I bought a second hand T14s Gen 2, and as my norm, wiped it out and proceeded to do a clean install of Windows (10, in this case).
After installing the drivers listed for my specific machine at Lenovo's site, there was still one Unknown Device. A web-search did not reveal info specifically for LEN0130, so I did a recovery.
After the recovery, it didn't take me very long to find the right device, since I figured that it would ben named "Lenovo ..." In System Devices, it appears as Fn and Function Keys.
Now that I knew what to look for, I found the appropriate driver in T14s Gen 1's list of downloads. It is currently at:
https://pcsupport.lenovo.com/us/en/prod ... t-thinkpad
Go figure why it isn't listed for Gen 2. Perhaps Gen 2 already has this version out of factory, so it's not listed because it isn't an update. Grr.
Hope this helps someone
