>Description:
        xbattbar looks for the string 'charging' in a property of an 'acpiacad'
        device. This does not always exist:

        $ envstat -d acpiacad0
        connected:         ON

        As a result, my AC adapter is not detected.
>How-To-Repeat:
        Run 'xbattbar' on a machine with ACPI but not apm@acpi
>Fix:
        Unknown, but this is a major flaw in the envsys API.
