Removing SDRAM SODIMMs

To remove 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.

Step 3 Release the plastic clips from the top SODIMM, which releases the SODIMM from its socket. (See Figure 10.)
