------- Comment #11 from [EMAIL PROTECTED]  2008-05-11 19:53 -------
>From the acpidump in the comment #2 it seems that there only exists the
definition of "critical trip points temperature". And when the temperature
reaches the critical degress , OSPM will perform the criticial shutdown.

What Rui said in comment #8 is right. If the ACPI changes the processor
P/T-state for thermal control, the _PSL object is required, which returns the
passive coolling device list.(Of course the _PSV object is also required.) If
the ACPI turns on/off fan device for the thermal control, the _ALx object is
required, which returns the list of fan cooling device. (Of course the _ACx
object is also required).

Unfortunately the above objects doesn't exist on this laptop. And there is no
cooling device that can be used to cool the system temperature.
