> Did you try to set OS override to any of the values, recognized by > your BIOS, with most interesting being "Windows 2001 SP2", "Windows > 2006" and "Windows 2009". Yes, I tried this a while ago, before messing with the DSDT. I figured it was unlikely that Dell shipped a DSDT which leads to 0°C readings under Windows. Alas, no OS override seemed to change anything. The CPU was running just as hot and the temperature reported by ACPI remained 0°C. Now that I have tried Linux, I can confirm that there, too, the temperature is 0°C. The DSDT is completely broken. > Additionally, could you, by any chance, replace _TMP method in TZ01 > with the snippet below and let me know what the result is: I am running with that change right now. It seems to have the same effect as my own fixes: hw.acpi.thermal.tz1.temperature works and returns a temperature that agrees with dev.cpu.X.temperature. No other obvious changes. All temperatures are still in the same ranges. - Bartosz
