Chapter 3: Replacing Pre-Installed
Components
3.1 Introduction
This chapter explains how to replace pre installed compo-
nents including the motherboard, LED control board, HDD,
and CD-ROM drive.
Take note of the precautions in this section when installing
your system.
3.1.1 Work Area
Make sure you have a stable, clean working environment.
Dust and dirt can get into components and cause malfunc-
tions. Use containers to keep small components separated.
Putting all small components in separate containers keeps
them from becoming lost. Adequate lighting and proper tools
can prevent you from accidentally damaging the internal
components.
3.1.2 Tools
The procedures that follow require only a few tools, including
the following:
•
A cross head (Phillips) screwdriver
•
A grounding strap or an anti-static pad
Most of the electrical and mechanical connections can be dis-
connected using your fingers. It is recommended that you do
not use needle-nosed pliers to remove connectors as these
can damage the soft metal or plastic parts of the connectors.
