Already it has 8 GB DDR4-2133 SDRAM (2 x 4 GB), you can put two 8gb modules of exact same configuration, speed, voltage as given in the manual (PC4, 17000, 2133-MHz)� and each other in the two slots. Since it is not customer accessible or upgradable, please get help from certified HP technicians to do the upgrade. Else if something breaks in the process it'll void the warranty.

Or

Your laptop came with Windows 10 64 bit.
Get at least 256 GB capacity SSD for using recovery media to successfully factory reset OS. You can do a clean install of Windows 10 also after replacement, by using UEFI bootable installation media created via windows media creation tool.
