Checking the function key
When the light on your laptop keyboard is not turning on, one of the first steps you should take is to check the function key dedicated to controlling the keyboard backlight. Most laptops have a dedicated function key or combination of keys that allow you to toggle the keyboard backlight on or off. Here’s how to do it:
1. Look for the function key with the icon resembling a keyboard or light bulb. It is usually labeled with “Fn” or “Fn Lock” and is typically located on the bottom left or right corner of the keyboard.
2. Press and hold the “Fn” key and then press the corresponding function key with the keyboard or light bulb icon. On some laptops, it may be a standalone key like F6 or F7, while on others, it may be combined with other keys, such as the F5 key.
3. Check if the keyboard backlight turns on or off after pressing the function key combination. Sometimes, the keyboard backlight has multiple brightness levels, so pressing the combination multiple times may cycle through different brightness settings.
If the keyboard backlight still doesn’t turn on after checking the function key, don’t worry. There are other methods you can try to resolve the issue. It’s important to follow these troubleshooting steps to narrow down the potential causes and find the appropriate solution for your laptop’s specific model.
Adjusting the brightness settings
If the keyboard backlight on your laptop is not turning on, it could be due to incorrect brightness settings. Here’s how you can adjust the brightness settings to enable the keyboard backlight:
1. Locate the brightness control keys on your laptop’s keyboard. These are usually identified by symbols resembling a sun or light bulb, which are often located on the top row of the keyboard.
2. Look for the function key labeled “Fn” or “Fn Lock” on your keyboard and press and hold it.
3. While holding the “Fn” key, press the brightness control key to increase or decrease the brightness level of the keyboard backlight. Typically, the brightness control keys have arrows pointing up and down, indicating the increase or decrease of brightness respectively.
4. Observe the keyboard backlight to see if the brightness level changes as you press the brightness control keys. Repeat the process until you find a suitable brightness level for your preference.
If adjusting the brightness settings doesn’t fix the issue, there may be other factors causing the problem. Continue to the next section to explore alternative solutions.

5. Disconnect external keyboards: If you’re using an external keyboard, disconnect it from your laptop. Sometimes external keyboards can interfere with the built-in keyboard backlight functionality.
6. Reset BIOS settings: Access the BIOS settings by pressing a specific key during startup (usually Del, F1, or F2). Look for options related to the keyboard backlight and make sure they are enabled.
If none of these troubleshooting steps resolve the issue, it is recommended to consult the manufacturer’s support or seek professional assistance to further diagnose and resolve the problem.
Ensuring the keyboard backlight is enabled in the BIOS settings
The BIOS (Basic Input/Output System) settings on your laptop control various hardware functionalities, including the keyboard backlight. If the keyboard backlight is not turning on, it’s essential to check if it is enabled in the BIOS settings. Here’s how you can do it:
1. Restart your laptop and continuously press the designated key to access the BIOS settings during startup. The key to enter the BIOS can vary depending on the laptop manufacturer (commonly Del, F1, or F2).
2. Once you’re in the BIOS settings, navigate through the menu using the arrow keys on your keyboard. Look for an option related to the keyboard backlight. It may be located in the “Advanced” or “System Configuration” section.
3. Enter the submenu and ensure that the option for enabling the keyboard backlight is turned on. If it’s already on, you can try toggling it off and then back on again.
4. Save the changes made in the BIOS settings by pressing the designated key (usually F10) and exit the BIOS setup.
5. Allow your laptop to boot up and check if the keyboard backlight turns on after the changes have been applied.
Enabling the keyboard backlight in the BIOS settings ensures that the hardware is configured to support the functionality. If the keyboard backlight still doesn’t work after enabling it in the BIOS settings, there may be other underlying issues that require further troubleshooting or professional assistance.
Cleaning the keyboard to improve light visibility
If the keyboard backlight on your laptop is dim or not as visible as before, it could be due to dirt, dust, or debris accumulated on the keyboard surface. Cleaning the keyboard can help improve light visibility and restore its functionality. Follow these steps to clean your laptop keyboard:
1. Shut down your laptop and disconnect it from the power source to prevent any accidents or damage.
2. Use compressed air or a small handheld vacuum to remove loose debris from the keyboard. Hold the can of compressed air in an upright position and gently blow air in between the keys to dislodge any dirt or dust.
3. Take a soft, lint-free cloth or keyboard cleaning brush and lightly dampen it with a small amount of isopropyl alcohol or a gentle cleaning solution. Ensure the cloth or brush is not dripping wet, as excess moisture can damage the keyboard.
4. Gently wipe the keys and keyboard surface using the damp cloth or brush. Pay close attention to the areas around the keys where debris often accumulates. Clean in a circular motion or gently slide the cloth between the keys to remove any hidden dirt.
5. If there are stubborn stains or sticky residue, dip a cotton swab in isopropyl alcohol and carefully clean the affected areas.
6. Allow the keyboard to air dry completely before turning on your laptop. It is essential to ensure that no moisture is left on the keyboard to avoid electrical damage.
Cleaning the keyboard can improve the visibility of the backlight by removing any obstructions caused by dirt or debris. If the keyboard backlight is still not working properly after cleaning, there may be other hardware or software-related issues that require further investigation or professional assistance.
