Yes. FreeBSD, by default, sets up standby as S1 and suspend to S3 because almost all BIOSes support these states. Yours is the first BIOS I have seen that does not do S1. That is really odd. In any case, you have no available ways to cut power when your system is really idle other than powering off. Of course, you may be able to do some power saving with powerd and EST if your BIOS and CPU support those. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
