when i try to use "standby" in linux, the screen goes blank and immediately resumes. my dmesg shows this error: which after some googling, i've found that this can mean that the computer doesn't support the S1 sleep state. when i tried going into "standby" mode in windows, it seems to just go into S3, but windows doesnt ever tell me or let me choose which acpi state i'm going into, so i'm not totally sure what windows is doing. is it possible that my laptop(its a sony vaio, btw.) just doesnt support the S1 power state or is this very unlikely?

Hi,

Not really familiar with the Vaio myself but you might try checking the bios to see if it let's you choose between S1 and S3. Most bios will allow that and may help Linux. Also you might have a driver module loaded that is causing problems with acpi but that's just a guess.

Make sure syslog and cron is stopped before going into stand-by. Browse through the /proc/acpi directory to find out what power levels the notebook can do.

hmmm... the output of "cat /proc/acpi/sleep" is "S0 S3 S4 S5", so i guess i really cant do S1 on this laptop? my bios doesnt have much in it besides boot sequence and date/time, so i couldnt find anything there.

how come the 2.6 /sys/power/state thing says "standby mem disk" when i cat it? shouldn't it only say "standby disk"? i think /proc/acpi/sleep is better, i definitely like using the number of the sleep state instead of "standby" or "mem"

Hello!

As I stated in another thread, I have the same problem. However, in Kubuntu, it works. But in Vector, it doesn't, so it seems that there is some configuration problem.
