Hello, bharat prajapati1
Welcome to the Microsoft Community.
Hello, if your computer keyboard supports backlighting, to turn on the keyboard light in Windows 11, you can follow these general steps:
- Find the "Fn" key on your keyboard. This key is usually near the bottom left corner of the keyboard.
- Find the key with the keyboard light icon. This key is usually one of the function keys (F1, F2, etc.) and may have an icon that looks like a keyboard or light.
- Press and hold the "Fn" key and then press the key with the keyboard light icon. This should activate the keyboard light on your laptop.
In addition, some brands of computers are turned on by pressing win+spacebar. You may need to consult your computer manufacturer for specific operations. You can also provide the model here and I will check it for you.
