Keyboard Backlight Auto-Dimming

I have an Inspiron 15 7559 running windows 10 with a backlit keyboard. Whenever I don't touch the keys for 1 minute, the backlight goes to sleep, and turns back on once I touch it again. This annoys me, because in the dark I have to guess which key I want, wait a second, and then correct it if it was wrong.

I've searched for a way to stop this in my computer's settings for the keyboard and powersaving options, but have been unable to find anything. I would like to be able to make the backlight never dim itself, if possible. Thank you very much!
