add-in cards, and other components. If an ESD station is not
available, wear a wrist strap attached to a metal part of the
computer. Place cards on a conductive foam pad or inside the
conductive wrapper they came in; do not place the cards on top of
the wrapper.

Read the following items before attempting to upgrade or service the computer:
•
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.
•
Set up an equipment log to record the system model and serial numbers, all
installed options, and other information about the system. If you need this
information, it will be easier to consult the log than to open up and examine
the system.
•
HP recommends that you use an antistatic wrist strap and a conductive foam
pad when working on the system.
•
Disconnect the system from any telecommunications links, networks, or
modems, and then disconnect the system power source before performing
any of the procedures described in this guide. Failure to do so before you
open the system or do any procedures can result in personal injury or
equipment damage.
NOTE:
Disconnect the modem/telephone cable before disconnecting the power
cord from the PC.
To gain access to the inside of the computer, remove the side panel.
WARNING: Before installing and connecting your system to the
electrical power system, please read the safety information in the
Warranty & Support Guide.
