Adding Memory
In the future you may want to install memory modules to expand the
functionality of your computer. You can increase memory to 192 MB on
the PCG-Z505JE and the PCG-Z505JEK and you can increase memory to
256 MB on the PCG-Z505JS and PCG-Z505JSK. The PCG-Z505JE/
PCG-Z505JEK has 64 MB of memory and the PCG-Z505JS/PCG-Z505JSK
has 128 MB of memory. For memory upgrades, use only PC-100 SDRAM
SO-DIMM (gold lead contacts).
❑
The procedures described below assume familiarity with the general
terminology associated with personal computers and with the safety
practices and regulatory compliance required for using and
modifying electronic equipment.
❑
Disconnect the system from its power source and from any
telecommunications links, networks, or modems before you open the
system or follow any of the procedures described below. Failure to do
so may result in personal injury or equipment damage.
❑
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.
