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 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.
1 Follow the procedures in "Before You Begin" on page 141.
2 Remove the hinge cover (see "Hinge Cover" on page 147).
