@makeworld 20s from suspend sounds more like 20s from hibernation and not suspend:
> Suspend does not turn off your computer. It puts the computer and all peripherals on a low power consumption mode. If the battery runs out or the computer turns off for some reason, the current session and unsaved changes will be lost.
> Hibernate saves the state of your computer to the hard disk and completely powers off. When resuming, the saved state is restored to RAM.
