I have been trying to get at least some of the Power Management working under Linux, but haven't been too successful. Most important for me:
Spin my fan down. The temperature seems to be at 22°C, so no cooling should be needed?
Unfortunately I don't have any entries in /proc/acpi/fan, does this mean, it can't spin down? Or do I need to load any specific modules for this?
Maybe related: There is only one "trip_point" defined in thermal zone:
[root@frank /]# cat /proc/acpi/thermal_zone/THRM/temperature temperature: 22 C [root@frank /]# cat /proc/acpi/thermal_zone/THRM/state state: ok [root@frank /]# cat /proc/acpi/thermal_zone/THRM/trip_points critical (S5): 110 C [root@frank /]# cat /proc/acpi/thermal_zone/THRM/cooling_mode <setting not supported> cooling mode: critical
Btw... the CPU is an AMD Turion64, and its frequency is scaled down by cpudyn.
