Just have a look to your trip_point: [EMAIL PROTECTED] ~ $ cat /proc/acpi/thermal_zone/THRM/trip_points critical (S5): 95 C passive: 87 C: tc1=1 tc2=5 tsp=10 devices=0xdff72dc4 When reaching 95° my computer starts to shutdown fast. I found more Information on http://acpi.sourceforge.net/documentation/thermal.html Maybe it helps you too. -- Michael Gisbers http://www.lugor.de
