Is your MacBook Air 2019 keyboard light refusing to shine? Don't panic! It's a common issue with usually simple fixes. First, check your ambient light sensor – it's near the webcam. If the room is bright, the keyboard light will automatically dim or turn off to conserve battery. Try covering the sensor briefly to see if the light activates.
Next, adjust the keyboard brightness manually. Press the F5 key (decrease brightness) and F6 key (increase brightness). Make sure you haven't accidentally turned it all the way down. Also, check your System Preferences. Go to Keyboard and ensure 'Adjust keyboard brightness in low light' is ticked, and the slider isn't set to the lowest setting. A quick restart can also work wonders. If none of these steps work, it could be a hardware issue, and it's best to contact Apple Support for further assistance. Good luck getting your glow back!
