No keyboard backlight while using Bootcamp

Hi,

Currently using a late 13' 2016 MacBook Pro Touch Bar here.

I ran into the same problem too and no matter what I do including SMC reset, downloading the latest Boot Camp and updating it the keyboard back light just refused to turn on.

Short of reinstalling a fresh copy of Windows which I am trying my best to avoid because I think it is silly to just reinstall every time a problem comes up, I fired up Windows Explorer and navigate to Program Files > Boot Camp to see what the heck is going on.

To my amazement, I saw that there was a backup copy of the Bootcamp.exe with the extension renamed to TMP and I do not know how it got there in the first place.

From the date, I saw the it was modified back in Nov 23rd last year. Which was probably the very first time I received my MacBook and had Boot Camp installed if memory served me correctly.

So I renamed the current Bootcamp.exe extension to a temp, had the other temp file renamed back to Bootcamp.exe and I restarted Windows.

Voila, the back light of the keyboard just turned on.

Hope it helps!

I had this problem and none of these fixes worked. But I did solve the issue. The solution was so silly. I don't see it mentioned here. So I will post it in case it helps anyone else. I just pressed F6 and F5 a few times and eventually it came back. Those are the keyboard dimmer buttons.

Yes, there are some Broadcom drivers installed e.g.

Broadcom 802.11ac Network Adapter

Broadcom Serial Bus Driver over UART Bus Enumerator

But there is nothing installed with Serial UART. What confuses me further is that in the section "input devices" there is "Apple SPI Keyboard", "Apple SPI Touchbar" and "Apple Touchbar". I have no problem with the Touchbar or the keyboard. Just the keyboard backlight isn't working even If I press the button for the keyboard backlight button on the Touchbar.

I tried to install again the Bootcamp Support Software but it didn't help. I also tried to remove the keyboard drivers and pick from a list of installed drivers on my machine but there are just two to choose from.

When I installed Bootcamp I used the Bootcamp Assistent on macOS to download the drivers.

So now I used the tool called "brigadier.exe". I'm using Mac model: MacBookPro13,3 with this digits 031-92174.

But now I have the exact same driver folder like I downloaded on macOS. I guess I do something wrong :/

Yes in both the Product Version is 6.1.6655.

In the Apple Software Update there is no Update available. How can I fix this backlight issue now ^^

Also when I go into the device manager and try to install a new driver for example "Apple SPI Keyboard" it says that I have the latest driver already.

Do you have an Light Sensor entry in Device Manager? Can you run the following two procedures

Reset the System Management Controller (SMC) on your Mac - Apple Support

How to reset NVRAM on your Mac - Apple Support

and check? I assume that the OS X side works properly.

I have the same issue with my Macbook Pro 2016 with Touchbar.

There is no unknown device in the Device Manager. Driver for ambient light sensor and HID Keyboard is installed.

I'm using Windows 10 and in macOS it works normal.

Yes, i did. I tried to install the Bootcamp Support Software again but it didn't work.

I don't know what to do anymore. I also had some issues with my Wifi connection at the beginning but that get fixed over the Apple Software Update.

I had to reinstall Windows on Bootcamp to solve this issue.

I was not able to solve it without a reinstall. I guess it's a driver installation problem which accured during the Bootcamp driver installation.

Just reinstall your Windows. I had to work a few hours to configure windows to my needs but it's still worth.

Hi,

I have MBP 2017 with touchbar of course. None solution described before did not help me. I found that the reason lays in Windows version (in my case). I have instaled with bootcamp WINDOWS 10 Home N 1703. It is version with limited media resources. If you upgrade your Windows version with Microsoft patch called Media Feature Pack for Windows 10 N 1703 keyboard`s light starts magically working. Solution works on regular and fresh installation done with Bootcamp method.

Thanks C.Soon - that worked for me too, I had the same issue and tried recommended solutions in this thread short of re-installing Windows - but after renaming the temp bootcamp exe the keyboard lighting works great!

In my case solution was bit easier. I figured out Bootcamp.exe was not running in the background, so I tried to run it manually (i.e. Bootcamp executable file) from C:\Program Files\Boot Camp\Bootcamp.exe

Now, all the basic functionalities are working properly (Like WiFi, Brightness, Function Keys, Volume Controller...)

I am using MacBook Pro 15' Inch Retina 2015 Mid Model.

No, there is a Standardkeyboard driver installed. Nothing Apple specific. Where I can get the right driver?

Where I can find the right Broadcom drivers because in the Bootcamp Support Software they aren't included.
