The following devices and components are used for computer repair and maintenance:
|Combination ratchet/screwdriver||A combination ratchet has interchangeable bits with a ratcheting handle that provides multiple features in a single tool.
|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:
|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||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.|
|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:
