I just yesterday upgraded to Ubuntu 20.04 (coming from 19.10). Everything is working fine, except, that now when I send the laptop into suspend (no matter if closing the lid, using the menu or sudo pm-suspend) the laptop will instead just shut down. This only happens when no AC is plugged in!

Checking journalctl gives no meaningful insights, it just says -- Reboot --.

dmesg gives some ACPI errors, maybe this might be interesting?

Any ideas?

My solution actually was to properly shutdown the computer instead of restarting. So the actual "Power Off" option in Ubuntu. After that, the issue never reoccurred.
