The backlights never work, no matter what I do, but everything else works fine
Any tips are much appreciated

Have you tried EC reset? Unplug the AC and shutdown the laptop > long press the power button for over 25 seconds > plug in the AC and power on again
Also try pressing FN+F8 to adjust the keyboard backlight.
