No problem, I'm an electronic technician so this kind of stuff is right down my alley. The other cool thing this functionality lets you do is go into windows power options and set it to shut down windows when you press the button. It does the same thing as going though the start menu and selecting Shut Down, a gracefull shutdown. My spare PC is in my bedroom. I often listen to music with the monitor turned off. When I'm done I just press the power button on the case and turn off the speakers. Its a lot easier than turning on the monitor, grabbing the mouse, etc, etc.
