[ltp] ACPI + TP600e

It is not possible to turn on/off the fan it self, but one can change the trip 
points by using (at your own risk):

echo '63:0:0:45:0' >/proc/acpi/thermal_zone/THM2/trip_points

The normal trip point is 36 C. This trick will probably shorten the lifespan 
of the laptop, but all 600's are already 4-5 year old anyway.

THM2 has a temp of about 43 to 44 C under normal condition of work.

I have just posted a contribution to thinkwiki about how to activate the sound 
device with pnpacpi:

echo 'activate' >/sys/devices/pnp0/00:05/resources
echo 'activate' >/sys/devices/pnp0/00:06/resources

Best regards
