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-Z505JE and the PCG-Z505JEK and you can increase memory to 
256 MB on the PCG-Z505JS and PCG-Z505JSK. The PCG-Z505JE/
PCG-Z505JEK has 64 MB of memory and the PCG-Z505JS/PCG-Z505JSK 
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.
!
Make sure you observe the proper safety precautions when you install a memory 
module 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.
