Lenovo Thinkpad Yoga 370 - WWAN or Non-WWAN



How can I find if my model type of Lenovo ThinkPad Yoga 370 type 20JJ-S4W61C is WWAN or not?


WWAN model: 8GB 2133MHz DDR4 soldered to systemboard

Non-WWAN model: 16GB max / 2133MHz DDR4, one DDR4 SO-DIMM socket


I dont see it in Lenovo Vantage utility and even can't searched it google/duckduckgo.


And of course, how can I identify it without opening a laptop chassis physically.


thank you

Hi DominikK! 


Welcome to the community forums. 


We can't find the exact MTM(20JJ-S4W61C) of the laptop when we search it online or on our tools.


The best way to get the exact information about WWAN is by looking up the part on our parts lookup page:


Just enter the serial number and check if there is WWAN adapter. It should the WWAN adapter if available.


I hope that helps.
