It was very trivial, and in the past I did had 4GB set. At some point I must have changed it (I don't recall doing it, but I did it anyway), and since I previously had it set to 4GB, I did not think of that. Then, probably, even if I saw it, I overlooked it, since I mistakenly thought that the 4GB setting was for 4GB or more. Once I set the switch to 4 GB all my RAM "returned" ;) Thank you for your reply.
