unfortunately the keyboard backlight of my yoga 900 has stopped working and I cannot link the problem to any windows update or something. I have already checked the BIOS and Fn Keys are enabled.
Thanks in advance

So if you press and hold the Fn Key, and then tap the space bar, the keyboard backlight does not turn on?
With the Fn Key depressed, tapping the space bar should cycle the back lighting from off > bright > dim > off.
Best of luck,

That's exactly the problem.
I have run all updates including a bios update now, but it still doesn't work.
Device manager does not give any further information.
Windows Version is Windows 10 Home, Version 1703, Build 15063.540
