Fully working, with replacement power adapter, Folio Keyboard + Rugged Case. NOTE - the touchpad left & right clicks  on the folio keyboard are out of position. Everything else works.

Model - Thinkpad X12 Gen 1

Type Number - 20UV-S57F00

 i5-1130G7 (4 cores, 8 Threads)

Base frequency: 1.1Ghz

Boost frequency: 4Ghz

256 SSD

1080P

Windows 11 Pro (you will need to provide a key of your own)

The charger works normally, but it is a generic charger. ie: NOT OEM lenovo charger.

The touchpad "clicks" do not work properly (see photo).
The touchpad is slightly lifted on the left side, and sunk in the right side. Thus the left and right clicks don't work properly. Everything else about the keyboard works normally - trackpoint and it's clicks are all fine and the touch portion of the pad still works normally. It's just the left & right clicks under the touchpad that is disfunctional. I don't know if that's easy to fix.
