sleep states - maybe a dumb question...

Dear folks,

maybe this is a very dumb question, but I did not find an answer in the docs. (or I was not looking at the right place)

I see two different sleep-state capabilities on my laptop (run by a transmeta cursoe CPU) running 2.6.4 vanilla kernel and a debian unstable system.

# cat /proc/acpi/sleep
S0 S3 S4 S5
# cat /sys/power/state
standby mem disk

as I understand 'standby' is synonymous to 'S1', which is not showing up in the /proc version...

when issuing echo -n standby > /sys/power/state the system acts as if it would go to standby (switch to console, some output saying so, etc.) but resumes immediately.

what does that mean?
does my laptop lack S1/standby capability?

thanks for an explanation

Bug in Patricks code. It should not announce standby when no S1 is available. Oh and it indeed is very igly to have 2 interfaces for same thing; hopefully that will get fixed, too.
