Currently, the keyboard performs not only its functional role, but also a stylistic one, emphasizing the individuality of each user. One of the most popular ways to highlight the style of a particular device is to provide a bright and unusual backlight. Its presence provides not only an individual style, but also has practical value. It allows you to ensure comfortable use of this gadget even in the dark. However, in some cases, its presence can be annoying, especially in situations where the light does not turn off automatically when the computer is turned off. We will tell you how to do it yourself.
Disable in the keyboard settings
In order to turn off the annoying light, there are several basic ways.
Using a special button
Often, especially on premium devices, there are special buttons that are responsible for controlling the backlight. Usually they are located on top or on the side of the gadget case. These buttons are responsible not only for turning on or off the backlight itself, but also for its brightness or color gamut, as well as the intensity of radiation (on some models).
Using a special application
For many devices there are special applications which allow you to make settings for brightness and color. They also allow you to set the sensitivity and reassign keys on the keyboard.
