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.

It _doesn't_ appear to do it when it is being monitored with windows. _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser
