Does the keyboard light ever come on? You can try covering the light sensor with your thumb to see if it will turn the backlit keyboard on. The sensor is located at the top of the LCD bezel, to the left of the camera lens. If the keyboard still will not come on, you can try holding the FN key, and repeatedly pressing the letter i on the keyboard, to increase the backlight brightness.

If the light still will not come on, it could be a hardware issue that requires service.
