Wtf Lab 2.3.4: Computer Disassembly

In this lab you will disassemble a computer using safe lab procedures and the proper tools. Use extreme care and follow all safety procedures. Familiarize yourself with the tools you will be using in this lab.

Note: If you cannot locate or remove the correct component, ask your instructor for help.

Instructor note: It is necessary to complete this lab only if your lab computers are completely set up already. The goal of this lab is to have the components separated and ready to assemble for Chapter 3, and for the students to demonstrate proper tool use. The students can also apply proper tool use in the Chapter 3 labs, where they will assemble a computer.

This lab does not include removing the motherboard, CPU, and cooling device from the computer because of the replacement cost of these items. If possible, allow students to remove these components from broken computers that are kept in the classroom for part identification and demonstration.

The following are the recommended tools for this lab:

■ Safety glasses or goggles

■ Antistatic wrist strap

■ Antistatic mat

■ Flat-head screwdrivers

■ Phillips-head screwdrivers

■ Torx screwdrivers

■ Part retriever (or tweezers or needle-nose pliers)

■ Thermal compound

■ Electronics cleaning solution

■ Can of compressed air

■ Parts organizer

■ Computer with hard drive installed

■ Plastic tub for storing computer parts

■ Antistatic bags for electronic parts

Step 1

Turn off and disconnect the power to your computer.

Step 2

Locate all the screws that secure the side panels to the back of the computer. Use the proper size and type of screwdriver to remove the side panel screws. Do not remove the screws that secure the power supply to the case. Put all these screws in one place, such as a cup or a compartment in a parts organizer. Label the cup or compartment with a piece of masking tape on which you have written "side panel screws." Remove the side panels from the case.

What type of screwdriver did you use to remove the screws?

A Phillips screwdriver or a hex driver are the most commonly used screwdrivers to remove case panels. Answers may vary.

How many screws secured the case cover to the chassis?

Answers may vary. Normally, there are two screws for each panel on a mid-tower case, but there can be anywhere from one to six screws for the case.

Step 3

Put on an antistatic wrist strap. One end of the conductor should be connected to the wrist strap. Clip the other end of the conductor to an unpainted metal part of the case.

If you have an antistatic mat, place it on the work surface and put the computer case on top of it. Ground the antistatic mat to an unpainted metal part of the case.
