Removal and Replacement Procedures - Convertible Minitower (CMT) Chassis

6.9 Memory

CAUTION: The memory module sockets have gold metal contacts. When upgrading the memory, it is

important to use memory modules with gold metal contacts to prevent corrosion and/or oxidation

resulting from having incompatible metals in contact with each other.

CAUTION: Static electricity can damage the electronic components of the computer or optional cards.

Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching

a grounded metal object. Refer to Section 5.2, “Electrostatic Discharge Information” for more information.

CAUTION: When handling a memory module, be careful not to touch any of the contacts. Doing so

may damage the module.

1. Prepare the computer for disassembly (Section 6.1).

2. Remove the computer access panel (Section 6.5).

WARNING: To reduce risk of personal injury from hot surfaces, allow the internal system components to

cool before touching.

3. Open both latches of the memory module socket 1, and insert the memory module into the

socket 2. Refer to Appendix F, “Memory” for the correct sequence for installing memory

modules to get optimal performance.

✎

A memory module can be installed in only one way. Match the notch on the module with the tab

on the memory socket.

4. Push the module down into the socket, ensuring that the module is fully inserted and

properly seated. Make sure the latches are in the closed position (3).

5. Repeat steps 3 and 4 for any additional modules that you want to install.
