Adding Memory
In the future you may want to install memory modules to expand the
functionality of your computer. You can increase memory to 256 MB by
installing an optional memory module.
❑ 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.
