I'm have my VAIO hooked up to a big ViewSonic monitor, and often don't use the screen on the laptop, so would like to know if there's a way to toggle the laptop screen on and off. Just trying to save a little energy and keep the computer cooler. I'm looking for something that does more than just dim the screen the way the F5 and F6 keys do.
The model is a VPCEF34FX running Windows 7 Home. Thanks.
