Hi there,
I have an Acer 4810tz / intel vga  (i915) , BIOS 2.30 (the latest is 2.31)
Processor is dual core u4100 , running on 1200Mhz (ondemand cpufreq policy),
max 1300Mhz.

Problem: the fan is alway on and I see nothing fan related in /proc - but an
empty dir. I do not know if it is normal.
 I have low cputemp values. Average temperature: 37-45 C, the box usually
used for typing scripts.
On boot there is a slight noise difference but that may be the hdd spin.
Polling frequency is not set, but if I set it to any value it does not
change fan activity.
I can not echo new values to trip_points for I get input/output error.
echo 98:90:86:80:60 > trip_points
bash: echo: write error: Input/output error
(The same if I put the values between "" use or omit -n)
The trip points (see bleow) hint about passive mode, but that is the most.

[root@irulan TZS0]# cat /proc/acpi/thermal_zone/TZS0/

trip_points:
   critical (S5):           98 C
