My T450 always turns on keyboard backlight when I power-on the machine or even just wake it up from sleeping. I don't look at the keyboard at all, so I don't need this backlight; but worse, it just uselessly consumes some power from battery (I do work without AC quite often), and I might miss the fact that the backlight is on for hours of working on battery, that's pretty annoying.
Is that intended behavior? Can this "feature" be turned off? I don't see any option in BIOS for that.
