It only turns off in extremely rare cases (countable on one hand). The computer does NOT seem to be overly hot. ACPI is enabled. This is also the loadest fan I've ever heard (also on Windows, but then it's not running all the time), it really sounds like a tractor, so it's essential that it's turn off when the computer is cool enough. Here is the output of 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.reset_video: 1 hw.acpi.cpu.cx_supported: C1/0 C2/90 hw.acpi.cpu.cx_lowest: C2 hw.acpi.cpu.cx_usage: 4.05% 95.94% hw.acpi.acline: 1 hw.acpi.battery.life: 100 hw.acpi.battery.time: -1 hw.acpi.battery.state: 0 hw.acpi.battery.units: 1 hw.acpi.battery.info_expire: 5 I note that there is no acpi.fan, but I don't know if there should be one. If I change hw.acpi.cpu.cx_lowest to C1 the fan still does not turn off and now the computer becomes overly hot. The laptop is a Packard Bell EasyNote E3245. >How-To-Repeat: Turn on a Packard Bell EasyNote E3245 laptop with FreeBSD installed. (console or with X-Windows, nothing matters.) >Fix: Turn off computer. >Release-Note: >Audit-Trail: >Unformatted:
