[Nut-upsuser] Shutdown after 5 minutes?

[Michelle Dupuis]

If the Windows comment is accurate (i.e. does not happen under windows) then
disregard this comment.  Otherwise...

We've seen a UPS with a new set of batteries, reporting full charge.  Then
when under load (upon power failure) the unit shuts off.  The root cause was
one of the 4 batteries in the unit was defective.  Although it showed full
voltage, it collapsed under load causing the UPS to turn off immediately.
Replacing the battery solved the problem.

thanks for the warning.. :)

I've been needing to snoop on the com port when the windows program is 
running.  It _doesn't_ appear to do it when it is being monitored with 
windows.
