FWIW, I had NetBSD installed prior to installing FreeBSD on this laptop, and there suspending worked just fine (modulo PCMCIA issues). > Are you enabling APM first, with 'apmconf -e'? No. Do I need to? I didn't need to do that when my laptop ran NetBSD, and foolishly (?) I assumed I didn't have to fiddle anything extra to enable power management in FreeBSD either. It appears problematic to find the default state for the variables apmconf provide an interface to... Hmm, doing 'apmconf -e' may have solved at least part of my problem. I think I need to experiment some more before the final conclusion, but now I have at least once managed to take the PC into and out of the suspend state, although the behaviour appears somewhat erratic (sometimes it "auto-resumes" after about a minute...). > How are you trying to suspend, with 'zzz', or 'apmconf -z', or by > closing the lid? Before I did 'apmconf -e', zzz, pressing the "suspend" function key or closing the lid all have the same effect -- the machine froze. > > On which mailing lists should I listen to to be aware of any > > progress on solving this problem?

Ok, sounds like I need to subscribe there. Thanks! - Håvard
