Hi @sergiozilb25651
Here's the service manual for the laptop.
Go to p.27 to view the procedure to remove/replace the memory.
The specifications show that the laptop supports up to a maximum of 32GB of DDR4 2666MHz sodimm memory in 2 slots i.e. 2 x 16GB modules.
If you want to match the 16GB memory that is already installed (is it 1 x 16GB or 2 x 8GB?) so that they're identical e.g. latency, frequency etc, you would need to check what information is shown on the module itself.
If you have to replace both modules (if 2 x 8GB is installed currently) then ensure that you get a "matched pair" to avoid any operating problems
