Hmmm problem is that the sort of setup we are working with isn't really designed to be slept or even turned off/on a regular intervals. The issues arise when you are doing so without 1st shutting down the running apps (SAB/CP/SB)... because they run as processes and do all their work in the background if your not careful you can try and sleep/turn off the machine while SAB is unpacking files/moving files or CP/SB are doing database updates, while most of the time it won't cause too many problems you may find corruptions appearing.
I think your best bet is to try and quieten the machine down instead, I'm sure there is info on the net from people that have already done it. I have mine attached to my TV at the base of my bed and tbh I don't even notice it anymore except it something finishes downloading as I'm half asleep and notice a drive spinup.... doesn't happen often
