Nothing wrong with laptops, well, apart from the fact that your upgrade path is very limited. The problem you have is laptops are not as generic as PCs and not many people will have come across your model.
Last one I had there was a flap underneath to gain access to the memory.
It is often easier (and cheaper) to buy a newer one than try to source memory (some of it is specific to your model) for a very low gain in performance.
I am guessing that it is quite old.
