To install the memory, follow these steps:

  1. Turn off the system; then disconnect the ac adapter and all cables from the system.
  2. Close the system display, and turn it over.
  3. Remove the battery.
  4. Loosen the screw on the memory slot cover; then remove the cover.

    Remove the memory cover.

    If the SO-DIMM is already in the memory slot, remove it to make room for the new one by pressing out on the latches on both edges of the socket at the same time. Be sure to save it for future use.

    Release the latches
  5. Find the notch on the side of the SO-DIMM.
    Note: To avoid damaging the SO-DIMM, do not touch its contact edge.
  6. With the notched end of the SO-DIMM toward the right side of the socket, insert the SO-DIMM into the socket at an angle of about 20 degrees (1); then press it firmly (2).

    Insert the memory
  7. Pivot the SO-DIMM downward until it snaps into place.
  8. Make sure that the card is firmly fixed in the slot and does not move easily.
  9. Replace the memory slot cover by aligning the back side of the cover first and then tightening the screw.
    Note: When you have added or upgraded a memory card, do not use your system until you have closed the cover. Never use the system with the cover open.
  10. Put the battery back in place, turn the system over again, and reconnect the cables.
