I would have thought the ideal way for it to operate is when you
suspend, it *also* dumps to swap. That way, when you unsuspend it
springs to life really quickly. But, if your power had failed while
suspended, it could unhibernate from swap.
There is a mode like that, it's called hybrid-sleep. It sets up
everything for hibernation, but then just suspends. If the battery runs
out, then the next boot will do a resume from hibernate. It takes
longer to suspend, like hibernate does, but it resumes fast.
You can use it by running "systemctl hybrid-sleep". It isn't supported
by Gnome, I don't know about other desktops.
