Re: Dell Latitude LS / FreeBSD 6.1 - overheated, shuts down

I read what Alexandra says about what seems the same problem to me,
and I have a few questions:

What are the 'thermal zones' that ACPI recognizes?
While Alexandra has tz0, tz1, and tz2, I only have tz0.

Is there some way to recognize 'this is the CPU, this is the disk', etc?
So that you can tell, Alexandra, that it's the _disk_ overheating.

I was watching my hw.cpi.thermal, and one second it said

	hw.acpi.thermal.tz0.temperature: 6.0C

and the next second it said

	hw.acpi.thermal.tz0.temperature: 247.0C

resulting in the above warning and shutdown.

Is this really possible? Can my CPU (disk?) have the temperature of
6C? Can it have 247C? What I _suspect_ is that the temperature
_monitor_ itself has gone crazy ...

What would be a reasonable figure?


	Thanks for any hints
