Dear Rui, Many thanks for the reply. I have uploaded the data you requested to: http://xlk.org.uk/ext/laptop-data.tar.gz laptop-data.tar.gz contains 4 text files: * acpidump.txt * cool.txt (output of "grep . /sys/class/thermal/*/*" when system is cool) * overheat.txt (output of "grep . /sys/class/thermal/*/*" when CPU overheats. I don't think this file contains any temperatures readings from the CPU though) * overheat_sensors.txt (output of "sensors" when CPU overheats) Please do let me know if you need any more info. (Sorry for the very late reply. I did reply on 1st Oct but it seems that email didn't get through to the list). Thanks again for your help, Jack On 1 October 2012 15:33, Zhang, Rui <rui.zhang@xxxxxxxxx> wrote: > > Can you attach the acpidump output of this machine? > Can you attach the output of "grep . /sys/class/thermal/*/*" both when the > system is cool and overheat? -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
