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.

In power management set 'do nothing' for 'on closing lid' and close you laptops lid when you are listening to music –  Shakehar Feb 7 '12 at 15:12
    
Nice hint, but this "listening music scenario" is a special use case. I am in general happy with my settings, and I do not frequently want to change them as per use case (e.g. work / home). This is why I am looking for a key command etc. for this "special scenario music". But thanks a lot for pointing this out! –  Horst Walter Feb 7 '12 at 15:16
    
@shark that would work unless OP is using the internal speakers –  Raystafarian Feb 7 '12 at 15:16
    
@Raystafarian do nothing does exactly that ,it does nothing , so your speakers would work, closing the lid usually has a mechanical switch / sensor that just powers off the screen , everything else runs as is. –  Shakehar Feb 7 '12 at 15:42

@Shark it would likely block the internal speakers, depending on where they are located. –  Rob Feb 7 '12 at 15:44

I've used Dekisoft's Monitor Off Utility successfully before on desktops, but I can't promise that it'll function properly with the built in monitor on a laptop. It's worth a try, though. You can manually cut off the displays from the system tray or set up a hotkey for it.

Thanks, Monitor Off Utility and NirCmd work. IMHO MOUtility was easier to use since it comes with a GUI for all the settings. But this is just matter of my personal taste and laziness. –  Horst Walter Feb 7 '12 at 15:53

Nirsofts NirCmd should do it for you , and there's a nifty trick for using it by HowtoGeek
