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. Personal
injury or equipment damage may result from failure to take these precautions.
❑ Disconnect the system from its power source and from any
telecommunications links, networks, or modems before you open the
system.
❑ 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 bag for preventing ESD or use aluminum foil when you store
the memory module.
Sony recommends memory upgrades be performed by an authorized Sony
Service Center. To find the nearest center or agent, see

Observe the proper safety precautions when installing memory modules in
your notebook. See the bulleted list below. Use care when adding memory.
Mistakes when installing or removing a memory module may cause a
