How to turn on the keyboard light on an ASUS TUF gaming laptop
The quickest way to illuminate your keyboard is using the built-in keyboard shortcut. On most ASUS TUF Gaming models, the combination is Fn + F4 to increase brightness and Fn + F3 to decrease brightness or turn the backlight off. If you want to change color of aula gaming keyboard, note that this shortcut only controls brightness, not color, for color customization, you need the ASUS Armoury Crate software. To check if your laptop has a backlit keyboard, examine the function keys for a keyboard icon with rays of light; if you don’t see it, your model may not support backlighting. If you're also adjusting your setup's audio, you might need to turn down volume on asus tuf gaming monitor separately from your laptop.
Customizing the backlight with ASUS Armoury Crate
For models that support full RGB or color customization, ASUS Armoury Crate gives you advanced control over brightness, effects, and colors. To access it:
- Open the ASUS Armoury Crate application from the Start Menu or by searching for “Armoury Crate” in the Windows search bar.
- Navigate to the “Device” tab or a similar section where you can manage your laptop’s settings.
- Look for the “Keyboard” or “Lighting” option and click on it to open the keyboard lighting settings.
- Choose from a range of colors, effects, and brightness levels. You can synchronize lighting effects with other ASUS components or create custom profiles for different scenarios.
- Save your changes to apply the new settings.
Using Armoury Crate allows you to personalize the keyboard backlight beyond simple on/off control, making it ideal for gaming or work environments where you want a specific look or reactive effects.
