I think in the OP's case these are the same - I think (and he'll have to 
clarify) that he just wanted the screen to turn off when he closed the 
lid, right before it goes to sleep, and have the screen come on when he 
opens the lid.  Sounds like S1 is working fine for him otherwise (which 
I do believe to be true for D600's).

Yea, that's what I do - I just shut the lcd off too to save power, but I 
don't go into any S* modes (because they don't work).
