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.
❑ 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.
Sony recommends that memory upgrades be performed by an authorized
Sony Service Center. To find the nearest center or agent, go to:
