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 193 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 153.
