How To Fix A Broken MacBook Keyboard Backlight

how to fix broken macbook keyboard backlight

The keyboard backlight you find on MacBooks is a great feature, especially for those who enjoy working late into the night. Equally, when it breaks, it becomes a big pain point for many people. You always have the option of having it repaired at the Genius Bar, assuming your computer is still under warranty, but if not then you may find yourself running up a costly repair bill. In this article, we explore several options for repairing a broken MacBook keyboard backlight.

While on the newer versions of the MacBook (2016 onwards) this issue isn't as prevalent, if you're still rocking an older machine, don't worry, MacInfo has got you covered.

Identifying The Issue

The first thing to do is understand if your MacBook keyboard backlight is actually broken, or just malfunctioning. To check if your MacBook keyboard backlight works, hold down the following key combo:

fn + F6

This will turn your keyboard backlight up to the max setting. If it still fails to turn on, or you notice the keyboard backlight is dim or flickering, you may have an issue. Another option is to completely reboot your computer and try the above key combo.

Also, you will want to ensure that the ambient light sensor on your MacBook is not blocked and is functioning correctly. This sensor is responsible for triggering the MacBook's keyboard backlight. When it senses too much light, it turns off the backlight and when it doesn't sense enough, it turns it on.

You can test this by covering it up with your finger which should trigger the keyboard backlight, or by shining a flashlight into it which should turn off the keyboard backlight. The light sensor is located on the top bezel of the screen, as shown below:

If this still does not work, try the following potential solutions.

Software Solutions

We want to start with the easiest and least costly methods - software solutions. The first thing we can do, to attempt to reset the MacBook keyboard backlight, is to perform an SMC Reset.

SMC stands for System Management Controller and is a central piece of software on all MacBooks that allows you to reset certain parts of your system to their default settings. To do this, ensure that your MacBook is turned off completely and your charging cable is unplugged. Then, perform the following key combo:

Shift + Control + Option, then press the power button at the same time

Then wait for your MacBook to complete the booting process. Once it is fully powered up, attempt to turn the keyboard backlight brightness all the way up with:

fn + F6

Hardware Solutions

If the previous options still have not solved your problem, you may need to replace your keyboard backlight. Luckily, these are quite affordable (generally in the range of $30) and easy to install yourself with simple instructions and a screwdriver.

This is a great alternative to paying an Apple technician to replace it, as they typically bill over $100 to replace them and it can take several days or even weeks. You can purchase a new keyboard and backlight combo for your appropriate MacBook model below. If it isn't listed, try this search at Amazon.

Hi, my name is Mike and I made this site to document all the helpful tips and tricks that I've discovered using various Apple Macs and other Apple products over the years, as well as to provide more general guides in relation to using the internet. I've been obsessed with Apple products ever since I could afford my first iPod, and am somewhat of a fanboy (you might have guessed). For me, the simply work without any fuss, issues or errors. I can rely on their products. The build quality is excellent and I even have several, several-year-old Macbooks in my wardrobe that are still humming along fine (just a bit slower). You can contact me personally using the form on this page.

  1. I found this article just in time. My MacBook Air 2015 keyboard backlight hasn’t been working for a couple of weeks and has been driving me nuts. I was going to get Apple to fix it which is expensive but then I learn I can easily do it myself! I’ve bought the replacement you suggest and it should be here tomorrow. Such a great price, too.

  2. I can vouch for the Padarsey replacements. My keyboard backlight was not working for some time and this was the solution I came across. I thought it might be difficult but no, it was actually really easy to fix and now I have a working backlight again! Just be careful to choose the correct one for your MacBook, they all look the same.

  3. Good to know there are options to fix it myself! My MacBook keyboard backlight is definitely failing and I can’t afford a new MacBook right now. The software solution didn’t work for me unfortunately so it looks like I’m buying a replacement keyboard. Does anyone know if these keys feel the same to type on as the default keys?
