In case of thermal problems you will probably see following in /var/log/messages: Jan 8 17:57:48 xxx kernel: acpi_tz0: WARNING - current temperature (76.8C) exceeds system limits Jan 2 23:54:06 xxx kernel: acpi_tz0: WARNING - current temperature (76.8C) exceeds system limits Recently I started to have thermal problems. My laptop has either grown to age or upgrade from 5.1 to 5.2 current acpi code changed something and cooling does not kick in fast enough on rapid temperature rise (i.e. make world or dvd playback) or does not work for long enough. I found that 'sysctl hw.acpi.thermal.min_runtime=300' was good cure for my laptop. best regards, taavi
