The keyboard backlight does not work, is a common problem that can occur under Windows or Mac. But if you encounter this problem, you can take a look at this message. This article will give you a complete solution and explanation of keyboard lighting that does not work on Windows and Mac.
When you connect, you will hear a bing-like sound after bootcamp.exe starts, and the keyboard LEDs will light up. Sometimes Windows is updated and the lights may not work.
Use the Task Manager
If you don’t see the lights, go to the Task Manager and search for bootcamp.exe. If it is a custom CPU field > 0%, a character is easily found by right-clicking on the bootcamp icon in the taskbar, it slows down to open a popup, you simply exit the bootcamp.exe process. Then try restarting it and wait until the CPU field is at 0%.
Mac & Light sensor adjustment
In some situations, direct light, bright lights, sunlight or glare may shine directly on the light sensor of the MacBook Pro or MacBook Air, and when this happens, the display and light controls lock.
The solution is simple: adjust your Mac so that the light source no longer shines on the screen and close to the forward-facing camera. This is a function, not an error, to automatically turn off the backlight when it is not needed and would not be visible anyway, such as using a MacBook outdoors in the sun.

Restart your computer
In general, restarting your computer can solve many common problems. Turn off your computer and remove the battery. After a few seconds, reinsert the battery and restart your computer. Then check if the backlight on the Windows 10 keyboard does not work or not. If this method does not work, try another one.
Keyboard care tips
1. Try not to eat, smoke or drink on the keyboard to keep it clean.
2. Do not hit the keyboard hard over and over again. This will damage the soft glue that supports the keyboard keys.
3. Clean the keyboard regularly. Dust accumulates in the space and causes the keyboard to malfunction if you have not cleaned it for a long time.
