Windows 7, Laptop DELL XPS 1330:
When just listening to music, I want to turn off my laptop display immediately. It perfectly works after the usual delay (e.g. 10 mins) set in the power management, as described in question Why doesn’t the screen turn off when playing music
What I am looking for is a shortcut / key command to directly (manually) turn off the monitor, because why should I wait for 10 mins? So I directly want to "jump" in the state entered after 10 mins.
The idea is just to save battery for the first 10 mins.
