Step 4 When both ends of the SODIMM are released from the socket, grasp the ends of the SODIMM with your thumb and forefinger and pull it completely out of the socket. Place it in an antistatic bag to protect it from ESD damage.

Step 5 If necessary, repeat Step 3 and Step 4 to remove the bottom SODIMM.

Step 6 Proceed to the “Installing SDRAM DIMMs” section on page 15.

Installing SDRAM SODIMMs

To install SDRAM SODIMMs, follow these steps:

Step 1 Attach an ESD-preventive wrist strap and ensure that it makes good contact with your skin. Connect the equipment end of the wrist strap to the metal back plate of the chassis, avoiding contact with the connectors.

Step 2 On the mainboard, locate the SDRAM SODIMM socket. (See Figure 9.)

Caution Handle the SODIMM by the edges only; do not touch the memory modules, pins, or traces (metal fingers along the connector edge). Handle carefully. SODIMMs are ESD-sensitive components and can be damaged by mishandling.
