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-Z505LE and the PCG-Z505LEK and you can increase memory to 256 MB
on the PCG-Z505LS and PCG-Z505LSK. The PCG-Z505LE/PCG-Z505LEK
has 64 MB of memory and the PCG-Z505LS/PCG-Z505LSK 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.
Sony recommends memory upgrades be performed by an authorized Sony Service
Center or Sony authorized agent. To find the nearest center or agent, see
