In order to solve the task, you will need to select the correct key combination on the keyboard if the additional “Fn” button does not work. You must try to push all the buttons from the top row, starting with "F1" and ending with "F12". On each additional key you can see a certain value, for example, using these switches you can adjust the sound, adjust the brightness of the screen and make other changes.

If you want to know how to turn on the keyboard backlight (Asus laptop), but it turned out that this option is not provided, do not despair. Anyone can create the necessary lighting with their own hands, of course, you will have it external, but still you can see the keys perfectly. In order to achieve a result, you will need to use one or more LEDs. Also need an output for the USB connector. You can use only one LED, but in this case, your backlight will not help to see the entire keyboard.
Finishing touch
USB power provides five volts, and accordingly you need to choose the same power and LED. Or just use a resistor. For example, if you chose an LED that needs a power of 3.5 volts, then we select it at 1.5 volts. It is important to remember one more thing. One LED may not be enough, and in this case you need to use several at once. This can be done using a parallel connection. Experts in practice tested how much of these elements can be connected to one USB output. In total, this number is 25 diodes, so if you want to connect 5, then you can safely do it. If you yourself cannot understand how to make manual illumination correctly, then you should turn to specialists who will be able to produce even internal illumination in a laptop, but such services will cost you extremely expensive. Although in practice the connection is very simple and you do not need to devote much time to developing such a function.
