To turn on the backlight for your keyboard, you can typically use the function keys on your keyboard. On newer Surface devices, the F5 key cycles through four levels of backlighting. If you have an older model, you may need to use the F7 key. Additionally, ensure that the Fn key is toggled correctly if your keyboard requires it for function keys to work properly.
If these methods do not work, check your device settings to ensure that the keyboard backlight feature is enabled.
