Many modern laptops and some desktop keyboards come equipped with backlighting, a feature that illuminates the keys, making typing in low-light conditions significantly easier and more comfortable. However, figuring out how to activate this feature can sometimes be a puzzle. This comprehensive guide will walk you through various methods for turning on your keyboard light, covering different brands, models, and potential troubleshooting steps.
Understanding Keyboard Backlighting
Keyboard backlighting isn’t just a cosmetic feature; it’s a practical tool. Whether you’re working late into the night, gaming in a dimly lit room, or simply prefer the aesthetic, knowing how to control your keyboard’s illumination is essential. Let’s explore the common ways to switch it on.
Identifying Backlit Keyboards
Before diving into the activation methods, it’s crucial to confirm that your keyboard actually has backlighting. Look closely at the keys, especially the function keys (F1 through F12). Keyboards with backlighting often have a symbol on one of these keys representing illumination. This symbol might be a sun-like icon, a keyboard outline with radiating light, or the letter “A” with radiating light. If you see such a symbol, your keyboard likely has backlighting capabilities. You can also check the manufacturer’s specifications for your laptop or keyboard model online.
Common Methods for Turning on Keyboard Backlighting
The most common method involves using the function keys in combination with the “Fn” key. However, the specific key combination can vary depending on the manufacturer and model. Let’s examine some of the most popular brands and their corresponding methods.

Why isn’t my keyboard light turning on, even after pressing the designated key?
Several reasons can cause this issue. First, confirm that your computer model actually has a backlit keyboard. Some models within a specific brand or series might not include this feature. Consult your computer’s manual or the manufacturer’s website to verify if keyboard backlighting is supported. If supported, ensure the appropriate driver is installed and up-to-date. Outdated or corrupt drivers can prevent the keyboard light from functioning correctly.
Secondly, check your power settings. Many laptops automatically disable keyboard backlighting to conserve battery life. Access your power management settings within your operating system and verify that the backlight is not disabled or set to a low brightness level when running on battery power. Additionally, some manufacturers include a setting within their proprietary software to control keyboard backlighting, so be sure to check that as well.
How do I identify the correct key to turn on my keyboard light?
The key to activate keyboard backlighting varies depending on the laptop manufacturer and model. Typically, it’s a function key (F1-F12) combined with the “Fn” key. Look for a key with a symbol resembling a light bulb, a sun, or a keyboard icon. If you are unable to locate the key, refer to your laptop’s user manual.
If the symbol is unclear or you still can’t find the correct key, try searching online for your specific laptop model and “keyboard backlight” or “keyboard light shortcut”. Online forums and support pages often provide model-specific instructions. Experiment by pressing the “Fn” key along with each of the function keys individually to see if any of them activate the light.
Is it possible to change the color of my keyboard backlight?
Changing the color of your keyboard backlight depends entirely on whether your laptop model supports this feature. Most standard laptops only offer a white backlight, while gaming laptops often feature customizable RGB (Red, Green, Blue) backlighting. If your laptop has RGB backlighting, you’ll need to use the manufacturer’s software to adjust the color.
This software is usually pre-installed on your computer, but if not, you can download it from the manufacturer’s website. The software will allow you to select different colors, create lighting effects, and customize the backlight for individual keys or zones. If you cannot find color settings within the software, your keyboard likely only supports a single color.
My keyboard light is very dim. How can I make it brighter?
Increasing the brightness of your keyboard backlight is usually done through the same method as turning it on: the function key combined with the “Fn” key. Often, there will be two keys with similar symbols, one to increase the brightness and one to decrease it. Press the “Fn” key along with the brightness-up key repeatedly to cycle through the brightness levels.
If this method doesn’t work, check your laptop’s power management settings. Some power plans may limit the maximum brightness of the keyboard backlight to conserve battery power. Also, look for a setting within the manufacturer’s proprietary software that controls keyboard backlighting. Some applications allow for fine-grained control over brightness levels.
Can I disable the keyboard light completely?
Yes, you can usually disable the keyboard light entirely. The process is typically the reverse of turning it on. Use the “Fn” key combination with the key that controls keyboard backlighting, typically the one with the light bulb or sun symbol. Pressing the key repeatedly will cycle through the different brightness levels, eventually turning the light off completely.
Another way to disable the keyboard light is through your laptop’s power management settings. Many laptops have options to automatically turn off the keyboard backlight after a period of inactivity or when running on battery power. Look for these settings within your power plan configurations. These settings are often found in the advanced power settings.
My keyboard light flickers or is inconsistent. What could be the cause?
A flickering or inconsistent keyboard light can indicate a few potential problems. It could be a driver issue. Try updating or reinstalling the keyboard drivers to ensure they are functioning correctly. Outdated or corrupt drivers can cause erratic behavior with hardware features like backlighting. This is especially true after OS updates.
Another possibility is a hardware problem. The LED lights themselves might be failing, or there could be an issue with the power supply to the keyboard. In this case, it is best to contact the manufacturer or a qualified technician for repair. Attempting to repair the keyboard yourself could void your warranty or cause further damage.
Does an external keyboard also have a backlight?
Whether an external keyboard has a backlight depends on the specific model. Many gaming keyboards and higher-end ergonomic keyboards feature backlighting, while more basic models typically do not. Check the product specifications or features list when purchasing an external keyboard to confirm if it includes a backlight.
If your external keyboard has a backlight, it will usually be controlled by dedicated keys or a software application provided by the manufacturer. The keys are usually located near the top of the keyboard, or as part of the function key row. Refer to the keyboard’s user manual for specific instructions on how to turn on, adjust, and customize the backlight.
