>Description:
Following a failure of external power to a laptop, a few ACPI-related
error messages appear on the console, the system incorrectly things that
acpiacad0 is still connected, and the system incorrectly thinks that
acpibat0 is still fully charged and not discharging.

>How-To-Repeat:
Boot.  See the following acpi-related messages:

Have a power failure so the laptop starts running on its internal battery.

Note that envstat(8) thinks the external power is still on and the
batter is not discharging:
