My black MB has started to turn off when I click 'sleep system'. I'm using InsomniaX, not sure if that'd make a difference?
 
Try removing InsomniaX and see what happens.

Unfortunately, this does nothing. Still powering off instead of sleeping, or i suspect more likely, sleeping but then losing the contents of the RAM or the power is interrupted somehow??
