  • Btec National Diploma Level 3*IT Systems Troubleshooting and RepairHardware & Software Tools and Techniques

    Btec National Diploma Level 3

  • Btec National Diploma Level 3*Aims Discuss the types of hardware and software tools

    Look into what is the purpose of a multi-meter and a loop-back plug

    Discuss the terms BIOS, CMOS and POST

    Look at diagnostic software

  • Btec National Diploma Level 3*Hardware tools and techniquesA technicians toolkit should consist of conventional tools such as:

    Screwdrivers and other basic tools Bootable disk Diagnostic hardware Manufacturers specifications of hardware

    Btec National Diploma Level 3

  • Btec National Diploma Level 3*Hardware tools and techniquesElectrical faultsThese faults could lie within a

    PSU - power supply unitHardware componentCablingConnectors

    Btec National Diploma Level 3

  • Btec National Diploma Level 3*Hardware tools and techniquesWhat device can be used?

    Btec National Diploma Level 3

  • Btec National Diploma Level 3*Multi-meterA multi-meter can be a hand-held device useful for basic fault finding and field service work or a bench instrument which can measure to a very high degree of accuracy.

    They can be used to troubleshoot electrical problems in a wide array of industrial and household devices such as batteries, motor controls, appliances, power supplies, and wiring systems.

  • Btec National Diploma Level 3*Hardware tools and techniquesMonitoring devicesPinging

    This is a test that can be performed by a technician to ensure something is there and responding.

    Example will be given by your tutor.

  • Btec National Diploma Level 3*Hardware tools and techniquesSuitable Tools

    ESD wrist strap

    This is a strap that is connected to the computers chassis.

    It is used to channel any static electricity away from the technician and to the ground.

  • Btec National Diploma Level 3*Software tools and techniquesMonitoring and error loggingMonitoring the computer can make sense of why the performance of the computer has decreased in someway.

    Audit trailRecord details about each event that has occurred

    Event viewerAllows you to predict and identify sources of system problems by recording events in three logs based on type of event: security, system and applicationOthers include: Dr Watson and WinVNC
