Hi, I have a problem with my laptop, it gets very hot (~70C) after operating for a while. I use FreeBSD-6-Stable, and it has this problem for a long time now. Actually I think it always had it, but I'm fed up with this. I tried various things I read in the mailing list, but I don;t know many things about how acpi handles the fans to control the temperature of the cpu, etc. My sysctl hw.thermal after the changes in hw.thermal.tz0._PSV and hw.thermal.user_override. hw.acpi.thermal.min_runtime: 0 hw.acpi.thermal.polling_rate: 10 hw.acpi.thermal.user_override: 1 hw.acpi.thermal.tz0.temperature: 73.0C hw.acpi.thermal.tz0.active: -1 hw.acpi.thermal.tz0.passive_cooling: 0 hw.acpi.thermal.tz0.thermal_flags: 0 hw.acpi.thermal.tz0._PSV: 90.0C hw.acpi.thermal.tz0._HOT: -1 hw.acpi.thermal.tz0._CRT: 127.0C hw.acpi.thermal.tz0._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 It seems that the device dowes not support setting passive cooling: celeborn# sysctl hw.acpi.thermal.tz0.passive_cooling=1 hw.acpi.thermal.tz0.passive_cooling: 0 sysctl: hw.acpi.thermal.tz0.passive_cooling: Operation not supported by device and it neither supports active: celeborn# sysctl hw.acpi.thermal.tz0.active=1 hw.acpi.thermal.tz0.active: -1 -> -1 Kernel is already loaded with acpi.ko and asus_acpi.ko modules. Any clues how to tackle this? I was thinking if I could set the cpu to run at a lower frequency, when I'm not doing something "heavy" might help. Kind regards, Vassilis --
