Keyboard backlight of my HUAWEI laptop does not turn on

Problem

The computer's keyboard backlight does not turn on.

Cause

The backlight may be turned off by mistake.

Solution

1. Restart your computer, and check whether the keyboard backlight turns on for two to three seconds and then turns off during power-on. If the backlight does not turn on after your computer is powered on, take your computer and proof of purchase to an authorized Huawei Customer Service Center for assistance.
2. If the keyboard backlight turns on for 2 to 3 seconds during power-on, it indicates that the keyboard backlight functions normally. You can press F3 () on the keyboard to turn on or off the backlight and adjust the backlight brightness.
   

   By default, the keyboard backlight automatically turns off when the keyboard has been idle for 15 seconds, and the keyboard backlight brightness is restored to the previous value when you operate the keyboard again. If you need to change the backlight duration, see Turning on or off the keyboard backlight and setting the backlight timeout on my HUAWEI laptop.

3. If the backlight cannot be turned on or adjusted by pressing F3, you may have enabled Prioritize functions. In this case, press Fn on the keyboard to turn on the indicator on the key, then press F3 to turn on or off and adjust the backlight. For details about how to set Prioritize functions, see Method 2 in How to use hotkeys on HUAWEI computers.
4. If the issue persists, back up your data and take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance.
