From the power manager options you can set up the conditions under which your computer goes to sleep or into hibernation.
I was checking my synaptic but I don't have mate-power-manager.
At this point I demoted LM12 from (hoping for it to become my main OS). I find myself spending more time trying to make LM12 work like LM9 but unfortunately it required more time and skills than what I have.
So, I'm going with other OS for now.
