Instructions

  1. 1

    Close your laptop and invert the unit so that the bottom is visible. Place the computer on a flat, sturdy surface.

  3. 3

    Slide the battery lock to an unlock position. Remove the battery pack by sliding the battery away from the computer.

    If a memory module is installed in the slot, remove it by pressing outward on the latches located on either side of the module. Simultaneously slide the module out of the memory slot.

    Insert the upgrade SO-DIMM into the memory slot at a 20-degree angle. Pivot the SO-DIMM downward. The module will snap into place.
