311570 2005-01-07 05:11:00 Hey,

When running a dmesg | more command from the console I get the following lines in the middle

ACPI: Fan [FAN] (on)
ACPI: Processor [CPU0] (supports C1)
ACPI: Thermal Zone [THRM] (47 C)


Can someone exlplain what the meaning of ACPI: Thermal Zone [THRM] (47 C) is?

Does this have something to do with temperature sensing?

311571 2005-01-07 05:31:00 what exactly is dmesg?

It might be in the mobo manual whatever it is

dmesg is a linux command listing the hardware on your system.

For example dmesg | grep eth0 would list the details of your system, filtered so only the first network card is displayed

311573 2005-01-07 06:09:00 I don't have a laptop running Linux, so I can't compare dmesg outputs for ACPI, but I am guessing this is your current laptop temperature, and there must be a set point at which the system will up your cooling or shutdown if it goes over temperature.

Someone with a lappy will probably be able to explain this better. :)

Ah ok thanx for the info Ash :)

Chill.

Well, this isn't a laptop.....
:badpc:

Unusual....

If it is the CPU temp thats unusual as I posted recently as my Temperature was showing in the bios as 58

311577 2005-01-07 08:04:00 Well, this isn't a laptop.....
:badpc: Oh ... :rolleyes: :blush:
Hmm ... well I still don't have any ACPI messages like that in my dmesg. Maybe it depends upon motherboard/BIOS support?

You can have a read up more about ACPI and Linux here (http://acpi.sourceforge.net/).

311578 2005-01-07 08:39:00 just ran that on my xandros (debain based) laptop did not get any ACPI messages either I would tend to agree with jen

311579 2005-01-08 00:23:00 The fact that it shows a different temperature is to be expected . :D

The software is different .

The BIOS takes a "number" from the sensor, and does a calculation to come up with a temperature . It's not a scientific instrument . If it's within 10 degrees I would say it's doing pretty well .

The Linux stuff sees the I2C interface and finds a sensor . It gets a number from it, but will be using a default "calibration" table to work out its "temperature" . It would be a fluke if it agreed with the BIOS .

There is a HOWTO about this . . . I read it a while ago . It tells you how to make the temperatures "sensible" .
