Replacing or installing DIMMs
IMPORTANT: You must unplug 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
briey touching a grounded metal
object. For more information, refer to Electrostatic discharge on page 33.
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 (Preparing for disassembly on page 8).
2. Remove the access panel (Removing and replacing the access panel on page 18).
3. To remove a DIMM, press outward on one latch on either side of the DIMM (1), and then pull the DIMM
out of the socket (2).
