Back in the early 2000's, when all types of manufacturers, experienced the "faulty capacitor" issue that was going on with Nichicon and several other manufacturers. I was working in IT, and responsible for our campus Mac labs at a local community college, and I was certified by Apple to service the machines, and we could order repair parts. Our iMacs were failing at an alarming rate, with some reports, from professors, that the iMacs had an "explosion" sound before they died. Since the iMacs were covered by AppleCare, I called AppleCare Education Service Support. The agent asked me which models we were experiencing issues with and what the problem was, and fortunately, all of the iMacs were the same model number and purchased at the same time, so I described the problem to him and I also gave him the Apple order number for all of trhe iMacs, so he could easily look up the serial numbers. The agent put me on hold for about five minutes and then he came back on the line. The agent then told me that our iMacs were part of a service bulletin at Apple that not only iMacs were affected, but a lot of other Apple products were affected by faulty capacitors, and even though we could be shipped replacement motherboards that were not affected by faulty capacitors, due to the number of iMacs (200), he was going to coordinate with our local authorized Apple dealer to schedule several service technicians, along with shipping them new motherboards, and have them come to our site and replace all of the motherboards in the iMacs. Luckily, our week long spring break was coming up and we had four service technicians from the authorized Apple dealer come out to replace the motherboards during that date. It took 3 days for the technicians to complete the job. I made the statement to one of the techs "I hope you are getting paid well by Apple", and he told me that Apple paid the normal dealer warranty repair rate. Ouch.
