Question on how ACPI works
 
I have a question about ACPI...

when I type 'cat /proc/acpi/sleep' I see four states
S0 S1 S4 and S5

when I type 'echo 0 > /proc/acpi/sleep' or echo 1 into sleep nothing happens.
when I type 'echo 4 > /proc/acpi/sleep' the machine shuts off... even though that's supposed to be the suspend-to-disk state... can someone enlighten me on how this thing is supposed to put my machine to sleep?

A shot in the dark - what levels of ACPI does your BIOS support?

Via's website lists it as (its a via P4PB Ultra mobo)

Award BIOS, STR, ACPI, WfM 2.0, DMI 2.0

I can check with Award after I reboot and find out specifically what version etc I have.
