Opening and Closing the PC
Preparing the PC
Before you upgrade any component in your PC, you
need to prepare the PC so that you can safely handle
it and the components.
Read the following items before attempting to upgrade
or service the PC:
• These procedures 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.
• Write down and save the system model and
serial numbers, all installed options, and other
information about the system. It’s easier to consult
this information than to open up and examine
the PC.
• It is recommended that you use an antistatic wrist
strap and a conductive foam pad when working on
the system.
ARNING: Always disconnect the modem
cord from the telephone system, and then
disconnect the PC from the power source
before removing the front and side panels
of the PC. Failure to do so before you
open the PC or do any procedures can
result in personal injury or equipment
damage.
