Adding Memory
In the future you may want to install memory modules to expand the 
functionality of your computer. Your system comes with 64 MB of installed 
memory (64 MB x 1). By inserting optional memory modules in your 
computer's expansion slot, you can increase the memory up to 256 MB (128 
MB x 2). 64 MB and 128 MB expansion memory modules are available as 
optional memory modules. For memory upgrades, use only PC-100 SDRAM 
SO-DIMM (gold lead contacts). Sony computer supplies, accessories, and 
peripherals can be purchased from your Sony-authorized dealer or by 
contacting Sony at http://www.sony.com/accessories.
 
 
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 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 
The size of your memory may differ if you purchased a specially configured system.
Make sure you observe the proper safety precautions when you install memory 
modules in your computer. See the bulleted list below. Be careful when adding 
memory. Mistakes when installing or removing a memory module may cause a 
malfunction.
