Memory

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

You can increase your computer memory by installing memory modules on the system board. See "Specifications" on page 205 for information on the memory supported by your computer. Install only memory modules that are intended for your computer.

NOTE: Memory modules purchased from Dell are covered under your computer warranty.

Your computer has two user-accessible SODIMM sockets, one accessed from beneath the keyboard (DIMM A), and the other accessed from the bottom of the computer (DIMM B).

NOTICE: If your computer has only one memory module, install the memory module in the connector labeled “DIMMA.”

NOTICE: If you need to install memory modules in two connectors, install a memory module in the connector labeled “DIMMA” before you install a module in the connector labeled “DIMMB.”

Removing the DIMM A Memory Module

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).

The DIMM A memory module is located under the keyboard.

1Follow the procedures in "Before You Begin" on page 161.

2Remove the hinge cover (see "Hinge Cover" on page 168).

3Remove the keyboard (see "Keyboard" on page 169).

NOTE: It is not necessary to disconnect the keyboard cable from the memory module cover.

4Lift the memory module cover but do not remove it.

NOTICE: To prevent damage to the memory module connector, do not use tools to spread the memory-module securing clips.

5Use your fingertips to carefully spread apart the securing clips on each end of the memory module connector until the module pops up.
