>From my understanding, I can see that thermald is detecting the passive trip point temperature being reached at 75 degrees C and then it attempts to move to cpufreq index position 3; so it seems to be trying to do some passive CPU frequency switching.

In the earlier analysis we saw that even at 20% CPU load your machine is close to this temperature. So, we can conclude that slightly busy CPU already into the thermal danger zone and informing the OS to start attempting passive cooling strategies. Key facts we can draw from this: At 20% utilization your machine is already moving into the zone where the designers of the machine believe that fan control is not sufficient and hence is triggering passive cooling strategies. That really tells me that your machine is having some cooling issues between the CPU and the fan. This implies that one should check that there is sufficient thermal paste between the CPU and the heat pipe. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1491797 Title: Shuts down when supposed to suspend as a reaction to self-caused overheat, session lost To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1491797/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
