this is indeed a weird behavior. If you depend that much on the backlight i would go like this routine:
Try to make a hard-reset including completely disconnceting the unit from the power source (including the battery).
A less mechanical thing would be to try to reset the bios (did you update it recently?) and see if it works again.
Last idea, no matter how "ridiculous" it might be - maybe you can "reset" your physical connection on the motherboard - like - if there is a connector - disconnect - reconnect it. Still - a very deep dive mechanical "solution", though.
After that still not having any success, i would get in contact with Dell and ask for a solution.

Hope that helps a little.

I had a similar problem. I updated my bios and my backlight on my keys was fixed, thanks for the tips!
