It depends on the processor installed

@mario_soza2001 

You got really good information from @Prométhée  -- but you need to pay close attention to where he said " non-customer-accessible/upgradable memory module slots slots" -- as that means there is no access panel to open to change the memory sticks.  So, if you try that on your own, you risk damaging it and that will void the warranty.

My suggestion is to leave it alone!

It's pretty vicious @WAWood 
non-customer-accessible / upgradable
This implies that it is not possible for the user but for a professional yes ...
This is indicated for many models, because you have to dismantle almost everything ...
But many users do it themselves, to avoid a certain cost.
Of course, if you do not have the tools, which you do not know how to do, it is better to avoid!
Here there are just pictures, if you want to give it a try, think about looking for videos, there are quite a few on practically all models!
Otherwise, go to an IT professional
