Depending on the model you purchased, either 128 MB of memory is
preinstalled in one of the two available memory module bays (128 MB x 1), or
256 MB of memory is preinstalled utilizing both memory module bays
(128 MB x 2). You can replace both memory modules with optional 256 MB
memory modules to increase memory up to 512 MB. For memory upgrades, use

Precautions and Procedures
❑
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.
❑
Use the special bag for preventing ESD or use aluminum foil when you store
the memory module.
Make sure you observe the proper safety precautions when you install
memory modules in your notebook. See the bulleted list below. Be careful
when adding memory. Mistakes when installing or removing a memory
module may cause a malfunction.
