as the lack of shutdown yields visible file corruption and potentially data loss.

The fact that the system powers down instead of just resuming. systemd-logind reports "Power key pressed." but the power key was used to resume, so that I suppose that systemd-logind should have never seen this. 2. The fact that the system is powered off immediately without a clean shutdown. When I use the power button to power off the laptop, I get: Sep 17 19:36:13 zira systemd-logind[17281]: Power key pressed. Sep 17 19:36:13 zira systemd-logind[17281]: Powering Off...
