"Low battery" is a better default shutdown condition than "on battery", and for most UPSes, you're looking at roughly 30% capacity remaining at that point. More advanced UPSes will allow the user to configure the trigger for the low battery signal (either time remaining, or battery percentage). It sounds like you are looking for the "shut down the box early" case mentioned in Section 7.2 of the link that Arnaud sent before: http://www.networkupstools.org/docs/user-manual.chunked/ar01s07.html -- Charles Lepple clepple@gmail _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
