Logitech Customer FAQ

You can turn on the keyboard backlight for your Logitech Slim Folio by pressing the Lightbulb Icon Key on your keyboard. This button is usually located at the top row of your keyboard. Press it once to turn on the backlight, press it again to increase the brightness, and press it a third time to turn it off. Please note that having the backlight on can reduce your keyboard's battery life. Also, some models might have an auto sleep mode to conserve battery, where the backlight goes off after a period of inactivity. It will turn back on with a key press.
