Adding and Replacing Parts 149
You can increase your computer memory by installing memory modules on the
system board. See "Specifications" on page 181 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.
