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,
