CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
CAUTION: 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.
NOTICE: If your computer has only one memory module, install the memory module in the connector labeled "DIMM A," which is underneath the keyboard.
NOTICE: If you remove your original memory modules from the computer during a memory upgrade, keep them separate from any new modules that you may have, even if you purchased the new modules from Dell. If possible, do not pair an original memory module with a new memory module. Otherwise, your computer may not function at optimal performance.
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: To prevent damage to the memory module connector, do not use tools to spread the memory-module securing clips.
If you are replacing a memory module, ground yourself and remove the existing module:
Use your fingertips to carefully spread apart the securing clips on each end of the memory module
connector until the module pops up.
Remove the module from the connector.

NOTICE: Insert memory modules at a 45-degree angle to avoid damaging the connector.
Ground yourself and install the new memory module:
Align the notch in the module edge connector with the tab in the connector slot.
Slide the module firmly into the slot at a 45-degree angle, and rotate the module down until it
clicks into place. If you do not feel the click, remove the module and reinstall it.
NOTE: If the memory module is not installed properly, the computer may not boot properly. No error message indicates this failure.
DIMM B
NOTICE: If you need to install memory modules in two connectors, install a memory module in the connector labeled "DIMM A" before you install a module in the connector labeled "DIMM B." Insert memory modules at a 45-degree angle to avoid damaging the connector.
Turn the computer over, loosen the captive screw in the memory module cover, and then remove the
cover.

NOTICE: If the cover is difficult to close, remove the module and reinstall it. Forcing the cover to close may damage your computer.
Insert the battery into the battery bay, or connect the AC adapter to your computer and an electrical
outlet.
Turn on the computer.
As the computer boots, it detects the additional memory and automatically updates the system configuration information.
To confirm the amount of memory installed in the computer:
In the Microsoft® Windows Vista operating system, click Start ® Help and Support® Computer Information.
In the Microsoft Windows® XP operating system, right-click the My Computericon on your desktop, click Properties, and then click General.
