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.
Your computer has two user-accessible SODIMM sockets, one accessed from beneath the keyboard (DIMM A), and the other accessed from the bottom of the
computer (DIMM B).
To add or replace a memory module in the DIMM A connector:
1. Follow the procedures in "Before You Begin."
2. Remove the keyboard.
NOTICE: If you remove your original memory modules from the computer during a memory upgrade, keep them separate from any new modules that
you may have, even if you purchased the new modules from Dell. If possible, do not pair an original memory module with a new memory module.
Otherwise, your computer may not function at optimal performance.
