how do I change thermal_trip_points for acpi?
Hi all. It seems a lot of people are having trouble with power management and their laptops. I think I have everything working pretty well except my fan is constantly running. I have checked my thermal_trip_points in /proc/acpi/thermal_zone/THRM/thermal_trip_points
I run this command: cat trip_points
and get these temperatures:
critical (S5): 100 C
passive: 99 C: tc1=2 tc2=3 tsp=100 devices=0xc1229120
active: 65 C: devices=0xc1229aa0
active: 55 C: devices=0xc1229bc0
active: 40 C: devices=0xc1229ce0
I want to change the active  up some degrees because the computer never runs below 40C.
I found a page that said you can change the values by doing this:
echo "x: > trip_points" where x equals a value in celcius. I do this and it appears to change values but nothing happens and values change back after a while.
Thanks ahead of time.

ok I don't know why the faces come up at end but it is supposed to be x's seperated by semicolons. HMMMM.

oh...yeah one more thing. I figured out how to manually turn off fan with this command in this directory: /proc/acpi/fan/FAN1/ -------- echo "3" > state
this shuts off fan completely. But I think it disables the trip_points thus it could seriosly endager my computer if used imprudently.
