CompTIA A+ professionals should have all the essential tools to help them effectively diagnose and resolve computer-related issues. These tools can include both physical tools and software applications.

Tools for the Job

Here’s a list of essential tools for an A+ professional:


A set of precision screwdrivers, including Phillips and flathead, is essential for opening computer cases and working with internal components.

Anti-static Wrist Strap:

To prevent electrostatic discharge (ESD) that can damage sensitive computer components, wear an anti-static wrist strap while working on computers.


A small, powerful flashlight can help you see inside dark computer cases and work in low-light environments.

Digital Multimeter:

This tool is crucial for testing power supplies, troubleshooting electrical issues, and checking voltage and resistance.

Cable Tester:

A cable tester is used to verify the integrity of network cables, helping you identify and fix connectivity problems.

Crimper and Cable Connectors:

These are necessary for creating or repairing Ethernet cables.

Needle-Nose Pliers and Tweezers:

Useful for handling small parts and making precision adjustments.

SATA/IDE to USB Adapter:

Allows you to connect internal hard drives or optical drives externally, making data recovery and backup easier.

USB Drive with Portable Tools:

Load a USB drive with diagnostic and troubleshooting software like Hiren’s BootCD, Ultimate Boot CD, and antivirus tools.

Operating System Installation Media:

Keep installation discs or USB drives for various operating systems (Windows, Linux, macOS) for reinstalling or repairing OS issues.

Diagnostic Software:

Tools like Memtest86, CrystalDiskInfo, and CPU-Z can help diagnose and test hardware components.

Bootable USB Drive:

Create a bootable USB drive with various operating systems and utilities for system recovery and troubleshooting.

Compressed Air Canister:

Use this to blow dust and debris out of computer cases, which can help prevent overheating and improve performance.

Ethernet Cable:

Having an Ethernet cable on hand can be helpful for quickly testing network connectivity.

Power Supply Tester:

This tool helps you check the health of power supplies and determine if they are causing issues.

External Hard Drive:

Useful for backing up data and transferring files when dealing with faulty internal drives.

Labeling Equipment:

Keep labels and a label maker for organizing cables and components. Proper labeling can save time and prevent confusion.

Cable Ties and Velcro Straps:

These are essential for cable management to maintain a tidy and well-organized system.

ESD Bags:

These are useful for safely storing and transporting sensitive computer components.

A Toolkit:

A toolkit with a variety of compartments for organizing and carrying your tools is essential.

Maintenance Tools
