Unable to configure UPS options

[Melvin Call <melvincall979@gmail.com>]

Hello,

I have two computers, both running Wheezy and the
XFCE4 Desktop. Both have attached UPS devices, and
lsusb shows the UPS attached to each machine. Yet,
on one I have options to configure actions to take
when on battery, and on the other I have no "On
Battery" tab. I enabled the battery monitor plug-in
in the notification area on both, and the problematic
one shows only to be online (no battery present).

I am looking for help to enable the battery option
on the second machine so when the power goes off
the system will shutdown or suspend to RAM at my
choosing. I have compared installed packages between
the two and see nothing significant. What would my
next step be, please?

Regards,
Melvin
