Comment 104 for bug 1510344

Thanks for sharing the fixes everyone. I was able to get this to work too.

For the record, the fix for me was the following:

1) mask the dell::kbd_backlight.service, as described above
2) go into the bios, and change the keyboard led timeout from 10s to 5s

Note that it had to be done in that order. For some reason if the kbd_backlight service is not masked, it somehow forces the bios led timeout back to 10s, and then the keyboard led always remains lit.
