your thermal doesn't poll.... make it poll like this: |
2 |
echo "2 seconds" > /proc/acpi/thermal_zone/THRM/polling_frequency |
3 |
or wichever thermal zone is in /proc/acpi/thermal_zone. then verify your |
4 |
trip points in the same THRM directory but in the file trip_points. you |
5 |
should see something like this: |
6 |
critical (S5): 105 C |
7 |
passive: 76 C: tc1=3 tc2=1 tsp=150 devices=CPU0 |
8 |
active[0]: 67 C: devices= FN1 |
9 |
active[1]: 57 C: devices= FN2 |
10 |
|
11 |
in the eg passive means that your cpu is downclocked since it has passed 76 |
12 |
degrees C |
13 |
active [0] means that your fan is triggered to on |
14 |
active[1] means that the fan is not triggered and it is shut down. |
15 |
the critical point is when the system shuts down. |
16 |
if the polling_frequency tweak doesn't work then you have another problem |
17 |
(eg i had to compile the fan and thermal module included in kernel since |
18 |
modprobing them would not start the fan). if it works copy the tweak command |
19 |
and put it in some init script (i put it at the start of /etc/init.d/xdm so |
20 |
that i'm sure it loads after acpi, since that file doesn't exists without |
21 |
acpi loaded). |
22 |
then try installing kima if you're using kde and add the kima kmenu applet |
23 |
to monitor some things. you should be able to see that the processor hardly |
24 |
passes 60 degrees while thermal goes high till the passive point and over; |
25 |
if you monitor also the cpu load and freq you should be able to see how your |
26 |
processors reacts to programs. remember to also install the klaptopdaemon |
27 |
since is quite useful in controlling the cpufreq_utils governors and acpi |
28 |
settings. try also the laptop_mode-tools and see if they can help you have a |
29 |
better use for your disk. the last thing that you can also install is the |
30 |
hddtemp for monitoring your disk temperature. |
