Chapter 9. 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. Before removing the cover or working
with internal components, review “Safety information” on page xiii. If you have not
removed the cover from your system unit, see “Opening the system unit” on
page 7-5.
To access the section of the system board that you need to work with, you may have
to remove adapter cards and drives. With the system board exposed, you can work
with the connectors, 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 BIOS Configuration/Setup Utility to update
the settings. The system board varies with the machine type. Please comprehend
the machine type before you want to identify the parts and connector of the system
board.
