Adding Memory
In the future you may want to install memory modules to expand the
functionality of your notebook. Depending on the model you purchased, either
128 MB of memory is pre-installed in one of the two available memory module
bays (128 MB x 1), or 192 MB is pre-installed utilizing both memory module
bays (128 MB x 1, 64 MB x 1). You can increase memory up to 512 MB
(256 MB x 2), by installing optional memory modules (64 MB, 128 MB, or 256
MB) in the memory module bays. Expansion memory modules are available as
options. For memory upgrades, use only PC100 (CL2) SDRAM SO-DIMM (gold
lead contacts).
Before you start
❑
The procedures described below assume you are familiar with the general
terminology associated with personal notebooks 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.
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.
