Follow the steps below to install extra memory.
 

1. Turn off the machine's power switch.
2. Disconnect the interface cables from the machine, and then unplug the power cord from the AC power outlet (electrical socket).
   Always unplug the power cord from the AC power (electrical socket) outlet before installing or removing the SO-DIMM.
3. Remove the plastic (1) and then the metal (2) SO-DIMM covers.
   
   
    
4. Unpack the SO-DIMM and hold it by its edges.
   To prevent damage to the machine from static electricity, DO NOT touch the memory chips or the board's surface.
5. Hold the SO-DIMM by the edges and align the notches in the SO-DIMM with the protrusions in the slot. Insert the SO-DIMM diagonally (1), then tilt it toward the interface board until it locks into place (2).
   
   
    
6. Put the metal (2) and then the plastic (1) SO-DIMM covers back on.
