** Description changed: Ubuntu 20.04. Thinkpad W530. I had `tlp` installed with acpi-call-dkms, which led to errors as described here: https://bugs.launchpad.net/ubuntu/+source/acpi-call/+bug/1953261/ (Some details are available there with my posts.) I removed these two packages and then took the advice of @linrunner to use the PPA to install tlp 1.5.0-2. I did not install acpi-call-dkms 1.2.2, figuring I'd just wait for kernel 5.17: https://bugs.launchpad.net/ubuntu/+source/acpi-call/+bug/1953261/comments/21 The result on first use after `tlp` install, was that I had a sudden shutdown followed by reboot. I didn't have a battery in my laptop and so assumed the power had gone out. So, I shut down, put the battery in and restarted with the laptop connected to AC. After some time (2 hours?) I had another sudden shutdown/ reboot. They both felt as if the power plug had been pulled. It was at the third shutdown/reboot that I decided to remove `tlp`. I haven't had a problem since. + + `tlp` is no longer installed, so `apport-collect` isn't allowing me to + collect any more information. Let me know if there's something else I + can do.
