Hello guys. I have Helios 500 for 6 months now, but lately i observed strange colour change on keyboard backlight. Im pretty positive, that at the beginning, makro keys, touchpad and keyboard back light were all the same colour but now keyboard itself is more green compared to makro keys and touchpad. It's like a cannot set default blue on keyboard, its either darker or lighter but something wrong is happening with this colour. Does this mean keyboard is damaged or something? Anyone has similar problem?
