To remove the memory module, flip the laptop over and remove the 6 screws from the base cover. Find and loosen the two screws at the back of the cover and gently pry the cover away from the hinges. Lift the base cover, identify and unlatch the memory module. Grasp the edges and remove the module from the system.
To reinstall the memory module, realign the notch with the tab and place the module back in its correct spot. Secure the base cover with the screws.
