It provides detailed graphics showing the proper installation procedure for each component of the computer. Where appropriate, this chapter explains other methods of component installation. Hands-on labs allow the student to assemble a computer with an emphasis on safe practices.  This chapter is important because it gives students the opportunity to learn about all of the components of a desktop computer and has them assemble one in a lab. The chapters and labs that follow Chapter 3 build on this basic knowledge of the computer. For those students who do not have access to a physical desktop computer in the lab, Chapter 3 also provides a Virtual Desktop. The Virtual Desktop labs demonstrate desktop assembly through animation and student interaction.

Presentation_ID 7 © 2008 Cisco Systems, Inc. All rights reserved.Cisco Confidential Chapter 3: Classroom Management  Disassemble the computer in a step by step process, keeping the students moving through the process together. For example, everyone takes the cover off after the instructor has explained the problems associated with the case. Then move on to the next part to be removed. Reassembly works best if you allow the students to work at their own pace.  If disassembling the computer in teams, rotate to the next team member every five minutes. The teacher might want to control the rotation to ensure hands-on time for each student.  Students that finish quickly should help others troubleshoot issues.  Do an Internet search on the keywords how to build a computer and find good and bad points to demonstrate in class.

Presentation_ID 8 © 2008 Cisco Systems, Inc. All rights reserved.Cisco Confidential Chapter 3: Teaching Analogies  Computer reassembly is like a jigsaw puzzle. All the pieces fit nicely together to make a nice picture when done properly. You cannot force a puzzle piece or a computer component into the wrong spot.

Presentation_ID 9 © 2008 Cisco Systems, Inc. All rights reserved.Cisco Confidential  Describe something you have disassembled and the reassembly did not go very well. Tell us what happened.  What do you do when you drop a screw?  What do you do if you have parts left over?  Why are BIOS beep codes and text messages important to a technician?  What is important about pin 1 on a cable or connector?  What happens when screws are too tight?  What kind of damage can ESD cause to computer components? Chapter 3: Suggested Class Discussions

Presentation_ID 10 © 2008 Cisco Systems, Inc. All rights reserved.Cisco Confidential  Allow students to troubleshoot their own computer reassembly problems. Put the student name(s) on computers that do not work and have them continue troubleshooting the computer problems during the next class period.  Stress cleanliness in the work area by putting away tools and straightening cables.  Keep broken equipment separated from components that work; have boxes for each category if possible.  If the class time is limited, integrate chapters 3 and 4. Students do preventive maintenance at the same time as disassembly/reassembly. Chapter 3: Best Practices
