Hi, >>>>> On Fri, 08 Feb 2008 07:58:39 -0500 >>>>> "Alexandre \"Sunny\" Kovalenko" <alex.kovalenko@verizon.net> said: alex> hw.acpi.thermal.tz0.passive_cooling: 0 Perhaps, your ACPI BIOS doesn't provide _TSP, _TC1 and/or _TC2 which are required to work passive cooling. 8-CURRENT has sysctl mibs for _TSP, _TC1 and _TC2 which are user overridable but are blocked on user_override mib. With them, you should be able to use a passive cooling without your ACPI BIOS support. But, it is not MFC'ed yet. You can try the following change: http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/acpica/acpi_thermal.c.diff?r1=1.65;r2=1.66 You need to have some knowledge to set them correctly. Just for reference, my laptop has _TC1=0, _TC2=12, _TSP=40.
