systemctl-suspend-then-hibernate

systemctl suspend-then-hibernate [OPTIONS]

systemctl suspend-then-hibernate first suspends the system to RAM, then automatically wakes up and hibernates to disk after a configured delay. This provides fast wake-up when used shortly after suspension, while protecting against data loss if the battery depletes during extended sleep.
The delay before hibernation is configured in /etc/systemd/sleep.conf via the HibernateDelaySec= option (default varies by distribution).

Requires both suspend and hibernate to work properly. Needs sufficient swap space for hibernation. The delay timer wakes the system to hibernate, consuming some power. May not work reliably on all hardware.

The suspend-then-hibernate subcommand combines the benefits of fast suspend wake-up with the safety of hibernation for long idle periods, ideal for laptops left sleeping overnight.
