[Bug 1873083] Re: Lenovo Yoga C940 frequently does thermal shutdown
While my problem is not exactly the same, i feel that it's so closely related as to not warrant a separate bug. I have a thinkpad x1 extreme gen3. Whenever i suspend, upon waking up, it shuts down: thermal thermal_zone3: critical temperature reached (128 C), shutting down almost always zone3, sometimes zone4. This is on my focal install, but i tried on a pristine focal live cd, as well as a groovy daily live cd (from sept 26th), with the exact same result. Groovy has thermald 2.3. I *know* my laptop is not in overheat at that point. I can do this from a cold laptop, on battery or on power at 100%, doing fine with temperatures way low (~40 degC), suspend and wake up 10 seconds later _and i still have that behavior. Whatever that sensor is reading did not go from 40 to 128 in 10 seconds of suspend. I suspect a single bad reading when it wakes up trips everything up. I've tried thermal.nocrt, or thermal.crt=150, as kernel command lines (and checked when booted that they were applied). That seems to only impact the acpitz-acpi-0 zone, nothing else, and it still powers off when waking up. removing module int3403_thermal removes thermal_zone[1-8] in /sys/class/thermal (interestingly, sensors still returns the same set, so either those zones aren't to do with the cpu or anything else sensors returns, or sensors goes through something else to get its values?) and suspend now works fine. happy to do some more digging, i'd obviously prefer to un-blacklist this module but now at least i can suspend -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1873083 Title: Lenovo Yoga C940 frequently does thermal shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1873083/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi! I have C940-14IIL, running under Fedora 32 and I am very pleased by this laptop. Everything is OK, except shutdown/reboot (workaround i915.enable_psr=0 kernel option), fingerprint reader (do not care) and overheating shutdown. I have resolved my overheating problem by installing the last version 2.2 of thermald from Github and automatically creating config bydptfxtract (https://github.com/intel/dptfxtract). The bydptfxtract create 10 different thermal-conf.xml. I have tested all of them and I am attaching the most successful of them. I did a stress test with full load for 10 minutes. Following is the uptime output: 14:47:46 up 18:57, 1 user, load average: 8.49, 9.10, 7.25 During the test temperature vary around 75-80 degree - something that I could not imagine before installing the thermald. One virtual machine and a minute of compilation or R calculations would certainly cause overheating shutdown. Actually, as far as can explain the results, the thermald do a CPU scaling of the CPU speed in range 2.5-2.8 GHz - about 1 GHz below the maximum speed - something that I definitely agree. Scaling is done after the rise of the temperature and I do not experience any inconvenience, troubles or interruptions with the lower speed. ** Attachment added: "Thermald conf file" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1873083/+attachment/5387703/+files/thermal-conf.xml -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1873083 Title: Lenovo Yoga C940 frequently does thermal shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1873083/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

No, normally it's below 60C. I can get it to 80C (and shutdown) when the AC is plugged in and charging the battery and I load my CPU a lot at the same time.
