TS5 and Windows Sleep

I have noticed that despite setting up the necessary windows sleep settings as I have to, my PC still won’t go to sleep if I leave it on and leave the house. I kinda suspect that this could be because of TS5, as it has worked properly when TS5 was not running. So my question would be: does TS5 somehow prevent Windows from going to sleep, even if you don’t speak or register any other PC activity? If so, is there a way to change that?
