Memory

You can increase your computer memory by installing memory modules on the system board. See Specifications 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.

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

NOTICE: To prevent damage to the system board, remove the main battery before you service the computer.

The computer has two memory module connectors labeled "DIMM A" and "DIMM B." DIMM A is located on top of the system board (under the keyboard), and DIMM B is located on the bottom of the system board under the memory module cover. If only one memory module is installed, it must be installed in DIMM A, as configured from the factory. If you did not order additional memory, DIMM B is empty. Generally, if you add memory, you add by installing a memory module in DIMM B. If you are upgrading memory, you may need to remove and install memory modules in both DIMM A and DIMM B, depending on the extent of the upgrade.

To install a memory module in DIMM A:

1.Follow the procedures in Before You Begin.

2.Remove the hinge cover (see Hinge Cover).
