Using hotkeys
Progressive users are well aware of the usefulness, and in some cases the need for hotkeys. At a minimum, in this situation, this is the easiest answer to the question of how to turn off the brightness on a laptop of absolutely any model.
First of all, find the Fn key. It is located at the bottom left, next to the Win button. Remember, since the keyboard on laptops is oftensmaller than on a PC, and all the keys do not fit on it. In addition, there are additional functions on laptops, which is why the Fn key is needed. If you hold it down, some buttons change their purpose. Now you will understand everything with a good example.

So, you hold down Fn, now find the key on which the sun is drawn. There are always two of them side by side, to decrease and increase the brightness. Often they are placed on the top panel, where a row of numbers with the prefix F (F1, F2, F3 …) is installed. While holding Fn, press the sun icon and the brightness will increase or decrease, depending on which key you press.
Now you know how to turn off the brightness on your laptop.
