NOTICE: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface (such as a connector on the back of the computer).

NOTICE: If there is a memory module in DIMM 2, remove it prior to removing the memory module from DIMM 1. Failure to do so could result in damage to both memory modules

Turn the computer over and loosen the three captive screws and the M2.5 x 5-mm screw. Remove the module cover.

Remove the module from the connector.
