Installing Memory
The amount of preinstalled memory can vary, depending on the system configuration purchased. Your computer may ship
with all available memory slots filled. For memory replacement or upgrades, use the correct memory module for your
computer's configuration.See the specifications sheet for your computer on the Sony Online Support Web site at
http://www.sony.com/pcsupport , for details about the amount of memory installed in your computer.
Before upgrading your computer
Disconnect the computer from its power source and from telecommunications links, networks, or modems, before you open
the unit or follow any procedures described in this section.
Failure to disconnect your computer from its power source may result in personal injury or equipment
damage. Always turn the power off before you open the system or connect your computer to peripheral equipment.
Otherwise, damage may occur to the integrated circuits in your computer.
Electrostatic discharge (ESD) can damage disk drives, add-on cards, and other components. Follow the procedures
described here 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 (for example, cellophane wrappers). Ground yourself by
maintaining continuous contact with an unpainted metal portion of the chassis while performing the procedure.
Your computer may not be equipped with all of the hardware features mentioned in this section. The interior hardware
configuration of your system may vary from the illustrations, depending on the computer purchased.
