** edit -- your service tag provides the answer.  Your keyboard is not backlit:

580-ADZD: Non-backlight keyboard (Japanese) 86
556-BBCD: Mo

Is this a case where you have a system you've never tried the backlight, or that it has worked in the past, but no longer does?  If it's the former, are you certain the system has a backlit keyboard (which would have been optional -- not standard when the system was built;  regardless of that, the setting in setup would be there)?

If it's a case that the backlight has worked in the past, does it illuminate briefly during the power on self test?  If it does not, it's a hardware issue -- check the connection between the backlight cable and mainboard inside the system.
