Bought this machine about a month ago and the keyboard backlight has never worked. I've already tried updating BIOS to 211, and uninstalling and reinstalling ATK. Fn F3/F4 do nothing. Everything else sems to work.
I have the G501JW and have tried the ATK as well as the most recent BIOS still have no back light. Running Windows 10 Pro 64. Love the laptop, but this is annoying as I cannot see the keyboard except in a well lit room.
