Upgrading Your VAIO Computer > Adding and Removing Memory n 70 N Adding and Removing Memory If you want to expand the functionality of your computer, you can increase the amount of memory by installing optional memory modules. Before you upgrade your computer's memory, read the notes and procedures in the following pages. Notes on adding/removing memory modules Be careful when changing memory. Improper installation of memory modules may cause damage to your system. This damage may void your manufacturer's warranty. 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. Using your computer in low temperature conditions may produce a residual image on the LCD screen. When the computer returns to normal temperature, the screen returns to normal. A residual image may appear on the LCD screen if the same image is displayed for a long period of time. The residual image disappears after a while. You can use a screen saver to prevent residual images. The LCD screen becomes warm during operation. This is normal and does not indicate a malfunction. The LCD screen is manufactured using high-precision technology. You may, however, see tiny black points and/or bright points (red, blue, or green) that continuously appear on the LCD screen. This is a normal result of the manufacturing process and does not indicate a malfunction. Use a soft, dry cloth to wipe the surface of the LCD screen.
