Before purchasing any M.2 SSD I strongly suggest go to Lenovo Comunity Forum, Register there and Create a Thread about the same - Which M.2 SSD will compatiable with your model number (Make sure the model number, not the Serial Number because there Triliions of varient produced for all over the world) - This is seems ridiculas but I'm victim of the same about M.2 SSD comaptiablity issue, but thanks to Amazon Refund policy I got my money back....So always buy from Amazon IN.
Also Download Hardware Maintance Manual in the PDF form to familier with your machine - It is on the upper right side of the driver download page / support page.
Also in the support page there are the Spare Part Listing - In that section you can dig and land into M.2 Comaptiability section, If you able to decode model number of the M.2 SSD then you can buy with Eyes Closed. In my case there are Samsung and WD models listed as compatible but I can't decode that and get relevent product page at Amazon IN.
Lastly My E14 is AMD machine, But your one is Intel - You may not even face this issue at all.......All Hail To Intel.
