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 this section.

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 your computer. If a memory module is not detected by the computer

or the Windows operating system becomes unstable, contact your sales dealer or the manufacturer of your memory

module.

❑ Electrostatic discharge (ESD) can damage electronic components. Before touching a memory module, ensure the

following:

❑ The procedures described in this document assume user familiarity with the general terminology associated with

personal computers and with the safety practice and regulatory compliance requirements for using and modifying

electronic equipment.

❑ Turn off your computer and disconnect it from its power source (that is, AC adapter) and from any telecommunication

links, networks, or modems before you remove any cover or panel from the computer. Failure to do so may result in

personal injury or equipment damage.

❑ 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 before you are ready to change the module. The package protects the

module from ESD.
