Combination ratchet/screwdriver
A combination ratchet has interchangeable bits with a ratcheting handle that provides multiple features in a single tool.
  • Bit ends can be replaced for phillips and flat head screwdrivers, hex sockets, and torx (star-shaped) bits.
  • The ratcheting handle allows you to drive the screw without repositioning the driver.
Most computer components use phillips head screws.
IC insertion/extraction tool
Use an IC insertion/extraction tool to easily add or remove integrated circuit chips that are used on motherboard and some computer components. For example, on some motherboards you can use the IC insertion/extraction tool to change the BIOS chip.
Anti-static pad/wrist strap
An anti-static pad provides an insulated covering to prevent static electricity from moving between objects and damaging computer components. When working with computer components, use a wrist strap connected to the anti-static pad, and connect the pad to a ground.
Extension magnet
An extension magnet is a small magnet on a collapsible rod. Use the extension magnet to retrieve screws that have fallen into a computer case or other areas you cannot reach. As an alternative to a magnet, use an extension tool with retractable prongs.
Multimeter
A multimeter is a device for testing various electrical properties. For example, most multimeters can measure:
  • AC and DC voltage
  • Current (amps)
  • Resistance (ohms)
  • Capacitance
  • Frequency
Power supply tester
A power supply tester is a custom multimeter that is used for testing output from a PC power supply. The power supply tester has multiple connectors to test the output for each connector type.   It's specifically designed to test DC current flowing from the brick of a power supply.
Cable tester
A cable tester verifies that a network can carry a signal from one end to the other, and that all wires within the connector are in their correct positions. Most testers have a single unit that tests both ends of the cable at once. Many testers come with a second unit that you can plug into one end of a long cable run to test the entire cable.
Loopback plug
A loopback plug is used to test network communications by redirecting a signal from the transmit port on a device to the receive port on the same device. Use the loopback plug to verify that a device can both send and receive signals. Loopback plugs are used to test serial and parallel ports.
Known good spares
One valuable troubleshooting method is to keep a set of components that you know are in proper functioning order. If you suspect a problem in a component, swap it with the known good component. If the problem is not resolved, troubleshoot other components. Examples of using this strategy are:
  • Changing the cable connecting a computer to the network.
  • Connecting a different monitor to a computer.
  • Replacing an expansion card.
Ammeter
Is an instrument that measures the flow of electric current in a circuit.
3-prong holder
A tweezer like tool with 3 prongs used for grabbing and lifting small objects.
Mini electric combination set
A set of standard wrenches which are designed in size and thickness to be used on electronic components.
Crimper
(with an interchangeable die is a crimping tool with multiple dies for crimping different wiring configurations.
When working with computer hardware, what is the advantage of having a ratcheting handle on a screwdriver?
 
It allows you to drive the screw without repositioning the driver.
What is a good tool to use to retrieve a screw that has fallen into the computer case?
Extension magnet
  1. What types of electrical properties can a multimeter measure?
  1. Voltage - a measurement of electrical potential
  2. Ohms - a measure of resistance
  3. Current flow - the number of electrons crossing a cable
  4. Capacitance - the ability of a component to retain a charge when the power is turned off.
  5. Continuity - the connection made between one end of the cable and the other
How is a power supply tester used to test the output from a PC power supply?
It's used to test the correct voltages coming out of your system's power supply.
  1. How does a loopback plug verify that a device can both send and receive signals?
  1. How can ESD damage computer components?
What measures should you take to protect hardware against ESD damage?
Wear an ESD wrist band. Put components in special ESD bags while
