When you turn your laptop over, I believe the RAM area is under the door right next to the battery. You hard drive is at the bottom left and your wireless card is at the bottom center. Pretty much all you do is unscrew that door and slide the module into an empty socket. Look at how the other module is inserted and try your best to match it. You'll probly have to insert it at a slight up angle and push it down gently to secure it.
