Re: No Thermal

[Len Brown <len.brown-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>]

See if your BIOS has a SETUP setting to boot an ACPI-enabled OS.  If so,
enable it.

after that,you can dump the DSDT with acpidmp and disassemble it with
iasl -d and poke around in the AML to see what the BIOS thinks it
supports.

see http://acpi.sf.net for pointers
