 pm-suspend-hybrid Hybrid-suspend is the process where the system does everything it needs to hibernate, but suspends instead of shutting down. This means that your computer can wake up quicker than for normal hibernation if you do not run out of power, and you can resume even if you run out of power. s2both(8) is an hybrid-suspend implementation.

Hybrid suspend is when your computer does suspend-to-disk and suspend-to-RAM at the same time. So you get the fast resume speed of suspend-to-RAM, but you don't lose your session if you lose power or run out of battery. So in principle, it's better than either suspend-to-ram or suspend-to-disk alone.
