You can increase your computer memory by installing memory modules on the system board. See the "Specifications" section in your User's Guide for

information on the memory supported by your computer. Install only memory modules that are intended for your 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.
