- Backlit keyboards are keyboards with keys that are backlit by an LED.
- They provide better visibility and make typing easier, even in completely dark rooms.
- But sometimes, for no apparent reason, a backlit Mac laptop keyboard won’t work at all.
- There are several possible reasons why the backlight may stop working on your MacBook Pro, MacBook, or MacBook Air.
In addition to making typing easier in low light, the backlit keyboard on all MacBook Pro and Air laptops looks very stylish as well. When the brightness is set at a reasonable or low level, the backlight uses very low-power LEDs, so it has little effect on battery life. Due to this, many people prefer to keep a backlit keyboard handy even when there is not enough lighting to make it useful.
When running BootCamp running Windows 10, my MacBook Pro’s backlit keyboard does not work (i.e. there is no lighting).
There are times, however, when Mac laptops with backlit keyboards suddenly stop working completely and even its keyboard shortcuts won’t let you manually control the backlight.
Keyboard Lit Up
On certain MacBook models, the Increase brightness key looks like half a sun with three rays, so you can turn on the backlighting. You can adjust the brightness of the keyboard light by pressing it until it is as bright as you want. Press the Decrease brightness button until the light turns off, which appears as a half-circle outlined with dots.
Most of the time, you can fix the problem with your MacBook Air, MacBook Pro, or MacBook Air backlight after it stops working for several reasons. Follow these troubleshooting steps if you notice the backlight on your MacBook Air or MacBook Pro keyboard isn’t working. The problem can usually be solved easily and quickly.
What causes the backlighting of Windows and Mac keyboards to fail?
Backlit keyboards make typing in completely dark rooms easier by providing better visibility and making it easier to see the keys. Both laptops and desktop computers now come with backlit keyboards.
Several factors can influence the performance of the backlit keyboard.
There can be a problem with the software or hardware if the update was not done correctly.
What do I do if my keyboard backlight isn’t working on my Mac?
Until you reach your desired level of backlight, press the key several times.
Verify the position of your light sensor
The first thing to look for is that the sensor is pointed directly at the source of light.
You may not be able to use the automatic backlight in this case.
Make sure the Ambient Light Sensor is positioned properly. Then, check whether the Mac keyboard backlight is working.
Adjusting the brightness of your keyboard
Using these steps to adjust the keyboard brightness may also fix the backlighting problem if you set it to 0.
- At the top left of the screen, click the Apple icon.
- To change your system preferences, click System Preferences…
- From the list of choices, select Keyboard.
- Check the box “Adjust keyboard brightness in low light conditions.” and uncheck it.
- Changing the brightness of your keyboard can be done manually by pressing F1 or F2.
Modify the entire keyboard
You may need to replace a keyboard in this case if you spill liquid on it, such as water, milk, or soup. The keyboard backlight may stop working if you spill liquid on it. The Mac keyboard can either be replaced yourself or sent to a Mac repair service. The latter option is highly recommended.
In the event that the keyboard backlight does not work after installing the latest Windows Update, you may need to uninstall it. Otherwise, you may be able to restore your computer to a previous state if you created a System Restore Point in advance.
Normally, you would have to purchase a suitable new keyboard bezel. You also need to prepare tools such as screws, knives, screwdrivers, and others. Once your Mac is turned off, you will need to remove the battery for the keyboard bezel to be replaced.
Contact customer service
Your Mac’s customer service is the best place to turn if all these methods fail to fix your backlit keyboard.
In this way, you will be able to reach the target directly and effectively.

Restart your computer
