I know it has two slots, but that's all I know.

The easiest way to check the number of slots and their availability, Is through Task Manager as per my Image below.

Spoiler:

I don't have the need, nor the expertise to upgrade the RAM myself though xD

If 16GB Is serving you well and you're not planning on Increasing your workload, then there's no point In upgrading.

In terms of Installing additional Ram, It's an extremely simple process that literally takes only a few minutes. With laptops, It's as simple as sliding It Into the slot and clipping It In.
