Although, in fact, everything is quite simple. There are two ways to do this:

- by using function keys
— through software configuration tools

You can use it Let's look at both methods in detail.

1. Brightness keys

Due to the fact that laptops have great requirements for compactness, they try not to have extra buttons on it. Here they took a different route - the developers combined a number of keys to make them functional. Usually icons additional functions printed in a different color (blue or orange). The brightness adjustment keys on the laptop are marked in the shape of a sun:

Previously, they removed it from a couple of buttons in the row F1....F12, but Lately Together with the volume, they began to be transferred to the “arrows”:

To use them and reduce or increase the brightness of the laptop or netbook screen, you need to press the button Fn, which is located next to Ctrl, and, holding it, click on the desired function.

By the way, if these keys do not respond to pressing, this means that Windows installation OSD drivers were not installed. They can be downloaded from the mobile computer manufacturer's website.

2. Software brightness adjustment

If for some reason you cannot adjust the screen brightness on your laptop using the keyboard buttons, then you can do this programmatically, through the parameters of the power supply scheme used. To do this, right-click on the Start button and in the menu that appears, select “Power Management”:

If suddenly you don’t have this item in the menu, then select “Control Panel”:

In the Panel menu that appears Windows controls Find the “Power Options” icon and click on it:

It is worth noting that on some laptops (for example, HP) the brightness adjustment was displayed as a separate slider right in the window for selecting the device’s power scheme:

Don’t forget about one more “trick” of Windows 8 and Windows 10 - this is the Mobility Center, which allows you to configure many laptop parameters in one window at once. To get into it, you need to right-click on the battery icon to bring up the context menu:

In it you need to select the “Windows Mobility Center” item. The following window will appear:

Besides standard tools For driving laptop computer, built into Windows OS, there are also third party utilities directly from the manufacturer, which are part of the pre-installed software. As a rule, such software is added to startup by default and its icon hangs in the system tray, next to the clock. For example, in Lenovo IBM ThinkPad it is Power Manager.

Among its many options, there is also the ability to increase or decrease the screen brightness - the Monitor Brightness parameter.

Note:

1) IN software, included with the video adapter driver ( AMD Radeon Control Center, NVidia Control Center, Intel Graphics Control Panel, etc.) there are also tools for adjusting monitor parameters.

2) In Windows 8 and Windows 10, you can force the laptop to independently change the brightness of the display depending on the light level (of course, if its hardware supports this feature). To do this, you need to go to the additional parameters of the active power supply scheme:

Find the “Screen” section and expand it. Among available parameters find the line “Enable adaptive adjustment brightness" and below set the parameter to "On". Click on the “Apply” button.
