I have a T440p which came with a non backlit keyboard, which I wanted to replace it with a backlit one. After installing the new keyboard the backlight wouldn't come on (i'm using Fn + spacebar, the keyboard has the light icon on the spacebar and the OS shows an icon for the backlight).
I tried swapping it out with a friend's keyboard (from a t450s which was replaced due to a damaged key) but without any luck.
Could this be an issue with the motherboard or controller? What are my options?
I appologise if I have overlooked a topic describing this issue, but all of the topics related to the keyboard backlight were related to the fact that the keyboard wasn't backlit while the user was expecting it to be.

I'm dual booting linux and WIN10, and it doesn't work in both. Turning it on in Lenovo settings doesn't either.
I have found this page https://support.lenovo.com/fr/en/solutions/ht104656 which states that it's a hardware feature and should be driver independent. I tried turning it on while in BIOS as well.
