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.
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.
