Heh! Not sure why NUT never crossed my mind. I've done it on servers, but on the
"working" system that battery option has always been there and it works when the
power goes out (system shuts down gracefully). If you are correct, then that is
not the working system.
Anyhow, NUT is easy so I'll try that route.
mrr, if you have pointers to developing udev rules, I've had a need for that
knowledge for other reasons in the past so shoot me some pointers if you get
time.
Thanks everyone!
