I have tried almost everything - this AU question is the last option.

I have set-up Ubuntu through a subsystem on Windows 10 to perform this. I just need the right guidance for success. I tried an old thread on which I had no success, it was this thread.

How can I turn off the backlighting of my Sony VAIO Laptop?

Reset to default

I belive the following should do it, I found this solution to enable it for me (with a 1 instead of the 0). A reboot will be required too.

$ echo "options sony-laptop kbd_backlight=0" > /etc/modprobe.d/sony-laptop.conf
