I have the same notebook, I have the same problems,here's what I found, it may help you > I posted a while back about getting a thermal trip whenever I take the > machine off ac.

Also, Linux (Suse 10.0) works fine. No thermal trip. I do a sysctl hw.acpi.cpu.cx_lowest=C2 before I put the machine off ac, it _seems_ to help > > In fact on suse I see other thermal zones with signicantly lower temps > (e.g. tz0 is typically <40C while freebsd amd64 current as of today is > > >50C).

Add hint.acpi_throttle.0.disabled="1" to /boot/loader.conf, it worked for me.
