The backlit keys interface seems to be broken, so you need to mask the controlling service: systemctl mask systemd-backlight@leds\:dell\:\:kbd_backlight.service
then go to BIOS and and change the keyboard led timeout from 10s to 5s for AC Power and Battery mode - "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."
In the void is virtue, and no evil. Wisdom has existence, principle has existence, The Way has existence, spirit is nothingness.
