I have the same laptop.
What I didnt know that it is built it. meaning its soldered and cannot be removed.
Last friday I bought an 8gb ram for this because I thought it can be removed.
It turns out it cannot be removed. Now I am running a 12gb unmatched ram.
Which im not sure if unmatched is going to be a problem
So right now, it is impossible to get it to 16gb. You will have 20gb if you buy a new 16gb
