[. . . ] 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 the 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 the 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. Upgrading Your VAIO Computer > Adding and Removing Memory n 70 N Use the special bag supplied with the memory module or wrap the module in aluminum foil to protect it from ESD. Introducing any liquids, foreign substances, or objects into the memory module slots or other internal components of your computer will result in damage to the computer and any repair costs will not be covered by the warranty. Do not place the memory module in a location subject to: Heat sources such as radiators or air ducts Direct sunlight Excessive dust Mechanical vibration or shock Strong magnets or speakers that are not magnetically shielded Ambient temperature of more than 95°F (35°C) or less than 41°F (5°C) High humidity Handle the memory module with care. To avoid injuries to your hands and fingers, do not touch the edges of the components and circuit boards inside your computer.
