In this sample chapter from IT Essentials Companion Guide v7 for Cisco Networking Academy, you will learn about the many benefits of conducting preventive maintenance for both hardware and software. IT Essentials Companion Guide v7. Troubleshooting is a systematic process used to locate the cause of a fault in a computer system and correct the relevant hardware and software issues. Approaching problem solving using a logical and methodical approach is essential to successful resolution.
Although experience is very useful to problem solving, following a troubleshooting model will enhance effectiveness and speed. In this section, you will learn that to troubleshoot a problem quickly and effectively, you need to understand how to approach the issue.
Troubleshooting is a way of discovering what is causing a problem and fixing it. Troubleshooting requires an organized and logical approach to problems with computers and other components. Sometimes issues arise during preventive maintenance. At other times, customers may contact you with problems. Taking a logical approach to troubleshooting allows you to eliminate variables and identify causes of problems in a systematic order.
Asking the right questions, testing the right hardware, and examining the right data helps you understand the problem and form a proposed solution. Troubleshooting is a skill that you refine over time.
Each time you solve a problem, you increase your troubleshooting skills by gaining more experience. You learn how and when to combine steps, or skip steps, to reach a solution quickly. The troubleshooting process is a guideline that is modified to fit your needs. This section presents an approach to problem solving that you can apply to both hardware and software.
The term customer , as used in this book, refers to any user who requires technical computer assistance. Before you begin troubleshooting problems, always follow the necessary precautions to protect data on a computer. Some repairs, such as replacing a hard drive or reinstalling an operating system, might put the data on the computer at risk.
Make sure you do everything possible to prevent data loss while attempting repairs. If your work results in data loss for the customer, you or your company could be held liable. A data backup is a copy of the data on a computer hard drive that is saved to another storage device or to cloud storage.
Cloud storage is online storage that is accessed via the Internet. In an organization, backups may be performed on a daily, weekly, or monthly basis. If you are unsure about whether a backup has been done, do not attempt any troubleshooting activities until you check with the customer.
Here is a list of items to verify with the customer regarding whether a backup has been performed:. If the customer does not have a current backup and you are not able to create one, ask the customer to sign a liability release form. A liability release form contains at least the following information:.
The troubleshooting process steps are as follows:. Step 4. Establish a plan of action to resolve the problem and implement the solution. Step 5. Verify full system functionality and, if applicable, implement preventive measures. The first step in the troubleshooting process is to identify the problem. During this step, gather as much information as possible from the customer and from the computer. Open-ended questions allow customers to explain the details of the problem in their own words.
Use open-ended questions to obtain general information. Based on the information from the customer, you can proceed with closed-ended questions. A closed-ended questions generally requires a yes or no answer. Document the information from the customer in the work order, in the repair log, and in your repair journal.
Write down anything that you think might be important for you or another technician. The small details often lead to the solution of a difficult or complicated problem. Each BIOS manufacturer has a unique beep sequence, a combination of long and short beeps, for hardware failures. When troubleshooting, power on the computer and listen. As the system proceeds through the POST, most computers emit one beep to indicate that the system is booting properly. If there is an error, you might hear multiple beeps.
Document the beep code sequence and research the code to determine the specific problem. A device might not be detected or configured properly. Refer to the motherboard documentation to ensure that the BIOS settings are correct. When system, user, or software errors occur on a computer running Windows, the Event Viewer is updated with information about the errors. The Event Viewer , shown in Figure , records the following information about the problem:. Figure Event Viewer. Although the Event Viewer lists details about an error, you might need to further research the problem to determine a solution.
The Device Manager , shown in Figure , displays all the devices that are configured on a computer. The operating system flags the devices that are not operating correctly with an error icon. A yellow triangle with an exclamation point indicates that the device is in a problem state. An downward-pointing arrow means the device has been disabled. A yellow question mark indicates that the system does not know which driver to install for the hardware. Figure Device Manager.
