Keyboard light not working

• On many ASUS laptops, the keyboard backlight can be toggled on or off using a specific key combination, usually involving the Fn key and one of the function keys (like F7, F3, or F4, depending on the model).
• Try pressing Fn + F7 (or the key with the backlight icon) to see if the backlight turns on.

• Some models allow you to adjust the brightness level of the keyboard backlight. If the backlight is set to the lowest level, it might appear off.
• Use the Fn key in combination with the brightness adjustment keys to increase the brightness.

• ASUS laptops often come with pre-installed software like ASUS Keyboard Hotkeys or ATK Package that manages special functions, including the keyboard backlight.
• Make sure this software is installed and up-to-date. You can check for updates on the ASUS support website for your specific model.

• Ensure that your keyboard and chipset drivers are up-to-date. Outdated drivers can sometimes cause issues with hardware functionality.
• Go to the ASUS support website and download the latest drivers for your model.

• Sometimes, the keyboard backlight can be disabled in the BIOS/UEFI settings. To check this:
  1. Restart your laptop and enter the BIOS/UEFI setup (usually by pressing F2, Delete, or another key depending on your model).
  2. Look for settings related to the keyboard backlight and ensure it is enabled.

• Occasionally, performing a hard reset can resolve hardware-related issues.
  1. Power off your laptop.
  2. Disconnect the power adapter and remove the battery (if it's removable).
  3. Press and hold the power button for about 30 seconds.
  4. Reconnect the power adapter and battery, then power on the laptop.

• If none of the above steps work, there might be a hardware issue with the backlight itself. This could involve a loose connection or a faulty component.
• In this case, you might need to contact ASUS support or take the laptop to a certified repair center.

By following these steps, you should be able to identify whether the issue is software-related or if it might require professional repair.
