Prevent Suspend/Hibernate on 16.04

Hi all, recently upgraded to 16.04 with Jarvis and previously I had suspend/hibernate turned off or prevented. I made the changes in xfce but the NUC is still going into hibernation mode after 15-20 minutes of inactivity.

Is there a way to turn the suspend/hibernate off in 16.04? Just makes life easier for the kids to use Kodi it if it’s active all the time.

thanks
