Every time I start the 4 hour endurance race in B spec mode and leave for a few hours I come back to my system off. Is there a power save or sleep mode on the PS3 that shuts it off? I'm usually back before the 4 hours is up so whats going on?
Just to add, you can't change it while your in a game, you have to change it before you load anything up. All system changes can only be done outside of a game.
It's under settings, look for sleep settings and change that. On the PS3.
