System sometimes fails to wake from suspend

[Wollie]

If it happens again you could post the logs as described here

Not waking up from sleep - how to troubleshoot help request

Standby/Suspend journalctl --boot -1 | sed -n -r "/Starting.+Suspend/,/Finished.+Suspend/p" Sleep/Hibernate journalctl --boot -1 | sed -n -r "/Starting.+Hibernate/,/Finished.+Hibernate/p" Here you can get a list of all boots with date and time: journalctl --list-boots --no-pager Then you can target the correct boot number (0, -1, -2, -3 etc.)

or you might have a look into following troubleshooting wiki:
