Bug Description
[Ubuntu 8.10]
Hello,
I recently got a brand new Toshiba Satellite L350 (Intel Centrino Core duo 2). All hardware is working really good on Ubuntu 8.10, except the fan.
I noticed that fan starts to run, apparently for no reason, and never stops.
This happens always (but not only in this case...) when I run synaptic or when I'm updating Ubuntu.
Can someone tell me why this happens?
Reading forums, I installed the CPU temperature applet but it's always at 0°C - Is it working fine? The laptop never seems too hot.

I have a Toshiba Satellite A305-S6898, and I share the same problem.
The problem is that there is no temperature reading for the CPU, that's why it shows 0°C like the original bug reporter says.
After installing lm-sensors, and running 'sensors-detect' the module 'coretemp' was suggested to be loaded.
Loading it I now get the following output from 'sensors':
$ /usr/bin/sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +0.0°C (crit = +92.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +52.0°C (high = +85.0°C, crit = +85.0°C)
coretemp-isa-0001
Adapter: ISA adapter
Core 1: +51.0°C (high = +85.0°C, crit = +85.0°C)
running 'acpi -t':
$ /usr/bin/acpi -t
Battery 0: Full, 100%
Thermal 0: ok, 0.0 degrees C
I also tried adding 'acpi_osi="Linux" ' to the kernel options, as this was said to help with this issue, but it does not solve the problem in my case.
With no temperature reading, the fan does not work properly.
Why is the CPU temperature reading module 'coretemp' not loaded as part of a normal Ubuntu laptop installation?
Is it automatically detected and loaded in Jaunty?
