Discuss any five guidelines that we need to follow while troubleshooting the hardware problem.
Answers
Some things to keep in mind while troubleshooting a hardware problem are:
1. Check the cables - If you have trouble with a particular piece of computer hardware like the monitor or keyboard check if all the cables are connected properly.
2. Restart the computer - Restarting the computer can solve a number of basic computer problems.
3. Note the error messages - If the computer gives an error message write down all the information that is given in it. You can use this information to find the remedy from other people who get the same error message.
4. Write down the steps you take to rectify the problem - Write down all the steps you take while troubleshooting. This will help you to remember what you have done. You can avoid making the same mistakes. It will also be useful when you take help from others. They will know exactly what you have done already.
5. Use the process of elimination - Make a list of things that could be causing the problem. Then test them one by one and eliminate them. In this way you can identify the source of the problem.
We can follow the following guidelines.
Verify that a problem actually exists: Even a novice will know whether the problem is a hardware or software problem. There are some testing processes which can verify that there is a problem. For example, the hardware testing can be done by pressing enter key before the computer gets logged in. In case of MAC, it will be different.Identify the cause of the problem: For example, you would have dropped your machine or a virus could have attacked or excess passing of power flow could have been the reason
Correct the cause of the problem: If possible, the cause of the problem could be corrected. But, the problem created in the machine should be corrected immediately.
Verify that the problem has been corrected: After the problem is corrected, thorough checking is needed. We can allow the machine to work for long hours and check whether the problem is occurring or not.
Follow up to prevent future problems: We need to get the information from the service engineer as to how to prevent any future occurrence of the problem and follow it strictly.
