I have read on the forums about issues with other laptops and being unable to activate/turn on the backlit function on their models (all the JW or other models). I recently purchased an ASUS G73S laptop from a vendor in CA (Excalibur I believe). When I started up the computer, the backlight worked fine on the keyboard but the ASUS auto update utility started doing its thing and when the computer restarted, the keys would light up on boot but will not function during operation. I have tried cycling through the three buttons at the top left but none of the "Fn+" buttons work. Please help! I also notice when logging on that I get a series of messages that state "Must run on an ASUS machine" and "Can not load KTB kernel" or something to that affect. Thank you.
