Precautions and procedures
The procedures described below 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.
Sony recommends that memory upgrades be performed by an authorized Sony Service Center. To find
the nearest center or agent, go to: http://www.sony.com/pcsupport .
When installing a memory module in your computer, make sure you read the proper safety precautions below.
Mistakes that occur when installing or removing a memory module may cause a malfunction.

Disconnect the computer from its power source and from any telecommunications links, networks, or modems before
you install or remove a memory module. Failure to do so may result in personal injury or equipment damage.

Electrostatic discharge (ESD) can damage disk drives and other components. Perform the procedures described
below 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 install the module. The package protects the
module from ESD.

Use the special protective package to store a memory module and prevent ESD, or wrap the memory module in
aluminum foil.
