  Removing a Memory Module

  Replacing a Memory Module

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).

You can increase your computer memory by installing memory modules on the system board. See "Specifications" in your Owner's Manual for information on the memory supported by your computer. Install only memory modules that are intended for your computer.

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."

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