How to fix a keyboard backlight that doesn’t work on Windows and Mac

All MacBook Pro and Air laptops now come with a backlit keyboard that not only makes typing easier in low light but also looks very stylish. Since the backlight uses very low-power LEDs, it has little effect on battery life when the brightness is set at a reasonable or low level. This is why many people prefer to have a backlit keyboard at all times, even if the lighting situation doesn’t require it to be useful.

But sometimes, for no apparent reason, a backlit Mac laptop keyboard won’t work at all and even trying to manually control the backlight with the keyboard shortcuts tells you that the feature isn’t working or is disabled.

There are several possible reasons why the backlight may stop working on your MacBook Pro, MacBook, or MacBook Air, most of which offer simple solutions. If you find that the backlight on your MacBook Air or MacBook Pro keyboard is not working, follow these troubleshooting steps. In most cases, you can resolve the situation quickly and easily.
