Some system logs looked like they weren't getting the normal flow of messages and 'systemctl status' for the suspend.target and systemd- suspend.service showed they thought the system was suspending/suspended. This was around 07:36. I left the system most of the day until I could investigate. I noticed the dmesg showed "Suspended for 23820.656 seconds" when it resumed/failed to suspend immediately. After a lot of digging and saving command output of interest at 18:33 I did: sudo kill $(pidof systemd-sleep) the system immediately suspended. After nearly a minute I pressed the power button and the PC instantly resumed. dmesg reported "Suspended for 43 seconds" which is correct and network-manager correctly returned to connected state. --- tj@T300CHI:~$ nmcli gen STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW WWAN asleep none enabled enabled enabled enabled tj@T300CHI:~$ systemctl status suspend.target Failed to suspend system via logind: There's already a shutdown or sleep operation in progress tj@T300CHI:~$ systemctl status systemd-suspend.service systemd-suspend.service - Suspend Loaded: loaded (/lib/systemd/system/systemd-suspend.service; static; vendor preset: enabled) Active: activating (start) since Fri 2018-01-19 00:56:05 GMT; 17h ago Docs: man:systemd-suspend.service(8) Main PID: 23868 (systemd-sleep) Tasks: 1 Memory: 536.0K CPU: 6ms CGroup: /system.slice/systemd-suspend.service 23868 /lib/systemd/systemd-sleep suspend Jan 19 00:56:05 T300CHI systemd[1]: Starting Suspend...
