Turn off laptop screen immediately

by mtnjmcd / September 3, 2012 12:10 PM PDT

The laptop with be an HP Windows 7 machine. The screen brightness can be turned down with F keys but not off unless making adjustments in Control Panel.

Is there any software to install that will allow a hotkey for example, to be used to immediately blacken the screen? Apple's laptops have a button that will dim the screen until it's black by pressing it several times.

Thank you.

Keep in mind this is not a Windows feature.

On some HP's you can tap the FnKey to switch from internal to external displays and cause the effect you want.

Not a Windows feature?!

Thank you Bob. I had no idea. Now to convince myself to buy an HP laptop again...I recall that you had some issues as well. Problem is that I need a Windows machine for work. Maybe just add Fusion or Parallels to the MacBook Pro...

Fn Key
by mtnjmcd / September 3, 2012 12:37 PM PDT

Thinking about this a bit more after doing a Google search. Does the Fn key by itself darken the screen or is it used combined with another key?

An alternative is to instantly minimize the open window/tabs. Is there a quick way to do that?

Thanks Bob (or anyone else).

FnKeys are
by R. Proffitt Forum moderator / September 3, 2012 12:42 PM PDT
In reply to: Fn Key

Combination keys where you press the Fn button then tap another button. I do not see you supply a link to a product manual so I'll stick with simple generic answers. Try the FnKey that switches from internal to external displays. Since there is no external the effect is the internal screen off you asked for.

Works on may laptops. But you are seeing more and more folk that don't want to know their machines. Can't blame them.

Imagine folk's surprise long ago
by R. Proffitt Forum moderator / September 3, 2012 12:44 PM PDT

When audio was not a Windows feature. Fast forward to today and you find many versions don't work with all features of today's PCs. It's an interesting issue and why some folk are left in the dark at times.

How about this route ...
by Edward ODaniel / September 5, 2012 8:59 AM PDT

or this

or these

or even create a shortcut and assign a keyboard shortcut to a black screensaver, use this path:

%systemroot%\system32\scrnsave.scr /s

This will not turn off you screen but makes it completely black

And of course as Bob noted most laptops have an function key that paired with the Fn key (generally Fn + F7 but that can differ between manufacturer's) simply switches to an external monitor or rotates between laptop, external, and both.

And now you have choices.

Windows + P
by t_morgan / December 22, 2015 6:47 AM PST

Windows + P should give you the option for Projector only, which causes the Laptop display to lose the signal and then go to sleep thus saving power. You would leave the Laptop lid open just enough to access the power button.

I use this trick to make use of old Laptops for the elderly who generally prefer a big monitor and real keyboard.
