20A7 (and 20A8) Machine-Type belongs X1C Generation 2.
There are no X1C Gen4 machine, "only" Gen3 (MT 20BS, 20BT)

Specification of platform is on the page below:
http://psref.lenovo.com/Product/158?MT=20A7

Detailed specification of your model will appear on the site above a bit later. Or download the following file and have a look at your model:
http://www.lenovo.com/psref/pdf/ThinkPad.pdf

Information about parts factory installed in your laptop is here (type in laptop s/n):
http://support.lenovo.com/us/en/ibasepartslookup

Remove s/n from your post above for your privacy.
