Installing DIMMs

CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power to drain

before adding or removing memory modules. Regardless of the power-on state, voltage is always supplied to

the memory modules as long as the computer is plugged into an active AC outlet. Adding or removing

memory modules while voltage is present may cause irreparable damage to the memory modules or system

board.

The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is important

to use memory modules with gold-plated metal contacts to prevent corrosion and/or oxidation resulting

from having incompatible metals in contact with each other.

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.

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 (Preparation for disassembly on page 21)

2. Remove the access panel (

Access panel on page 22)

3. Open both latches of the memory module socket (1), and insert the memory module into the socket (2).

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

on the memory socket.

Populate the DIMM1 socket first.

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. Replace the computer access panel.

6. Reconnect the power cord and turn on the computer.

7. Lock any security devices that were disengaged when the access panel was removed.
