How to Turn On Keyboard Light on Asus ExpertBook Easily

Enabling the keyboard backlight on your Asus ExpertBook can greatly improve visibility in low-light environments, making typing easier and more comfortable. This feature is especially useful during nighttime work sessions or in dimly lit rooms. Before you begin, ensure your laptop model supports keyboard backlighting, as not all Asus ExpertBook variants include this feature.

What You’ll Need

• An Asus ExpertBook laptop with a backlit keyboard feature
• Functional keyboard and operating system running (Windows 10 or later recommended)

Step-by-Step

1. Locate the Keyboard Backlight Key: On most Asus ExpertBook models, the keyboard backlight is controlled using the Fn (Function) key in combination with one of the function keys (usually F3 or F4). Look for a key with a symbol resembling a keyboard or light rays.
2. Press the Key Combination: Hold down the Fn key located at the bottom left of your keyboard, then press the backlight key (e.g., F3 or F4) to toggle the keyboard light on or adjust brightness levels.
3. Cycle Through Brightness Levels: Many ExpertBook models offer multiple brightness levels. Pressing the backlight key repeatedly while holding Fn will cycle through off, low, medium, and high brightness.
4. Check Keyboard Lighting: Observe the keys to confirm the backlight has turned on. If the keyboard lights up, the process was successful.
5. Adjust via Asus Software (Optional): Some ExpertBook models include Asus software utilities like “Asus Keyboard Hotkeys” or “Armoury Crate” where you can customize backlight settings. Open the software and navigate to keyboard lighting options for more control.
6. Update Drivers (If Needed): If the keyboard backlight does not respond, ensure your keyboard and chipset drivers are up to date. Visit the Asus support website, enter your ExpertBook model number, and download the latest drivers.
7. Check BIOS Settings: In rare cases, the keyboard backlight may be disabled in BIOS. Restart your laptop, enter the BIOS/UEFI by pressing F2 or Del during boot, then look for keyboard lighting options and enable them if necessary.

Common Mistakes

• Pressing the wrong function key: Not all Asus ExpertBook models use the same key for backlight control. Verify your specific model’s key.
• Not holding the Fn key: The backlight toggle typically requires holding Fn while pressing the backlight key.
• Assuming all ExpertBooks have backlit keyboards: Some budget or entry-level models do not include this feature.
• Ignoring software and driver updates: Outdated drivers or missing Asus utilities can prevent keyboard lighting from working.
• Forgetting to check BIOS settings: Keyboard backlight can sometimes be disabled at a firmware level.

Tips

• Use the Asus Armoury Crate app: If your ExpertBook supports it, Armoury Crate offers more precise control over keyboard lighting effects and brightness.
• Adjust keyboard brightness to save battery: Lower brightness settings consume less power, extending battery life.
• Consult your user manual: Your ExpertBook’s manual will specify exact keys and software for controlling the keyboard backlight.
• Customize lighting shortcuts: Some Asus laptops allow remapping of function keys through software for easier access.
• Keep your laptop’s firmware updated: Firmware updates can improve hardware compatibility, including keyboard lighting.

Troubleshooting

If the keyboard backlight does not turn on as expected, try the following troubleshooting steps:

• Confirm your model supports keyboard backlight: Check Asus’s official website or your laptop’s specifications.
• Verify the correct key combination: Look for keyboard icons on the function keys or consult the manual.
• Restart your laptop: Sometimes a reboot resolves temporary software glitches affecting hardware controls.
• Update keyboard and chipset drivers: Go to Asus’s support page, download, and install the latest drivers for your ExpertBook model.
• Check BIOS settings: Restart and enter BIOS to ensure keyboard backlight is enabled.
• Disable conflicting software: Some third-party keyboard utilities may interfere with Asus’s backlight controls.
• Perform a system restore: If the backlight recently stopped working after an update, restore to a previous system state.
• Contact Asus support: If none of the above resolve the issue, hardware failure may be involved, and professional assistance is advised.
