Upgrading and Maintaining
Your Sony PC
In the future you may want to install additional boards to expand the
functionality of your PC. This section describes how to open your PC and
insert add-in boards, add memory, and replace the cover. This section
also explains how to change the lithium battery. For more information on
upgrading your Sony PC, see the online System Reference Manual.
The procedures in this section assume that you are familiar with the
general terminology associated with personal computers and with the
safety pract^es and regulatory compliance required for using and
modifying electronic equipment. Read "Notes on Use" on page 109
before upgrading your Sony PC.
Caution
Always switch the power off before you open the system or connect your PC to
peripheral equipment; otherwise, damage may occur to the integrated circuits in
your PC.
Electrostatic discharge (ESD) can damage disk drives, add-in cards, and other
components. Do the procedures described here 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 continuous contact with an unpainted metal portion of the
chassis while performing the procedure.
