Some laptop users prefer to work behind large screens by connecting an external monitor to the device. In some cases, such a screen may be needed if the matrix fails (so as not to spend money on replacing it).
It's also important to know that a mobile computer display consumes a lot of battery power. If you're just using your device to listen to music, you can turn off the display to extend battery life. Let's figure out how to turn off the monitor on a laptop.
How to deactivate the display

There are several ways to turn off the laptop monitor:
- Using a keyboard shortcut.
- By configuring the power settings to turn off the display after a certain periodtime.
- Physically disconnecting the display from the laptop.
- Closing or covering the laptop lid.
- By setting the display mode in the screen settings.
The first two methods will work for you if you want to save battery power in your laptop. Three other methods are valid when connecting an external display to the device. Let's take a closer look at how to turn off the monitor on a laptop using a keyboard shortcut and in other ways.
Save your battery life

If you turned on loud music on your laptop and moved away from it, then the display does not need to consume battery power. Using the combination of the Fn key and the corresponding screen button on a laptop, you can turn off the monitor, thereby increasing the battery life. Usually, the key responsible for the display is located in the top row of auxiliary buttons F1-F12.
By the way, using a combination of buttons, you can increase and decrease the volume, brightness, and even flip the laptop screen, that is, the image on it. The latter is used more often on personal computers than on portable devices.
You can also set your laptop to turn off the display in the power options. After a certain time interval you set, the operating system can independently turn off the monitor on the laptop and send it to sleep, if necessary.
Turn off the mobile PC screen when using an additional device

If you are going to use an external monitor of a larger size and resolution, and the laptop display only distracts you, then you can:
- In the screen settings, configure the display only on the external display.
- Close the laptop lid or close it completely, after which the screen will turn off. True, in this case, the keyboard and touchpad of the laptop will not be available to you and you will have to connect additional manipulators.
If you have damaged or broken the matrix of a portable computer and now use only an external display, then experts advise disconnecting the matrix cable from the motherboard. If you do not know how to disconnect the laptop monitor physically, how to disassemble it, then we do not advise you to try to do it yourself. Contact a specialized service center. A faulty matrix can lead to failure of the entire laptop motherboard in terms of power supply.
