At the time we have disabled, hybernation would fail way too often.
There was a very high failure to resume rate, across e.g. 1000
hybernate-resume cycles, on Ubuntu certified laptops in collaboration
Currently, the state of the art is the deep suspend state, rather than
hybernation states. Thus modern laptops sleep is close to hybernation
in many ways, w.r.t. power usage. However, not the security.
