-
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.
-
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
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.
-
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.
-
What tool would you use to troubleshoot a laptop that does not power on and the battery is not charging. You suspect the block on the power cord (Also known as the brick) no longer works.
Multimeter
-
Which tool would you use to remove and replace the motherboard BIOS?
IC Extractor
-
To Prevent ESD when replacing internal computer components, you attach an anti wrist strap to your wrist. Where should the other end be fastened?
- Metal area on the computer
- anti-static mat
-
Your workstation is unable to communicate with any other computer on the network. Which of the following tools should you use to test the ability of the network card to send and receive signals?
Loopback plug
-
A printer is behaving erratically and you suspect a faulty parallel port. Which tool will you use to test the parallel port?
Loopback plug
-
What protects a computer from electrostatic discharge?
Anti-static wrist strap
-
What tool is specifically designed to test the DC current flowing from molex connector?
Power supply teser
-
What tool would you use to retrieve small screws?
Extension magnet
-
What tool would you use to measure electrical properties such as voltage, amps, and resistance?
Multimeter
-
What tool would you use to grab and lift small objects?
3-prong holder
-
You have a network port in an office that connects to the server room using wires strung through the ceiling. Which tool would you use to verify that a signal can be sent from one end to the other.
Cable tester
-
You suspect that the power supply in your desktop PC is failing. You want to use a multimeter to test the power supply. Which multimeter setting should you use?
DC Volts
-
What are the loopback plugs used for?
Testing ports by returning output signals as input.
