Backlight problem

[Preethi35]

I can't find any icon in f4 and f5 key. I want to turn on my backlight. Some are saying use space+fn but it's not working in my system. So how to turn on backlight

Check here:

Open User Guide

Go to Pages 10-11

If your F5 key lacks (does not have) the control icon for the keyboard back light, your computer does not have a back lit keyboard.

The option is available on "select products only" (when the computer is purchased).

Find / Check for parts at PartSurfer / HP Parts Store
