Usually you can press the Fn key + a key that has lines coming out of a white spot on one of the top keys on your keyboard. This should be able to control the levels of brightness and turn on the brightness on your keyboard.

I understand the issue you have. There is nothing to worry about. I am here to assist. To turn on the keyboard light, kindly press the FN key + then the function key that has the icon for keyboard lights, usually F10.
