So if it is a bug, it is probably an upstream bug. However, unless it used to work, or something bad happens, this is sort of an academic failure. I suppose if you ran Windows on the box and it displayed a changing temperature via ACPI but Linux does not, then it would be more interesting. It would be good to verify that ACPI events in general are working on the box -- eg. the power button etc -- as a failure there would also be more interesting than unchanging temperature. -Len
