Well, the hw.acpi.thermal is not shown in the sysctl hw.acpi list. Maybe 
that means that my MB does not have that kind of sensor. But if not, is 
there a way to control the CPU fan speed according to CPU work? It seams 
to me that the CPU fan is always with the same velocity. And when I had 
windows installed in this laptop I remember that when some complicated 
apps were running the sound of the fan was different.
Regarding the battery, do do you think that with the following list I 
can monitor the charge and be sure that I will not have an unexpected 
shutdown if I run my laptop just on battery?
