Sources that can help you with hardware troubleshooting include the user manual, the Internet, online technical support, technical forums, diagnostic software and your network of technical associates. In which order would you proceed to diagnose and resolve a particular hardware issue? What are the advantages and disadvantages of each method?
During hardware troubleshooting, I believe the first and most important thing an engineer should be doing is observation. Check for any obvious issues visually tracked and collect information regarding the issue. Some computers may be difficult to open, or have steps to extract a part from the hardware. It is always important to read the manual to know how to do physical operation on a hardware you have not dealt before. You might destroy a part of the hardware without knowing. As for collecting information on a system, the best way to find out a hardware issue is from conducting a hardware diagnostics. It is important to do so at first since you can verify that there is a hardware issue and know which parts are faulty. You would eventually be wasting time for the client and the company. The disadvantage is that it takes at least 15 minutes to 30 minutes to do a hardware diagnostics on a system. Not a very effective method in a timely troubleshooting situation. During the hardware diagnostics, looking up the particular issue it have over the internet would be a good idea. Internet is a very quick and good solution to lookup through wide range of information. The disadvantage of looking up troubleshooting issues over the internet is that it doesn’t always give you the right answer. The less information you have about the issue the worse. “It involves bringing together resources to investigate the possible root causes of the failures and pulling together enough information to propose potentially permanent resolutions” (Hobbs, 2011) It is important in troubleshooting to get it right the first time. The last step in my troubleshooting step would be calling for technical support. They would although ask you to do the hardware diagnostic either way and will ask to do some basic physical troubleshooting. You would certainly get the right answer and would be able to arrange a RMA if the hardware is still under warranty.
