How to Turn Keyboard Light Back On Asus Laptop Easily

Reactivating the keyboard backlight on your Asus laptop can greatly improve your typing experience in low-light environments. Whether your keyboard light has turned off unexpectedly or you simply want to adjust its brightness, this guide will walk you through the steps to turn it back on. No special tools are required, just your Asus laptop and a few minutes of time.

What You’ll Need

  • An Asus laptop with a backlit keyboard feature
  • Basic familiarity with your laptop’s keyboard and function keys
  • Windows operating system (most Asus laptops run Windows)

Step-by-Step

  1. Locate the Keyboard Backlight Key: On most Asus laptops, the keyboard backlight is controlled by a function key, usually marked with a keyboard icon or a light symbol. Common keys include F3, F4, or sometimes F7, F9. These keys often have a small light icon.
  2. Use the Function (Fn) Key: To toggle the keyboard light, press and hold the Fn key (usually found near the bottom-left corner of the keyboard) and then press the keyboard backlight key identified in the previous step. For example, Fn + F3 to decrease brightness or turn off, and Fn + F4 to increase brightness or turn on.
  3. Cycle Through Brightness Levels: Some Asus laptops support multiple brightness levels for the keyboard backlight. Press Fn + the backlight key repeatedly to cycle through off, low, medium, and high brightness settings until the light turns on.
  4. Check the Asus Keyboard Hotkeys Software: Asus laptops often come with pre-installed software like Asus Keyboard Hotkeys or Armoury Crate. Open this software from the Start menu or system tray to adjust keyboard lighting preferences if the function keys don’t work.
  5. Verify the Keyboard Backlight Settings in BIOS: Restart your laptop and enter the BIOS/UEFI settings by pressing F2 or Del during boot-up. Navigate to the Advanced or Device Configuration tab and ensure that the keyboard backlight option is enabled. Save changes and exit.
  6. Update Keyboard and System Drivers: Visit the Asus support website, enter your laptop model, and download the latest keyboard and chipset drivers. Installing these can resolve software-related issues preventing the keyboard backlight from turning on.
  7. Restart Your Laptop: Sometimes a simple reboot can restore the keyboard light function, especially after software or driver updates.

Common Mistakes

  • Pressing the Backlight Key Without Fn: On many Asus models, the backlight key requires the Fn key to activate. Pressing it alone may not work.
  • Ignoring BIOS Settings: Some users forget to check if the backlight feature is disabled in BIOS, which can prevent it from turning on.
  • Assuming All Asus Models Use the Same Keys: Keyboard backlight keys vary between models. Using the wrong function key or shortcut will not work.
  • Overlooking Power Settings: Certain power-saving modes can disable keyboard lighting. Not checking power profiles can cause confusion.
  • Not Updating Drivers: Outdated or missing drivers can cause hardware features like keyboard backlighting to malfunction.

Tips

  • Refer to Your Laptop Manual: If you’re unsure which keys control the backlight, check the user manual or Asus support site for your exact model.
  • Use Armoury Crate for Advanced Controls: Asus’s Armoury Crate software offers advanced lighting customization and troubleshooting options.
  • Adjust Brightness Based on Environment: If the keyboard light is too bright or too dim, cycle through brightness levels to find a comfortable setting.
  • Keep Your Laptop Updated: Regularly update your Windows OS and Asus drivers to prevent compatibility issues affecting keyboard lighting.
  • Check for Physical Damage: If the keyboard light never turns on, inspect your laptop for any keyboard damage or liquid spills that might have affected the backlight.

Troubleshooting

If the keyboard backlight does not turn on after following the steps above, try these troubleshooting methods:

  • Confirm Your Laptop Has a Backlit Keyboard: Not all Asus laptop models include keyboard backlighting. Verify your model’s specifications on Asus’s official website.
  • Test in Safe Mode: Boot your laptop into Safe Mode to determine if third-party software is interfering with the keyboard light. If it works in Safe Mode, uninstall recently added applications.
  • Reset BIOS to Default: Sometimes BIOS settings can cause issues. Enter BIOS and reset to default settings, then check the keyboard light again.
  • Check Windows Mobility Center: Open Windows Mobility Center (press Windows + X and select it) and look for keyboard backlight controls if available.
  • Run Asus Diagnostic Tools: Use any built-in Asus diagnostic software to test hardware components including the keyboard backlight.
  • Perform a System Restore: If the backlight recently stopped working, restore your system to a previous point when it was functional.
  • Contact Asus Support: If none of the above fixes work, hardware failure may be the cause. Reach out to Asus technical support or visit a certified repair center.
