@joejames1994 , welcome to the forum.
I believe that it has two memory slots. Here is the Maintenance and Service Guide for the laptop. On Pages 34 and 35 is a list of compatible memory sizes and instructions on removing and replacing it. Read the information carefully. Note that it emphasizes to update the BIOS before upgrading the memory. Also, on Pages 41 and 42 is a list of compatible M,2 SSD's and instructions for removing and replacing them. You can buy other manufacturer's M.2 drives.
