Description

Note: I'm unable to downgrade, mainly because this causes other issues like a really loud fan and HDMI issues that have been fixed in this release. are you able to downgrade to help us find the difference between these two BIOS versions? If yes, then please attach the acpidump output and "grep . /sys/class/thermal/thermal*/*" for both old and new BIOS. @Zhang Rui Going to try, but if I'm not mistaken it is impossible when a certain switch has been turned on in the BIOS. Will let you know! please attach the acpidump and output of "grep . /sys/class/thermal/thermal*/*" for the new BIOS. please also attach the dmidecode output Created attachment 275049 [details]

thermal
@ Zhang Rui: done. :) ThermalZone (TZ0) { Method (_TMP, 0, Serialized) // _TMP: Temperature { If ((ONEW == Zero)) { Return (0x64) } Return (0x07D1) } Method (_HOT, 0, Serialized) // _HOT: Hot Temperature { Return (0x07D0) } } The ACPI thermal zone is total crap on this NUC. it just returns static value, thus it will never be able to report real temperature. It is apparently a BIOS bug. can you please check if there is any new BIOS available? or can you please disable the ACPI thermal control in BIOS? @Zhang Rui Thanks for looking into this issue! :) Seems more people reported this in the forum, hope the new BIOS indeed fixes this error. I'll try to update the bios as soon as possible and report back to you. *** This bug has been marked as a duplicate of bug 199147 *** |
