I recently upgraded to Ubuntu 22.04 and my Dell laptop started shutting down unexpectedly. It seems like my CPUs are spiking to 100%, then shutting down.

In many cases I can’t do the most simple task, like opening VS Code, in others it shuts down seconds after I log in. Sometimes I can see an error saying it shut down due to temperature, but the machine is always very cool to the touch.

This never happened on Ubuntu 20.04.

Laptop Specs:

  • Dell Inc. Inspiron 15 3510
  • 16 GB Memory
  • CPU: Intel® Pentium(R) Silver N5030 CPU @ 1.10GHz × 4
  • Graphics: Mesa Intel® UHD Graphics 605 (GLK 3)
  • Disk: 512 GB
  • Roughly 3 months old.

Here are some useful logs:

    Well, what do your logs say? Keep in mind that Ubuntu-caused shutdown are always logged so you can discover the reason. If nothing is logged, then you have a hardware problem that is coincidentally occuring after the release-upgrade. Warnings about temperature fall under hardware (not Ubuntu) faults.

    The machine being "cool to the touch" doesn't mean the processor hasn't exceeded its maximum temperature. That can all happen on a millisecond time scale. See this, where I have measured a processor temperature increase rate of 800 degrees per second (which obviously would slow down as it gets higher).

    @mchid I installed and ran the package. There was a lot of prompts for probing (All of which I said yes to). This was the result: Driver 'coretemp': * Chip 'Intel digital thermal sensor' (confidence: 9)

    How's your Fan? Rotating, unblocked? How dusty is the inside of the computer (dust is an insulator - keeps the heat in)?

    @waltinator The fan is quiet. I used compressed air to remove any dust if there was any. PC is roughly 3 months old. I have added PC Specs to the question.

Try loading the coretemp module at an earlier stage:

 printf "# BUGFIX: pre load coretemp to fix Laptop Thermal Shutdown Bug\ncoretemp\n" | sudo tee /etc/modules-load.d/bugfix-coretemp.conf

Reboot and see if the problem gets fixed.
