I hope this is the proper list for this issue...
This is an older laptop, has the most recent bios update installed,
currently running 10.0-RELEASE-p14, have tried 11 as well. Err ahem..
Linux runs well on the laptop, and with FreeBSD everything works except
for battery status.
The laptop has a feature where there is an available port on the bottom
for an add on additional battery that I do not own, but I believe may
be the source of the issue, which is the lack of battery status
updates.
Plugged in and fully charged....

Have tried forcing in loader.conf with no effect.

When unplugged the OS seems to recognize that the machine is no longer
connected to 110, the screen dims yet the battery status remains the
same till the computer either runs out of battery or it is plugged back
in, only way to refresh batt stat is to reboot.
By the way, here is sysctl -a | grep batt when unplugged for 30 mins
with moderate usage.

Anyone have any suggestions? FreeBSD is my favorite OS, this keeps me
from using it full time my life style is depended on battery usage,
cannot afford a newer laptop. Just wish I could get this one thing
working.
