Well, I just add the line acpi_toshiba_load="YES" in /boot/loader.conf and reboot.
The sysctl hw.acpi does not show any thing new. The acpi's shown by acpi_toshiba man page continue not to be shown:
[dleal@Descomunal]$sysctl hw.acpi
hw.acpi.supported_sleep_state: S3 S4 S5
hw.acpi.power_button_state: S5
hw.acpi.sleep_button_state: S3
hw.acpi.lid_switch_state: NONE
hw.acpi.standby_state: S1
hw.acpi.suspend_state: S3
hw.acpi.sleep_delay: 1
hw.acpi.s4bios: 0
hw.acpi.verbose: 0
hw.acpi.disable_on_reboot: 0
hw.acpi.handle_reboot: 0
hw.acpi.reset_video: 0
hw.acpi.acline: 1
hw.acpi.battery.life: -1
hw.acpi.battery.time: -1
hw.acpi.battery.state: 7
hw.acpi.battery.units: 1
hw.acpi.battery.info_expire: 5
hw.acpi.cpu.cx_lowest: C1
strangely the hw.acpi.thermal is not present also...
I did acpiconf -i 0 and I was able to see data from the battery. This was nice!
But how can I be sure that I can have my laptop running just on battery without the fear of a unexpected system shutdown? Because last time I did it, a few minutes after boot, the system just switch off without any kind of alert.
