This computer comes with 1GB of DDR2 memory, but you can upgrade to 2GB and do it yourself by using this guide. The RAM is easy to access, but can be a little tricky to remove from its compartment so make sure you have the right tools.
Start with the bottom of the laptop facing up.
Locate the panel covering the RAM compartment.
Unscrew the two 5mm Phillips #0 screws.
Lift up the panel by the end with the screws and set it aside.
Rotate the device about 180 degrees to the left so you can access the RAM compartment more easily.
Using 2 prying tools, push the 2 buttons on the sides of one RAM module simultaneously – This will release the module, it will pop up and then you can pull it out.
Repeat the previous step for the second RAM module, which is located just underneath the first RAM module.
