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 slots, DIMM A and DIMM B. DIMM A is located on top of the computer under the keyboard, and DIMM B is located on the bottom
of the computer under the memory module cover. DIMM A holds the basic memory module as configured from the factory. If you did not order additional
memory, DIMM B is empty. Generally, if you add memory, you use DIMM B. If you are upgrading memory, you may need to install memory in DIMM A and DIMM
B, depending on the extent of the upgrade.
