As Paul said, hibernation only works if the machine's BIOS supports it (hw.acpi.s4bios = 1) AND you've already prepared a suitable disk area, usually a separate slice (DOS partition) or as a file in a 'doze slice. To make even a vaguely informed guess as to whether hibernation and/or acpiconf -s3 (suspend/resume) might work, we'd need to know: What version of FreeBSD on which architecture? (output of 'uname -a') What make and model of laptop? (someone may know if that one works) Whether it runs a single or multiple CPUs? (see /var/run/dmesg.boot) The output of 'sysctl hw.acpi' ? cheers, Ian _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
