You will be able to unscrew the back of you laptop, and see the current Memory Chips in there, remove them and replace them with the new memory sticks.
This isn't your exact laptop model, but the procedure will be the exact same. The chips will just be in a slightly different location. You may have to unscrew a different looking compartment on the back. http://www.youtube.com/watch?v=sTm4AhdrCCE
