There may be another 2 Gb stick elsewhere.  Memory doesn't have to be in the same place in laptops.  Some come with default memory in one hard to access location and have another slot in an easy to access slot elsewhere.  I struck an HP or Compaq (can't remember which one like that) that had memory under keyboard and another slot for memory at the back.

And which laptop is this, so we can look at the manual for it?

probably you have two 2GB RAM modules inside your laptop - so it is 4 GB together

It also might be a built in memory (2Gb) which is not removable.

Clearly your laptop has a pair of 2GB modules, as noted above.

The real question is whether the 2nd module is soldered to the motherboard, or is in another slot located somewhere else (often under the keyboard.   That will determine whether it can also be replaced.

As noted above, post the model # of the laptop, and we can look up the specifications for you.    As long as it can support modules > 2GB, you can at least upgrade the easily removable module.    If the other module is also removable, you can upgrade even more.

By the way, confirm that you're running a 64-bit OS (Right-click on Computer, select Properties, and it will show you).    If not, 4GB is all you can use anyway.

He already mentioned that he has 64bit so he's good.
