Most HP laptops use a simple key combination to control the backlight. Here’s how to turn on lights on an HP keyboard: Locate the backlight key, usually F5, F9, or F11, marked with a keyboard illumination icon. Press the Fn (Function) key along with the backlight key. On some models, the right arrow key may control the backlight.

Press the “Fn” key and the backlight key (F5, F4, or F11) simultaneously. This combination usually toggles the keyboard light on or off. If pressing it once doesn’t work, try pressing it a few times, as some models offer different brightness levels.

How do I turn the backlight on or off? On most notebooks with a backlit keyboard, you can press the f5 or f4 key on the keyboard to turn the light on or off. It might be necessary to press the fn key at the same time. If the backlight icon is not on the f5 key or f4 key, look for the backlit keyboard key on the row of function keys.

Your laptop model might need to be charged a certain amount to turn on the keyboard backlight. Press the keyboard backlight key to increase the brightness. You might need to press and hold the Fn key while pressing the backlight key. If your backlight won’t turn on or stay on, change the “Action Keys Mode” or timeout setting in BIOS.
