Week 4: Performing Computer Hardware Services
Objective: After the completion of the chapter, students will be able to:
 Disassemble a computer system
 Document specifications and information on hardware
 Assemble a computer system
 Install Input / Output devices

I. Disassembling a Computer
You might be wondering why the lesson starts with disassembly and not assembly
itself? Simply because we want to learn how to disassemble a computer so we can assemble
it again from how we took out the parts.
It is because in the industry, you will be performing disassemble especially in servicing,
compared to building a new computer and repairing and maintaining the computers in the
workplace. You have to be familiar especially first in the system unit.

Preparing for Disassembly
Before going into the disassembly proper, you have to prepare all the materials that
you will need.
Make sure to:
 The system unit you will disassemble is UNPLUGGED!
 Wear your antistatic wrist strap.
 Lay out the antistatic mat.
 The table is large and long enough.
