Hi, I posted a question to the freebsd forums (under mobile computing) in which I was seeking help with a old laptop (hp pavilion ze2000) because of fan noise. The problem is not really that the fan is too loud, although that is part of it, it is that it cycles frequently (about every 21 sec, at average use). I seems to me now that maybe here would be more appropriate. I am having trouble finding information about the acpi functions in particular. So I thought maybe I could get help here. For instance, according to the information below, is the passive cooling set to start at 85.0C (Celsius) which would be 185 Fahrenheit? Is this very hot to start to cool down passively? Why is active cooling set to -1? Where do I find the definitions of these things... like the flags? ----sysctl -a | grep thermal hw.acpi.thermal.min.runtime: 0 hw.acpi.thermal.polling_rate: 10 hw.acpi.thermal.user_override: 0 hw.acpi.thermal.tz0.temperature: 60.0C hw.acpi.thermal.tz0.active: -1 hw.acpi.thermal.tz0.passive_cooling: 1 hw.acpi.thermal.tz0.thermal_flags: 0 hw.acpi.thermal.tz0._PSV: 85.0C hw.acpi.thermal.tz0._HOT: -1 hw.acpi.thermal.tz0._CRT: 95.0C hw.acpi.thermal.tz0._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 hw.acpi.thermal.tz0._TC1: 2 hw.acpi.thermal.tz0._TC2: 3 hw.acpi.thermal.tz0._TSP: 50 Any insight would be appreciated, -eg
