How to restore hibernation on Fedora

Hibernation, also known as “suspend to disk”, is the most efficient power saving mode in terms of energy consumption. On hibernation, the state of the random access memory is stored on disk, and the machine is completely power down. Although efficient, hibernation is commonly not recommended if using a solid state drive, because each time the system enters this power state, a lot of data must be written to disk, which as we know, has a limited number of write cycles. For this and other reasons, as the the low number of machines on which hibernation works reliably on Linux, Fedora decided to disable this power state by default.
