If you own a Dell laptop with a backlit keyboard feature, you might encounter instances where the keyboard backlight doesn’t work as expected. In this comprehensive guide, we’ll walk you through two methods to not only turn on and off the keyboard backlight but also fix any issues you might face. Whether you’re an experienced tech enthusiast or a beginner, these methods will help you navigate through the process smoothly.

Method 1: Using Keyboard Shortcuts

Step 1: Locate the Backlight Key

Start by identifying the key on your laptop keyboard that corresponds to the keyboard illumination icon. Typically, this icon is found on the F5 key or another function key.

Step 2: Enable the Backlight

  1. Press and hold the Function (Fn) key.
  2. Simultaneously, press the key with the illumination icon (in this case, F5).
  3. The keyboard backlight should now turn on in dim mode.

Step 3: Adjust Brightness

  1. If the dim mode isn’t sufficient, press the Function (Fn) key and the illumination icon key (F5) again.
  2. The backlight brightness level will increase.
  3. Repeat this step until you reach the desired brightness level.

Step 4: Turn Off the Backlight

  1. To turn off the backlight, press the Function (Fn) key and the illumination icon key (F5) once again.

If these steps successfully enable your keyboard backlight, you’re good to go. However, if the first method doesn’t yield results, don’t worry. There’s an alternative solution.

Method 2: BIOS Settings

Step 1: Restart Your Laptop

If the keyboard backlight issue persists, try this method. Restart your laptop, and during the startup process, press the F2 key repeatedly to access the BIOS setup.

Step 2: Access BIOS Settings

  1. After pressing F2, you’ll enter the BIOS setup.
  2. Navigate to the System Configuration option in the left pane.

Step 3: Enable Keyboard Illumination

  1. In the right pane, locate the Keyboard Illumination option.
  2. By default, it might be in the Disable mode. Change it to either Dim or Bright mode.

Step 4: Set Backlight Timeout

  1. Further down, you’ll find the Keyboard Backlight Timeout option.
  2. Choose your preferred timeout setting: On Power or On Battery.

Step 5: Apply Changes and Exit

  1. Once you’ve adjusted the settings, click on Apply Changes.
  2. Confirm the changes and exit the BIOS setup.


These two methods provide comprehensive solutions to address backlit keyboard issues on Dell laptops. Whether you’re using the keyboard shortcuts or adjusting settings in the BIOS, you have the tools to control and troubleshoot the backlight functionality.
