Before you upgrade your computer
Observe proper safety precautions when you modify your computer. See Upgrading the computer system.
Caution:
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.
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.
