It may be a simple on/off or, on some models, you can adjust the brightness of the backlighting. Simply clicking this button while pressing the Fn button located at the bottom row of your keyboard will leave you with keyboard lighting operational magic. I hope you can help me, thank you in advance for your attention. This button may even be labeled with a backlight icon. What bothers me is that the lighting does not activate before logging in because I do not see the letters and it annoys me that I have already updated drivers and look for the ASUS ATK version 61 that by the way the Asus support no longer has it, and continue with the same problem.
after another couple of minutes they settle down.
It turns out that now it does not light up and only after logging in with my user and waiting a few minutes does it light up and with errors (example: I have rainbow lighting applied that changes from left to right and when the error gives me the keyboard is totally badly illuminated (that is, keys with colors that have nothing to do with the theme, keys off, do not move and some with colors with high brightness and others with very low brightness). Hello, it turns out that when I turn on the laptop in the beginning it would type an animation and the keyboard would light up completely red after that it would go to the configuration that I had chosen for lighting.
