I have an older APC BACK-UPS 500 connected via a serial cable. In the Windows UPS panel it shows, and switches to "On Battery" for current power source when the power is disconnected to the UPS. The other three items in the status are greyed out - I think this is because the UPS is old and doesn't provide this information.
The plugin shows On AC power and says no battery. Disconnecting the power to the UPS does not change the plugin status. Any ideas? Thanks.
