If you’ve ever tried using your laptop in a dim room, on a late-night flight, or during an evening work session, you’ve probably wished your keyboard keys were easier to see. That’s where a keyboard backlight comes in. A keyboard backlight illuminates the keys from underneath, making typing much more comfortable in low-light environments.
Many modern Windows laptops include this feature, but not every model does. One of the most common questions users ask is, “How do I know if my Windows laptop supports a keyboard backlight feature?” The good news is that there are several easy ways to find out. You do not need advanced technical knowledge, and most checks can be completed in just a few minutes.
In this guide, you’ll learn how to identify whether your Windows laptop has a backlit keyboard, where to find the necessary settings, and what to do if the feature appears to be missing.
How Do I Know If My Windows Laptop Supports the Keyboard Backlight Feature?

To determine whether your Windows laptop supports a keyboard backlight feature, look for a keyboard backlight icon on the function keys, check your laptop’s specifications, review keyboard settings in Windows, access the BIOS or UEFI settings, or use the manufacturer’s support software. If none of these methods show a backlight option, your laptop likely does not include a backlit keyboard.
The following steps will help you determine whether your Windows laptop supports a keyboard backlight.
1: Look for the Keyboard Backlight Symbol on Function Keys
The easiest place to start is your keyboard itself. Most laptop manufacturers place a keyboard illumination icon on one of the function keys.
Carefully examine the keys in the top row of your keyboard. Look for symbols that resemble a glowing keyboard, a light shining over a keyboard, or small rays of light around keys. These icons are commonly found on keys such as F3, F4, F5, F7, F9, F10, or F12, depending on the manufacturer.
If you see this symbol, your laptop likely supports a backlit keyboard. In many cases, pressing Fn + the corresponding function key will turn the keyboard light on or off. Some laptops also allow multiple brightness levels, meaning you can cycle through dim, medium, bright, and off settings.
Even if the lighting does not activate immediately, the presence of the icon is a strong indication that your keyboard was designed with backlighting support.
2: Check Your Laptop’s Official Specifications
If you cannot find a backlight symbol on the keyboard, the next step is to verify your laptop’s specifications.
Start by identifying your laptop’s exact model number. You can do this by typing System Information into the Windows Search box and opening the application. The model number will appear under the System Model field.
Once you know the model number, review the product specifications provided by the manufacturer. Look for features such as Backlit Keyboard, Keyboard Backlight, Illuminated Keyboard, or White LED Keyboard.
This method is particularly useful because many laptop families include multiple configurations. For example, one version may include a backlit keyboard while another version may not. Checking the exact specifications helps eliminate guesswork.
If the specifications clearly mention a backlit keyboard, then your laptop supports the feature even if it is currently disabled.
3: Check Windows Keyboard Settings
Many manufacturers provide keyboard lighting controls through Windows settings or companion software.
Open the Settings app and navigate through available device customization options. Depending on your laptop brand, keyboard lighting controls may appear under device settings, personalization settings, or manufacturer-specific utilities.
For example, gaming laptops often include dedicated applications that manage lighting effects, brightness levels, and timeout settings. Business laptops may offer simpler controls that allow users to enable or disable keyboard illumination.
If you find settings related to keyboard brightness, keyboard illumination, or backlight timeout, this confirms that your laptop includes a backlit keyboard.
Even if the lights are currently turned off, the presence of these settings indicates that the hardware supports the feature.
4: Open the BIOS or UEFI Settings
The BIOS or UEFI firmware often contains hardware-level controls that are not visible within Windows.
Restart your laptop and enter the BIOS setup screen. The key used to access BIOS varies by manufacturer, but common options include F2, Delete, Esc, or F10.
Once inside the BIOS, look for sections related to Keyboard Settings, Advanced Settings, or Device Configuration.
Many laptops with backlit keyboards include options such as:
- Keyboard Backlight
- Keyboard Illumination
- Backlight Brightness
- Backlight Timeout
If any of these options appear, your laptop definitely supports keyboard lighting.
This method is especially useful when the lighting controls are not visible inside Windows due to missing software or driver issues.
5: Use Your Manufacturer’s Support Software
Most major laptop brands provide management software that allows users to control hardware features.
For example, manufacturers often include utilities that manage battery settings, performance modes, cooling systems, and keyboard lighting.
Open any support or device management application that came preinstalled with your laptop. Browse through the available settings and look for keyboard-related controls.
If you find options for keyboard brightness, lighting effects, illumination zones, or backlight behavior, then your system supports a keyboard backlight.
Many users discover that their keyboard light was simply disabled within the manufacturer’s utility rather than missing altogether.
6: Test the Common Keyboard Backlight Shortcuts
Another simple way to verify support is to test the most common keyboard backlight shortcuts.
Press the Fn key together with the function key that contains a keyboard lighting symbol. If you are unsure which key controls the feature, carefully test the top-row function keys one at a time.
Watch the keyboard closely while performing the test in a dimly lit room. Some keyboards illuminate immediately, while others display a notification on the screen showing the current brightness level.
If the keyboard lights up after using a shortcut, you have successfully confirmed that your laptop supports the feature.
7: Inspect the Keyboard Hardware Physically
If all other methods fail, perform a visual inspection of the keyboard.
Move to a dark room and shine a flashlight across the keyboard surface. Backlit keyboards typically have translucent characters that allow light to pass through the keys. Non-backlit keyboards usually have solid keycaps without visible lighting components underneath.
You can also examine the spaces around the keys. Backlit keyboards often reveal subtle gaps where illumination shines through when activated.
Although this method is less reliable than checking specifications, it can provide additional clues about whether the hardware was designed with lighting support.
Additional Tips
If your keyboard backlight suddenly stops working, update your keyboard drivers and manufacturer software before assuming there is a hardware problem.
Keep your laptop plugged into power when testing the feature. Some laptops automatically disable keyboard lighting during battery-saving modes.
Check whether your laptop includes automatic ambient light detection. Certain premium models turn the keyboard light on only when the surrounding environment becomes dark.
Make sure the Fn Lock setting is configured correctly, as an incorrect function key mode can prevent keyboard shortcuts from working as expected.
If your laptop originally included a backlit keyboard and the lighting no longer works, installing the latest BIOS update may resolve the issue.
