So, pressing the Fn + F6/F10/arrow keys simultaneously should enable keyboard lights on Dell laptops. If it does not work, you need to find the backlit key for your keyboard to control the keyboard lights.

Before we jump into the how-to part of the question, you need to know whether your laptop’s keyboard has a backlight.

Not all Dell laptops have a backlit keyboard. To check whether your keyboard has backlights, search the function keys for the backlit key. Usually, a key with a backlit icon, shown in the image, is the key that controls the keyboard backlight.
