In today’s digital world, using a laptop at night or in low-light environments can be challenging without proper keyboard lighting. That’s where a backlit keyboard comes in handy. It not only enhances visibility but also gives your laptop a stylish appearance. If you’re wondering how to turn on light on laptop keyboard, this guide will walk you through everything — from checking support, turning it on, troubleshooting, and adjusting brightness to brand-specific solutions.
1. Introduction
Most modern laptops now feature backlit keyboards that illuminate keys for better typing visibility in dim environments. This feature is especially helpful for students, gamers, and professionals who often work at night.
However, not every laptop supports keyboard backlighting. That’s why understanding how to identify, activate, and customize it is essential. Learning how to turn on light on laptop keyboard can save you time, improve typing comfort, and even extend your device’s usability in dark settings.
2. Check if Your Laptop Supports a Backlit Keyboard
Before trying to enable keyboard lighting, confirm if your device includes this feature. Some laptops come with basic keyboards without backlighting. You can verify support through several methods:
- Look for a Keyboard Backlight Icon — Most backlit laptops have a light or bulb symbol printed on one of the function keys (F1–F12) or on the spacebar.
- Check Laptop Specifications — Visit your manufacturer’s official website and search your laptop model number.
- Read the User Manual — The manual usually specifies whether your keyboard includes backlighting.
- Observe in a Dark Room — When you press the suspected key combination, a faint glow should appear under your keys if your keyboard supports lighting.
| Brand | Typical Key for Backlight | Backlight Symbol Location |
|---|---|---|
| HP | F5, F4, or F11 | Top function keys |
| Dell | F10 or F6 | Function key row |
| Lenovo | Spacebar | Bottom middle |
| ASUS | F7 or F4 | Function key row |
| Acer | F8 or F9 | Function key row |
If your laptop doesn’t have these icons or the keys don’t respond, it may not include a backlit keyboard.
3. Standard Methods to Turn On Keyboard Backlight
Now that you’ve confirmed your laptop supports keyboard illumination, let’s discuss the standard methods to turn on light on laptop keyboard. Most laptops use simple function key combinations.
3.1 Using the Function (Fn) Key
Press and hold the Fn key (usually at the bottom-left corner) and tap the key that has the light symbol — for example, Fn + F5 or Fn + F10.
Some laptops have brightness levels, so pressing this combination multiple times may cycle through Low → Medium → High → Off lighting.
3.2 Using Fn + Spacebar
Certain brands like Lenovo use the Fn + Spacebar shortcut to toggle the keyboard light on and off. You may see three stages: off, dim, and bright.
3.3 Dedicated Keyboard Backlight Key
High-end or gaming laptops sometimes feature a separate key solely for controlling the backlight. It’s usually placed above the numeric pad or near the power button.
3.4 Through Manufacturer Software
Gaming or premium laptops often allow lighting control through brand-specific software like ASUS Armoury Crate, HP OMEN Command Center, or MSI Dragon Center. These tools provide brightness, color, and effect customization.
3.5 BIOS or Firmware Settings
If your function keys aren’t working, you can enable or disable the keyboard backlight feature in the BIOS settings. Restart your laptop and press F2, F10, or DEL to enter BIOS, then locate the “Keyboard Illumination” setting.
