Q: How to turn the keyboard backlight on or off?
A: The keyboard backlight can be enabled by pressing the Fn + Space key combination. The keyboard backlight is turned on by default and stays on, and the brightness is divided into two levels. Therefore, assuming that the keyboard light is in the off state, pressing the key combination three times in sequence means the keyboard light is weak, the keyboard light is intense, and the keyboard light is off.
Notice: The backlight of the keyboard will consume power, so it is recommended to turn it off during the day.
