Hand Tools (2.2.1.3)
Most tools used in the computer assembly process are small hand tools. They are available individually or as part of a computer repair toolkit. Toolkits range widely in size, quality, and price. Some common hand tools and their uses are:
Flat-head screwdriver: Used to tighten or loosen slotted screws.
Phillips-head screwdriver: Used to tighten or loosen cross-headed screws.
Torx screwdriver: Used to tighten or loosen screws that have a star-like depression on the top, a feature that is mainly found on laptops.
Hex driver: Used to tighten or loosen nuts in the same way that a screwdriver tightens or loosens screws (sometimes called a nut driver).
Needle-nose pliers: Used to hold small parts.
Wire cutters: Used to strip and cut wires.
Tweezers: Used to manipulate small parts.
Part retriever: Used to retrieve parts from locations that are too small for your hand to fit.
Flashlight: Used to light up areas that you cannot see well.
Wire stripper: A wire stripper is used to remove the insulation from wire so that it can be twisted to other wires or crimped to connectors to make a cable.
Crimper: Used to attach connectors to wires.
Punch-down tool: Used to terminate wire into termination blocks. Some cable connectors must be connected to cables using a punch down tool.
Cleaning Tools (2.2.1.4)
Having the appropriate cleaning tools is essential when maintaining and repairing computers. Using the appropriate cleaning tools helps ensure that computer components are not damaged during cleaning. Cleaning tools include the following:
Soft cloth: Used to clean different computer components without scratching or leaving debris
Compressed air: Used to blow away dust and debris from different computer parts without touching the components
Cable ties: Used to bundle cables neatly inside and outside of a computer
Parts organizer: Used to hold screws, jumpers, fasteners, and other small parts and prevents them from getting mixed together
Diagnostic Tools (2.2.1.5)
Diagnostic tools are used to test and diagnose equipment. Diagnostic tools include the following:
A digital multimeter, as shown in Figure 2-3, is a device that can take many types of measurements. It tests the integrity of circuits and the quality of electricity in computer components. A digital multimeter displays the information on an LCD or LED.

A loopback adapter, also called a loopback plug, tests the basic functionality of computer ports. The adapter is specific to the port that you want to test.
The toner probe, as shown in Figure 2-4, is a two-part tool. The toner part is connected to a cable at one end using specific adapters, such as an RJ-45, coaxial, or metal clips. The toner generates a tone that travels the length of the cable. The probe part traces the cable. When the probe is in near proximity to the cable to which the toner is attached, the tone can be heard through a speaker in the probe.
