Adding and replacing system board components
To work with the hardware components on the system
board, you must first unplug the system and remove the
system unit cover.
To access the section of the system board that you need
to work with, you might need to remove adapter cards
and drives. If you have a minitower system, you might
also need to remove the riser card. With the system
board exposed, you can work with the processor, cache
and system memory modules, and the system battery.
Once you have completed your hardware changes and
put the cover back on your system unit, you might need
to enter the Setup Utility. For information about whether
this is a step you need to take, see ”Updating the Setup
Utility” on page 72.
The system boards for the desktop and minitower
systems are identical. The following sections contain
instructions for working with the hardware components
on your system board:
If you have a desktop system and you have
not removed the cover from your system
unit, see ”Opening a desktop system unit”
on page 58.
If you have a minitower system and you
have not removed the cover from your
system unit, see ”Opening a minitower
system unit” on page 59.
