By the end, you’ll know exactly how to activate backlit keyboard settings on your device — without guessing.
Let’s start by understanding what a backlit keyboard actually is — and how to check if your laptop even supports it.
What Is a Backlit Keyboard?
A backlit keyboard is a keyboard with lights underneath the keys. These lights make the letters visible in low light or dark rooms.

Steps:
Some laptops don’t require the Fn key — try pressing the key alone if needed.

When This Option Appears
You’ll see a “Keyboard Backlighting” section only if your laptop supports backlighting, or the manufacturer has enabled Mobility Center support.
If available, you can:
If you don’t see a keyboard backlight option here, your laptop likely controls it through BIOS or manufacturer software instead.
Method 3: From BIOS / UEFI Settings
If shortcuts and Mobility Center don’t work, the feature may be disabled in BIOS.
How to Access BIOS:
You’ll enter the BIOS/UEFI setup screen.
Where to Find Keyboard Backlight Settings
Inside BIOS, look under sections like:
Search for options such as Keyboard Illumination, Keyboard Backlight, or Backlight Timeout.
Enable it or adjust brightness/time settings.
Save & Exit
After enabling the setting:

To check or enable this:
Enable the automatic adjustment option if available.
You can also choose how long the keyboard light stays on after inactivity.

How to Enable Keyboard Light on Gaming Laptops (RGB Models)
Gaming laptops are a different beast.
