Btec National Diploma Level 3 1
IT Systems Troubleshooting and Repair
Hardware & Software Tools and Techniques
Btec National Diploma Level 3 2
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 3
Hardware tools and techniques
A technician’s toolkit should consist of conventional tools such as:
Screwdrivers and other basic tools Bootable disk Diagnostic hardware Manufacturer’s specifications of hardware
Btec National Diploma Level 3 4
Hardware tools and techniques
Electrical faultsThese faults could lie within a
PSU - power supply unit
Hardware component
Cabling
Connectors
Btec National Diploma Level 3 5
Hardware tools and techniques
What device can be used?
Btec National Diploma Level 3 6
Multi-meter
A 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 7
Hardware tools and techniques
Self test routines
When the computer is switch on the boot process begins (BIOS).
Once BIOS starts to execute the POST process beings.
Btec National Diploma Level 3 8
Hardware tools and techniques
Self test routines Cont.
POST is a hardware diagnostic routine that checks the configuration in CMOS against the actual hardware configuration.
Btec National Diploma Level 3 9
Hardware tools and techniques
Self test routines Cont.
What is CMOS?
COMPLEMENTARY METAL-OXIDE SEMICONDUCTOR
Chip located on the motherboard – holds both the BIOS program and expected hardware configuration details.
Btec National Diploma Level 3 10
Hardware tools and techniques
Monitoring devices
Pinging
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 11
Hardware tools and techniques
Suitable Tools
ESD wrist strap
This is a strap that is connected to the computer’s chassis.
It is used to channel any static electricity away from the technician and to the ground.
Btec National Diploma Level 3 12
Hardware tools and techniques
Suitable Tools Touch Angled mirror – like you would
expect in a dentist Screwdrivers Cleaning materials Wire stripper/cutter Chip tools Paperclip – to test a connection
between one pin to another. Electrical tape
Btec National Diploma Level 3 13
Hardware tools and techniques
Suitable Tools loop-back plug
Can be used to isolate a problem with a port – performs a loop back test.
Btec National Diploma Level 3 14
Software tools and techniques
Diagnostics
Used to examine the computer and it records the
system’s current settings.
Measures the performance of the system
Checks for the presence of viruses
Btec National Diploma Level 3 15
Software tools and techniques
Diagnostics - Examples
BIOS POST SCANDISK AVG - ANTIVIRUS
Btec National Diploma Level 3 16
Software tools and techniques
Monitoring and error loggingMonitoring the computer can make sense of why the performance of the computer has decreased in someway.
Audit trail
Record details about each event that has occurred
Event viewer
Allows you to predict and identify sources of system problems by recording events in three logs based on type of event: security, system and application
Others include: Dr Watson and WinVNC
