     Yes, that's what I expected.

     Quite understandable, no point spending too much time on something   
   you're not going to use.   
      
     It would be interesting to see if sleep (manual or timed) works on   
   your system and if so, which parts of the system are (not) powered down,   
   i.e. when sleeping, is the monitor off/blank? are the disks not   
   spinning? is the fan not spinning?, etc.. Normally only the power supply   
   should be up a bit, in order to maintain the content of the RAM.
