Sony PCG-FX170 Manual

In the future you may want to install memory modules to expand the 
functionality of your computer. You can increase memory up to 512 MB 
(256 MB x 2), by installing optional memory modules. For selected models 128 
MB of memory is pre-installed (128 MB x 1); for other models, 64 MB of 
memory is pre-installed (64 MB x 1). You can add an expansion memory module 
(64 MB, 128 MB, or 256 MB) in the memory module bay. Expansion memory 
modules are available as options. For memory upgrades, use only PC100 (CL2) 
SDRAM SO-DIMM (gold lead contacts).

❑

The procedures described below assume you are familiar with the general 
terminology associated with personal computers and with common safety 
practices required for using and modifying electronic equipment.

❑

Disconnect your 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. Personal injury or 
equipment damage may result from failure to take these precautions.

❑

Electrostatic discharge (ESD) can damage memory modules 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.
