7 Tools To Manually Turn Off Notebook or Laptop LCD Screen

Whenever I stop using my laptop but I decide to leave it turned on while on the battery, I’ll make sure that I turn off the LCD screen. The main reason I turn the screen off is I think that it’s pretty logical that doing so will save at least some power and prolong the charge in the battery. Even if the laptop is plugged in, saving a tiny amount of electricity and also possibly leaving the laptop slightly cooler all help in their own small way.

The Power Options in Windows have a setting to turn off the monitor after xx amount of minutes when your computer is idle. While this works, setting it to kick in too fast can be annoying because you don’t want the screen to go off when in the middle of reading something. The best option is to manually turn off the laptop’s LCD screen as and when you want to.

Some laptops have a shortcut F key combined with the Fn key to turn the LCD screen off and then by pressing any key will turn it back on. Unfortunately not every laptop has a basic button or combination key that can be used to manually turn off the LCD screen. It’s also entirely possible that your keyboard has issues and the Fn key is not working and there is no way to replicate that key other than changing the whole keyboard which could cost big money.

There maybe times when you just want to leave your laptop for a few minutes but don’t want to put it to sleep because it might be doing something like downloading a file from the internet. Similarly, you might be listening to an audio book or some music while on your travels. If you can’t turn the screen off manually using any keyboard function shortcuts to save a bit of power, here’s a selection of simple and easy ways that you can use to manually turn off your laptop’s LCD screen on command.

1. Turn Off LCD

This simple little tool was developed by Taimur Asad to turn off the LCD screen on the HP notebook he owns because it lacks a basic button to switch off the display whenever he wants to. The author decided to make his own small application which turns off his notebook LCD just with one click. The application is written in C# using Microsoft Visual Studio 2008.

The program is very small, only 85KB is size and no installation is required. All you need to do is just run executable file “Turn Off LCD.exe” whenever you want to turn off your LCD screen. To turn on the screen, simply hit any key on your keyboard or move your touch pad/mouse. The .NET Framework v2 or higher is required.

2. Monitor Off Utility

Monitor Off Utility takes the simple double click to turn off the screen idea a bit further and gives you some extra configuration options on how and when you want to do it. You can create a hotkey for turning off the screen and also another one for switching on the screensaver.

In addition there are also options to enable the Windows Lock Screen before the screen goes into standby and a delay countdown which will popup on the screen and give you a countdown of time to the screen turning off. If you just want it to behave like the Turn Off LCD program you can do that too and change the options to turn off the screen on launching the program and also when double clicking the tray icon. Do be careful when setting up a hotkey because you could easily configure it accidentally to conflict with a system hotkey such as print, copy or paste etc.

For the hotkeys to work the program needs to be running in the system tray which has a context menu for screen turning off, locking or enabling the screensaver. Monitor Off has some command line options for use in scripts, shortcuts and batch files, the list can be found in the Help menu. The .NET v2 is required and it runs on Windows 98 and above, portable or installer versions are available.

3. Monitor Energy Saver (MonitorES)

The Monitor Energy Saver program comes in two flavors; the first and most basic “Lite” version is a plain and simple portable tool of under 30K that you launch and it will sit in the tray consuming under 500KB of memory. When you want to turn off your screen, press the hotkey combination of Ctrl+F2 or the system Lock Screen keys of Win Key+L which will lock and then turn the screen off.

The standard version has more advanced configuration options and useful features such as setting your instant messenger client to Away and pausing the running media player while the screen is off, and re-enable them when the screen turns back on again. The media players supported include iTunes, WinAmp, Windows Media Player, AIMP, Media Player Classic and several more. The messaging programs supported are Google Talk, Yahoo Messenger, Miranda and Digsby.

You can also set a custom hotkey for both turning the display off and enabling the screensaver along with a custom away message for the messenger program, and the extra option of muting the system volume. Both versions are completely portable and less than 50K each.

4. Sleeper

Sleeper is another basic tool by TheFreeWindows that will perform the simple task of putting your desktop monitor or laptop screen into its low power state by shutting it off. Sleeper is almost identical to Turn Off LCD above apart from being a bit larger file size (790KB) and you simply double click the executable to turn the screen off. TheFreeWindows also have another program called NumPad Transformer which adds several shortcuts to your NumPad keys, one of which is the option to put the screen to sleep. This does actually use the Sleeper standalone utility to do it.

5. Monitor Off

Monitor Off is along the same lines as Sleeper and you simply double click the executable to turn off the display. The program is a tiny 40KB file and it will also honor the security settings so if you usually resume from a screensaver or standby to the lock screen, that will also happen after turning the screen on after using Monitor Off.

6. BlackTop

The way BlackTop works is again very simple any easy, and it will sit in the system tray waiting for you to need to put the screen into a low power state. Then all you have to do is press the program hotkey combination of Ctrl+Alt+B and it will immediately put the screen to sleep. Press ant key or move the mouse/touchpad to bring the screen back to life.

7. NirCmd

Another tool that is able to turn off your LCD screen and much more besides is by NirSoft. NirCmd is really a little Swiss army knife utility In addition to turning off the display, it can also perform other tasks such as ejecting optical drives, altering the system volume, a number of window and process related functions, clipboard functions and also log off, standby and screensaver options.

NirCmd is a command line only utility and requires you to create a shortcut which you can then add the command to switch the display off.

1. Download the tool and extract the zip file. Copy it to the location of your choice, or double click the NirCmd.exe and there is a button you can click which will copy it to C:\Windows for you (Vista and 7 users will need to right click and “Run as Administrator” if you’re not the Administrator).


2. Right click on your Desktop -> New -> Shortcut.

3. Click the button to browse and locate the NirCmd.exe and press OK. If you let it copy itself over to the Windows folder, just enter nircmd.exe into the box.

4. After nircmd.exe in the text box, enter ” monitor off” (including space but without quotes).

5. Give the shortcut a name such as Turn Off My LCD Screen. Click Finish.

You can right click the new shortcut -> Properties -> Change Icon to find a more appropriate icon.


Obviously, you can use any of NirCmd’s other functions by following the same procedure to create a shortcut. We also use the NirCmd tool to turn off the display using a keyboard hotkey, and it works well. Check out the website for a complete list of other functions.

Download NirCmd

There is another little utility along the same lines as NirCmd which can turn off the display that we have used in the past called Wizmo. It’s not been updated for several years and we’ve never used it on Vista or 7, but there’s no reason why it wouldn’t work. It does have a few functions NirCmd doesn’t so is worth a look.
