If you choose Systemd, then go to your BIOS/UEFI setup, and disable S3, S4 and S5 power states. Those power states are sleep, suspend and hibernate. Systemd will now control them.
Jeffrey, do you have a link explaining it with more details? I expected some kind of cooperation of machine firmware and systemd in respect to power management.
I assumed that disabling power states in UEFI setup may make them unavailable for OS.
