Memory
You can increase your computer memory by installing memory modules on the system board. See
"Specifications" on page 123 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

NOTICE: To avoid damaging the system board, you must remove the main battery before you begin working inside
the 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.
