/usr/local/sbin/radeontool light off
sleep 1
hdparm -q -y /dev/hda

echo -n "S1Sleep at: "; date
echo >/proc/acpi/sleep 1
/usr/local/sbin/radeontool light on
hwclock --hctosys 
echo -n "Woke up at: "; date
