Hibernation option greyed out in Power settings

Asked by Wise Melon on 2015-01-06

When I go into the Ubuntu Power settings through System Settings, I have noticed that for "On battery power" options that the option "Hibernate" for "When power is critically low" is greyed out. Why is this? Do I need some extra support drivers or something? Or is this some kind of bug? Or...?

Does the system have a make and model?

What is the output of:

free -m; lsb_release -a; uname -a


This is the output from the command:

Do you have the latest BIOS? You have enough swap for your RAM.

Well I now have to update my BIOS it seems as that is probably the problem...
