Hello,
I have a Microsoft surface laptop 7, and the keyboard backlight button does not work.
The button to increase and decrease brightness works, the F5 key works with Fn enabled (which the kb backlight is set to.)
The lights for CapsLock and Fn respectively both work but nothing happens when I hit the F5 key.
I never changed any settings and I believe it never worked from when I got the laptop but I cannot remember. Does anyone know of a setting I can look at or drivers for me to install to get this working, I cant see the keyboard in the dark! Thanks.

Shutdown Surface
Press Vol + Power on to move to UEFI screen.
If the backlight works here, then it's a driver related issue.
If not. then it's a hardware related issue and download and run Surface diagnostic tool from MS Store.
