Hi,

When upgrading the RAM of your laptop you'll need to consider if it can really take up to 4GB and the frequency should be match with the old RAM that is inside it. But yes if your laptop can take up to 4GB that would be a good upgrade for your laptop. Can you please provide us more information about your laptop as well so we can give you more details about upgrading it. :)
