I have had many people over the years complain to me about computer repair shop problems. There are industry certifications for computer repair, but there isn’t any law requiring companies to have these certifications or actually any training at all. There have been a couple of recent and interesting studies done evaluating computer repair companies.
In one such study a reporter unplugged the power to the hard drive from the power supply inside the computer. Fixing this would take less than 1 min. Several computer repair specialist were called to diagnose and fix the problem. About half of the individuals called were able to fix it for the minimum one-hour site visit charge. The other half either charged more, or had to take the computer back to their shop. Some of the technicians that took the computer back to the shop required that more hardware be purchased and one of them totaled more than $250 in additional hardware to fix the problem.
Another recent study took 18 computer stores, some large corporations like Best Buy and CompUSA and others were small mom and pop computer stores and gave them a total of 31 common and simple computer problems. Surprisingly, the computer repair shops could not solve 18 of the 31 problems. Of those 18 stores, only 7 stores were able to properly diagnose a bad hard drive cable. 8 of the 18 shops advised the computer owner to replace perfectly good parts averaging $340 in useless repairs.
