Bluetooth keyboard (KT-1255) "function lock" not working with X1 Yoga 3rd Gen

When using X1 Yoga 3rd Gen, with external Bluetooth keyboard (KT-1255), "function lock" feature does not work.  Pressing Fn + Esc does not toggle function keys between “special function” and their F1-F12 application functions.  I cannot find a way to get the function keys to operate in the mode of the native program (e.g. in Microsoft Word, F5 is "go to page") unless I hold the Fn key every time I want to use the function keys.


I have:

1. Updated all drivers for PC and Bluetooth keyboard

2. Set Lenovo Vantage keyboard setting so that this is set to be on: "The top row of keyboard provides: F1-F12 function" (see attached file).


X1 Yoga Model Number 20JF000DUS

Processor: Intel(R) Core(TM) i7-8650U CPU @ 1.90GHz 2.11 GHz

Installed RAM:  16.0 GB (15.8 GB usable)

Bluetooth Keyboard Model: KT-1255

What's DOS?

I also have this problem. I am running a T480s and the bluetooth keyboard's function lock does not work.
I have also reinstalled the driver from the Lenovo site to no avail.
Bluetooth keyboard model: KT-1255
Does anyone have a solution for this? It is a very annoying problem and it really reduces the utility of the keyboard...
