Lab 4.2 Computer Disassembly/Reassembly

Objective: To disassemble and reassemble a computer correctly

Parts: A computer to disassemble

A tool kit

An antistatic wrist strap (if possible)

Note: Observe proper ESD handling procedures when disassembling and reassembling a

computer.

Procedure: Complete the following procedure and answer the accompanying questions.

1. Gather the proper tools needed to disassemble the computer.

2. Clear as much workspace as possible around the computer.

3. Power on the computer.

Why is it important to power on the computer before you begin?

External Cables

4. Turn off the computer and all peripherals. Remove the power cable from the wall outlet

and then remove the power cord from the computer.

5. Note where the monitor cable plugs into the back of the computer. Disconnect the moni-

tor including the power cord and move it to a safe place. Take appropriate notes.

6. Remove all external cables from the back of the computer. Take notes on the location of

each cable. Move the peripheral devices to a safe place.

Did the mouse cable connect to a PS/2 or USB port?

Computer Case Removal

7. If possible, remove the computer case. This is usually the hardest step in disassembly if

the computer is one that has not been seen before. Diagram the screw locations. Keep the

cover screws separate from other screws. An egg carton or a container with small com-

partments makes an excellent screw holder. Label each compartment and reuse the con-

tainer. Otherwise, open the case as directed by the manufacturer.

Adapter Placement

8. Make notes or draw the placement of each adapter in the expansion slots.

9. On your notes, draw the internal cable connections before removing any adapters or

cables from the computer. Make notes regarding how and where the cable connects to the

adapter. Do not forget to include cables that connect to the motherboard or to the com-

puter case.

List some ways to determine the correct orientation for an adapter or cable.
