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 Capacity (low): 44 mAh Low/warn granularity: 100 mAh Warn/full granularity: 100 mAh Model number: Primary Serial number: 45148 2008/05/12 Type: LIon OEM info: Hewlett-Packard State: high Remaining capacity: 100% Remaining time: unknown Present rate: 0 mA (0 mW) Present voltage: 16721 mV sysctl -a | grep batt debug.acpi.batt.batt_sleep_ms: 0 hw.acpi.battery.life: 100 hw.acpi.battery.time: -1 hw.acpi.battery.state: 0 hw.acpi.battery.units: 2 hw.acpi.battery.info_expire: 5 dev.battery.0.%desc: ACPI Control Method Battery dev.battery.0.%driver: battery dev.battery.0.%location: handle=\_SB_.C1FD dev.battery.0.%pnpinfo: _HID=PNP0C0A _UID=1 dev.battery.0.%parent: acpi0 dev.battery.1.%desc: ACPI Control Method Battery dev.battery.1.%driver: battery dev.battery.1.%location: handle=\_SB_.C1FC dev.battery.1.%pnpinfo: _HID=PNP0C0A _UID=2 dev.battery.1.%parent: acpi0 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 Type: LIon OEM info: Hewlett-Packard 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.
