Keyboard backlight does not work.
Performed a complete system re-install using HP tools; factory reset for this model. Downloaded tool from HP, used USB drive.
Windows Version 10.0.17134 Build 17134
All Windows Updates are up-to-date
Upgraded the BIOS
Ran the HP hardware diagnostic for the keyboard, all keys passed.
Went into BIOS, disabled "action keys", tried Fn + F5; re-enabled "action keys", tried just "F5"; nothing turns on the lights.

Turn on or off the backlight
If your notebook computer has a backlit keyboard, press the F5 key on the keyboard to turn the light on or off. It might be necessary to press the Fn (function) key at the same time.
If the backlight icon is not on the F5 key, look for the backlit keyboard key on the row of function keys.
If you still have issues, continue troubleshooting.
Re-install the keyboard driver
1) In Windows, search for and open Device Manager.
2) Double-click Keyboards.
3) Right click on the keyboard drivers and click on uninstall.
4) Restart the computer.
Also, try running the updates.
