   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....
   acpiconf -i batt
   Design capacity:        4368 mAh
   Last full capacity:     4368 mAh
   Technology:             secondary (rechargeable)
   Design voltage:         14400 mV
   Capacity (warn):        219 mAh

   OEM info:               Hewlett-Packard
   State:                  high
   Remaining capacity:     100%
   Remaining time:         unknown

   sysctl -a | grep batt

   Have tried forcing in loader.conf with no effect.

   hw.acpi.battery.units=1

   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.
   debug.acpi.batt.batt_sleep_ms: 0
   hw.acpi.battery.life: 100
   hw.acpi.battery.time: 75
   hw.acpi.battery.state: 1
   hw.acpi.battery.units: 2

   and acpiconf -i batt
   Design capacity:        4368 mAh
   Last full capacity:     4368 mAh
   Technology:             secondary (rechargeable)
   Design voltage:         14400 mV
   Capacity (warn):        219 mAh
   Capacity (low):         44 mAh
   Low/warn granularity:   100 mAh
   Warn/full granularity:  100 mAh
   Model number:           Primary
   Serial number:          45148 2008/05/12

   State:                  discharging
   Remaining capacity:     100%
   Remaining time:         1:15


   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.
