As with your "earlier question", I assume this is still about the keyboard backlight (not the computer). Set the brightness all the way down to zero to--effectively--turn off the backlight. There's no ambient light brightness sensor (as with a smartphone display) that I'm aware of for the keyboard backlight. (And to correct my earlier estimate from my first answer since we can't edit our answers here: the backlight "timeout to off" is about 30 seconds (not "a minute or so" as I guesstimated before).)
Sorry, there was a problem. Please try again later.You can turn the computer off completely, yes. But you can not set your Chromebook to only turn on when it's dark.
