Adding Memory
In the future you may want to install memory modules to expand the
functionality of your notebook. Expansion memory modules are available
as options. For memory upgrades, use only unbuffered PC100 (CL2)
SDRAM SO-DIMMs (gold lead contacts). Refer to the Specifications flyer
that came with your notebook for the amount of memory pre-installed.
