    Jupiter not reading the right temp sensor.


    As a rule I install Jupiter Power Management on all my laptops so I can keep an eye on temp and set the processor to "Power On Demand" to save a bit of battery when unplugged.
    I've installed Jupiter on 3 nc6400's over the last few days and with my personal nc6400 the temp reads 16*C, the other two are 45*C(more normal IMHO). I did an "acpi -t" on my system and sensor 3 is at 45*C but sensor 4 is the 16*C sensor and that looks like the one that Jupiter is getting it's readings from instead of sensor 3. Is there anyway to change that or should I just reinstall or what? Thanks.

    Do you have lm_sensors package installed and configured? If so, what does the command "sensors" show?

    acpi gives me this:
    Thermal 0: ok, 20.0 degrees C
    Thermal 1: ok, 30.0 degrees C
    Thermal 2: ok, 39.0 degrees C
    Thermal 3: ok, 45.0 degrees C
    Thermal 4: ok, 16.0 degrees C

    "sensors" gives me this:
    temp1: +16.0C (crit = +256.0C)
    temp2: +44.0C (crit = +105.0C)
    temp3: +38.0C (crit = +105.0C)
    temp4: +31.0C (crit = +105.0C)
    temp5: +20.0C (crit = +110.0C)


    Jupiter is reading #4 in acpi but I'm pretty sure that #3 is my CPU temp. If we go by lm-sensors then Jupiter is reading sensor 1 when it should be 2 for the CPU temp.

    Depending upon the motherboard, you can get a sensor reading for each core as well as each RAM stick. Usually when you first install lm_sensors, as root you will run the command "sensors-detect". That will configure the sensorsd daemon properly. Then the "sensors" command should show something like this:
    Code:
    i5k_amb-isa-0000
    Adapter: ISA adapter
    Ch. 0 DIMM 0: +68.5C  (low  = +97.0C, high = +124.0C)  
    Ch. 1 DIMM 0: +70.5C  (low  = +97.0C, high = +124.0C)  
    Ch. 2 DIMM 0: +63.0C  (low  = +97.0C, high = +124.0C)  
    Ch. 3 DIMM 0: +58.5C  (low  = +97.0C, high = +124.0C)  
    
    coretemp-isa-0000
    Adapter: ISA adapter
    Core 0:      +33.0C  (high = +78.0C, crit = +100.0C)  
    Core 1:      +38.0C  (high = +78.0C, crit = +100.0C)  
    Core 2:      +32.0C  (high = +78.0C, crit = +100.0C)  
    Core 3:      +37.0C  (high = +78.0C, crit = +100.0C)  
    
    coretemp-isa-0002
    Adapter: ISA adapter
    Core 0:      +28.0C  (high = +78.0C, crit = +100.0C)  
    Core 1:      +28.0C  (high = +78.0C, crit = +100.0C)  
    Core 2:      +24.0C  (high = +78.0C, crit = +100.0C)  
    Core 3:      +17.0C  (high = +78.0C, crit = +100.0C)
    As you can see from the above, I have 4 memory sticks and 2 quad-core processor chips.

    lm_sensors was installed by default when I installed Hardinfo so there's was no config to it. Not going to worry too much about it since the laptop is running ok but it'd still be nice to see the right CPU sensor instead of something else showing up in Jupiter.

    Ok. In any case, run the "sensors-detect" command, and you might want to review the contents of /etc/sensors*.conf (it may be sensors.conf, or sensors3.conf, etc) file.
