It happens on my Lenovo T470. Used to happen rarely on Ubuntu 20.04 LTS (once in 2 months) and occasionally on Ubuntu 22.04 (2-3 times per month).
When I plug in / unplug the power cable, the typical sound is played, but still cannot get through to the system and have to force reboot with the power button.
