RE: Keyboard Backlight Issue on Inspiron 15 5559

Well, the F10 key, if the Fn key is set to make the F keys function keys and not F keys, will change the brightness, on a normal system.  You can also change the brightness on the Notifications Panel.

My keys also dim if I am not using the keyboard.

If neither of those work, you may have an option to change the operation in the Bios.  Since you said that doesn't work, you may need a driver or a Bios update/reset to defaults..  

Are all the Dell supplied drivers installed?

My system does not show an on screen slider for the backlight.

I do not have Quickset installed so can't test that but I have never used it.  Can we assume the backlight stopped working before that utility was involved?
