Combination ratchet/screwdriver

  [image]

It 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

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

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

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

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

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.

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.

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.

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.
