    Introduction

    MI Introduction (LSI Quadrant I):

    Understanding how a PC is assembled and disassembled is a key component in the training for a computer technician. Knowledge of how the computer parts fit will help the technician solve repair and upgrade problems.

    IDE storage devices, such as the hard drive and CD-ROM drive, are the most common type of storage devices installed in todays PC. How can the computer technician ensure the cabling for these devices is properly oriented? Make sure that the colored stripe [usually red, sometimes blue] is oriented on the number 1 pin of the IDE port [both on the motherboard and the drive]. On the drives IDE port, the number one pin is usually closest to the power connector.

    Outline

    MI Outline (LSI Quadrant II): Instructor Notes:

    I. Introduce students to the computer assembly process to include A. Computer chassis (case) B. Power supply C. Motherboard configuration D. Configuration of connectors E. CPU interfaces F. RAM installation G. Hard drives and/or CD-ROMs installation H. Floppy drives connection I. First boot after assembly

    II. Safety guidelines

    A. Make sure workspace is clean and properly lit.

    B. Make sure the PC is turned off. C. Verify that the PC has been unplugged

    from the power source. D. Put on antistatic wrist strap. E. Create a backup of the PC configuration

    (most PCs will restore and reboot themselves).

    III. Steps in opening a CPU

    A. Note the type of PC being worked on (manufacturer, model, hard drive capacity/space, external location of hard drive).

    B. Remove the power cord from the monitor, then unplug, unscrew the monitor cable from the back of the PC, and set the

    monitor aside. C. Locate the screws on the back side of the

    case. D. Remove the screws and place them in a

    tube container for safe keeping. E. Carefully remove the case, watching out for

    internal wires and cables. IV. Internal PC components

    A. Near the front of the case one or more of the following:

    1. Shelf bracket 2. Floppy drive 3. Hard drive 4. Zip drive 5. CD-R 6. DVD/CD-R 7. DVD/CD-RW

    B. Directly below or to the right of the shelf bracket

    1. Motherboard a. CPU (Athlon or Pentium chip) b. Memory Modules (SIMM, DIMMS,

    or RIMM chips) c. Buses (small wires that allow

    information to flow through the PC) d. Transistors e. Resistors

    C. Attached to the motherboard 1. Expansion cards

    a. Internet (via modem or Ethernet) b. Enhanced graphics cards (AGP 4

    or 5) c. PCTV card (allows images to be

    projected to a TV in some PCs) d. USB ports e. FireWire ports f. Audio ports g. Parallel ports h. Serial ports i. Keyboard port j. Mouse port

    D. Toward the back of the case 1. Power supply

    V. Diagramming internal PC components

    A. Symbols B. Cables/connections C. Plug locations/configurations/types D. DIP switch locations/status E. Motherboard: memory sockets, switches,

    power supply connection F. Labels G. Legend H. Scale

    VI. Steps in disassembling a PC

    A. Note and record each part, drive, cable, and connection.

    B. Avoid forcing the removal of parts (if they dont come out easily; STOP and assess why).

    C. Remove the drives with their connecting cables (makes the job easier by allowing more room for work).

    D. Place the removed parts in a separate space on the work area.

    E. Remove the expansion cards, noting the bays in which they were originally located.

    F. DO NOT TOUCH the pin connectors on the cards with your bare hands.

    G. Unplug and carefully remove the power supply from the machine. EXTRA CARE should be taken with the power supply as it still has a power charge in it.

    H. Gently remove the CPU from the Motherboard by unlocking the ZIF or LIZ (Zero Insertion Force) socket. If the CPU is in a push-in socket, then use the CPU removal tool that comes in the kit. Note the position prior to removal to prevent damage when reassembling.

    I. Carefully remove the Motherboard if needed. Check to see if this is necessary (ask your instructor if you are in doubt).

    J. Evaluate the removed components as needed, and note all information for future reference.

    VII. Reassembling a PC

    A. If all parts are found to be in good condition, the student can begin reassembling the PC using the diagram created during disassembly.

    VIII. Steps in closing a PC

    A. Replace the case, watching out for int
