Upgrading Your VAIO Computer
Adding and Removing Memory
If you want to expand the functionality of your computer, you can increase the memory by installing optional memory modules.
Before you upgrade your computer's memory, read the notes and procedures in the following pages. The number of available
slots depends on the configuration of your model.
Notes on adding/removing memory modules
❑ Be careful when changing memory. Improper installation of memory modules may cause damage to your system. This
damage may void your manufacturer's warranty.
❑ Only use memory modules that are compatible with the computer. If a memory module is not detected by the computer
or Windows becomes unstable, contact your sales dealer or the manufacturer of your memory module.
❑ Electrostatic discharge can damage electronic components. Before touching a memory module, ensure the following:
❑ The procedures described in this document assume familiarity with the general terminology associated with personal
computers and with the safety practices and regulatory compliance required for using and modifying electronic
equipment.
❑ Turn off the computer and disconnect the system from its power source (that is, battery or AC adapter) and from any
telecommunication links, networks, or modems before you open the computer. Failure to do so may result in personal
injury or equipment damage.
❑ Electrostatic Discharge (ESD) can damage memory modules and other components. Install the memory module only
at an ESD workstation. If such a station is not available, do not work in a carpeted area, and do not handle materials
that produce or hold static electricity (cellophane wrappers, for example). Ground yourself by maintaining contact with
an unpainted metal portion of the chassis while performing the procedure.
❑ Do not open the memory module package until you are ready to change the module. The package protects the module
from ESD.
