Is your MacBook Air 2020 keyboard backlight mysteriously dimming or failing to illuminate entirely? Don't panic! It's a common issue, and often easily resolved. First, check your ambient light sensor – the keyboard light adjusts automatically. If your environment is bright, the backlight might be off. Try covering the camera to simulate darkness.
Next, look at your keyboard brightness settings. Press the F5 key (or the brightness up key if you've customized your function keys) to increase the brightness. Accidentally hitting F4 (brightness down) is a frequent culprit.
Still dark? Head to System Preferences > Keyboard and ensure "Adjust keyboard brightness in low light" is enabled. A restart can also work wonders. If these simple solutions don't do the trick, there might be a more significant hardware or software problem. Consider contacting Apple Support or visiting an authorized repair shop for diagnosis.
