I found this at a tenforums thread. It’s for anyone who doesn’t want their display going, but wants the comp to carry on with whatever they left it doing. Specifically, it’s for if you don’t want to wait for power management to time out the screen.

%systemroot%\system32\scrnsave.scr /s

^^ You can make a shortcut out of *that*, and then pin it somewhere. Your call.

I’m not sure what the /s is for. It wasn’t explained. But it’s just a good old screensaver kicking in, to save your screen. : )
