    F3 And F4 Not Working On Windows 10 Laptop


    So, my Function 3 and Function 4 keys aren't working , which are meant to light up the keyboard on the laptop , but for some reason I cannot get them to work.


    The lights last worked like 3 weeks ago and I don't think the lights are dead!


    Anyone had the same problem? I need help here.

    Some fn+fkey (f3,f4, etc.) don't work

    Hello. Ever since I changed to Windows 10, I lost the ability to use some fn shortcuts. I can no longer use fn+f3, f4, f9 and I also can't use the NVidia key, nor the Steam key. I have an Asus ROG G751jy gaming laptop.

    fn+f3 = dim keyboard backlight

    fn+f4 = brighten keyboard backlight

    fn+f9 = toggle touchpad

    Change what Fn + f3 and Fn + f4 do

    At the first time I use my new laptop ( ASUS A455LA, Win. 10), the Fn+f3 and Fn+f4 combination is empty (no command to do). One day, I press Fn+f3 and the computer ask me what kind of command to do, I choose to open Google Chrome.
    The problem is, I accidentally choose the same thing to do with fn+f4 (also to open Google Chrome) and I want to change it like Fn+f4 = open Windows Media Player. Is it possible to do? How?

    Thank you.
