Upgrading Baseboard Components

Use the information in this chapter to upgrade or replace components on the system
baseboard (processor board). For information on tools needed, see Chapter 1. For a list of
safety related information see "Safety: Before You Remove the Access Cover" on page 1.
For a complete list of warnings and cautions regarding internal power, ESD, and proper
system cooling, be sure to read "Warnings and Cautions" in Chapter 1.
Caution: Installing or removing jumpers: A jumper is a small, plastic-encased
conductor that slips over two jumper pins. Newer jumpers have a small tab on top that
you can grip with your fingertips or with a pair of fine, needle-nosed pliers. If your
jumpers do not have such a tab, take care when using needle-nosed pliers to remove or
install a jumper; grip the narrow sides of the jumper with the pliers, never the wide sides.
Gripping the wide sides can damage the contacts inside the jumper, causing intermittent
problems with the function controlled by that jumper. Take care to gently grip, but not
squeeze, with the pliers or other tool you use to remove a jumper; you might bend or
break the stake pins on the board.

Baseboard

Use the information in the following sections to remove or install the baseboard.

Removing the Baseboard

Caution: The baseboard can be extremely sensitive to ESD and always requires careful
handling. After removing it from the system, place it component-side UP on a
nonconductive, static-free surface to prevent shorting out the battery leads. If you place
the board on a conductive surface, the battery leads may short out. This will result in a
loss of CMOS data and will drain the battery. Do not slide the baseboard over any
surface.
