I have my laptop set to turn off the screen after 10 minutes, but what if I am in a hotel room in the middle of the night and I want the screen to go dark immediately. Is there any way to do that without opening the power applet or installing a utility? The Win+L hotkey will lock the screen. Is there another hot key to make it go blank or can I configure Win+L to go blank much sooner (10 seconds?)?