The Task Manager , shown in Figure , displays the applications and background processes that are currently running. With the Task Manager, you can close applications that have stopped responding. You can also monitor the performance of the CPU and virtual memory, view all processes that are currently running, and view information about the network connections. Figure Task Manager. Conduct research to determine what software is available to help diagnose and solve problems.
Many programs can help you troubleshoot hardware. Manufacturers of system hardware usually provide diagnostic tools of their own. For instance, a hard drive manufacturer might provide a tool to boot the computer and diagnose why the hard drive does not start the operating system.
The second step in the troubleshooting process is to establish a theory of probable cause. First, create a list of the most common reasons for the error. Even if the customer thinks there is a major problem, start with the obvious issues before moving to more complex diagnoses, as outlined here:. List the easiest or most obvious causes at the top.
List the more complex causes at the bottom. If necessary, conduct internal logs, journal or external internet research based on the symptoms. The next steps of the troubleshooting process involve testing each possible cause.
You can determine an exact cause by testing your theories of probable causes one at a time, starting with the quickest and easiest. Some common steps to determine the cause of the problem are as follows:. Once the theory is confirmed, you can determine the steps to resolve the problem. As you become more experienced at troubleshooting computers, you will work through the steps in the process faster. For now, practice each step to better understand the troubleshooting process. If you cannot determine the exact cause of a problem after testing all your theories, establish a new theory of probable cause and test it.
If necessary, escalate the problem to a technician with more experience. Before you escalate, document each test that you tried, as shown in Figure Figure Work Order.
After you have determined the exact cause of the problem, establish a plan of action to resolve the problem and implement the solution. Sometimes quick procedures can correct the problem. If a quick procedure does correct the problem, verify full system functionality and, if applicable, implement preventive measures.
If a quick procedure does not correct the problem, research the problem further and then return to Step 2 to establish a new theory of the probable cause. After you have established a plan of action, you should research possible solutions such as the following:.
Divide large problems into smaller problems that can be analyzed and solved individually. Prioritize solutions starting with the easiest and fastest to implement.
Create a list of possible solutions and implement them one at a time. If you implement a possible solution and it does not correct the problem, reverse the action you just took and then try another solution. Continue this process until you have found the appropriate solution. After the repairs to the computer have been completed, continue the troubleshooting process by verifying full system functionality and implementing the preventive measures needed, as outlined here:.
Verifying full system functionality confirms that you have solved the original problem and ensures that you have not created another problem while repairing the computer. Whenever possible, have the customer verify the solution and system functionality. After the repairs to the computer have been completed, finish the troubleshooting process with the customer.

Это были ее первые слова за очень долгое время. Сьюзан подняла голову. Глаза ее были затуманены. - Танкадо успел отдать его за мгновение до смерти.
- Я ошиблась. - Она сдвинула брови, задумавшись, почему ТРАНСТЕКСТ за весь день не взломал ни единого шифра. - Позволь мне кое-что проверить, - сказала она, перелистывая отчет.
Если Дэвид и дальше задержится, придется послать ему на помощь кого-то из полевых агентов АНБ, а это было связано с риском, которого коммандер всеми силами хотел избежать. - Коммандер, - сказал Чатрукьян, - я уверен, что нам надо проверить… - Подождите минутку, - сказал Стратмор в трубку, извинившись перед собеседником. Он прикрыл микрофон телефона рукой и гневно посмотрел на своего молодого сотрудника.
Оказавшись в условиях подлинного разведывательного затемнения, АНБ выпустило секретную директиву, одобренную президентом Соединенных Штатов. Заручившись поддержкой федеральных фондов и получив карт-бланш на все необходимые меры для решения проблемы, АНБ приступило к созданию невозможного - первой универсальной машины для вскрытия шифров. Вопреки широко распространенному мнению о том, что такой компьютер создать невозможно, АНБ осталось верным своему девизу: возможно все; на невозможное просто требуется больше времени.
