Try enabling the ACPI_BATTERY layer and ACPI_LV_ALL_EXCEPTIONS level in
/boot/loader.conf:
debug.acpi.layer="ACPI_BATTERY"
debug.acpi.level="ACPI_LV_ALL_EXCEPTIONS"
debug.acpi.enable_debug_objects="1" # I assume this is how you turn
on ACPI debugging without recompiling the kernel with 'options ACPI_DEBUG'
and running 'sysctl hw.acpi.battery' again. Post /var/log/messages ACPI
messages about battery here.
