Troubleshooting Flashcards
Antistatic Bag
A bag typically made of plastic polyethylene terephthalate used to store components that are sensitive to electrostatic discharge.
ESD MAT
An electrically grounded mat designed to place computer equipment on while a person is working.
ESD Strap
A device worn by the user on their wrist, ankle, or heel and then attached to a ground source away from sensitive internal components.
Faraday Cage
An enclosure that protects the components from any electrostatic discharges that occur outside the antistatic bag.
Self-grounding
A situation where you touch a grounded metal object, such as the computer’s chasis, prior to working on sensitive components.
Troubleshooting
A process of identifying and resolving issues within a computer system.
CRT displays
Contain leaded glass, which if broken can cause soil and water contamination.
Batteries
Include heavy metals, which if sent to landfill can cause soil and groundwater pollution.
Printer cartridges
Include a complex combination of plastics, metals, foam, ink, and toner which are not biodegradable.
You have confirmed the cause and established a plan of action to resolve the problem, what will you do next?
Take steps to implement the solution.
Why is it a bad idea to simply correct a problem based on its symptoms?
If you treat the symptoms of a problem without understanding its true cause, it’s likely to recur or cause other issues you haven’t noticed yet.
What communication problems have you had during the troubleshooting process in the past, either when seeking help from a technician or when trying to assist someone else?
Answers may vary. Likely problems include inexact description of symptoms, losing track of what changes have been made already, and difficulty reproducing problems.
What safety hazards are there in your workplace?
Answers may vary, but almost every workplace has potential electrical and tripping hazards as well as some heavy equipment.
What safety equipment have you used to protect yourself or valuable equipment?
Answers may vary. If you’re not familiar with ESD protection, you should practice it.
What is any data that could potentially be used to identify a particular person?
PII
How will you protect your equipment if you don’t have an ESD device while working?
By using self-grounding technique
What is the A+ Troubleshooting Process?
- Identify the problem.
- Establish a theory of probable cause.
- Test the theory to determine cause.
- Establish a plan of action and implement the solution.
- Verify system function.
- Document findings.
What is the A+ Computer/Device disassembly process?
- Document and label-cable and screw locations.
- Organize your parts.
- use the appropriate tools
- Refer to manufacturer resources.
What are the personal guidelines to prevent injury?
- Disconnect the power before repairing a computer or other device.
- Remove loose items such as jewellery, scarves, or ties that could get caught or bang on components.
- Use proper lifting techniques when moving heavy equipment.
- Be aware of weight limitations.
- Be prepared for electrical fires.
- Secure loose cables out of the way.
- Wear safety goggles.
- Wear an air filter mask.
What items that should be recycled not binned?
- Batteries
- Toner Cartridges
- CRT Displays
- Cell phones and tablets often contain toxic materials including non-removable batteries
What are the guidelines for providing professional services to the customers?
- Be on time.
- Maintain a positive attitude and project confidence.
- Be culturally sensitive.
- Set achievable expectations for service activities and their timeline.
- Use proper language.
In the CompTIA troubleshooting method, the final step is to document your findings, actions, and outcomes.
