you may install an additional memory upgrade module.
The memory upgrade must be a dual-in-line (DIMM)
SDRAM module.

fully pry the screw covers out of the screw holes just
above both ends of your keyboard and remove the
two screws located within the screw holes.

horizontal. Carefully work the panel surrounding
the status indicator panel loose and set it aside.
4. Lift the edge of the keyboard that is closest to the
display panel upward, approximately one-quarter of
an inch, and then pull it away from you. Do not pull
too far, as it is still connected to your notebook.

memory upgrade module compartment.
