Used option 2 to enable the time option. Its no longer grey'ed out but setting it doesn't do anything.
I set the time to 1 minute, waited 90 seconds, nothing happened, then set to 2 minutes, waited 150 seconds, nothing happened.
Removed the powersave password prompt in regedit - no change. Powersave options don't trigger anything, dimming screen, putting it to sleep. I can manually put it to sleep with the Func F3 (sleep key), manually lock it with CTRL-ALT-DEL Enter. But can't get it to auto lock or sleep.
