Why the problem was not properly diagnosed The technician responsible came out, and we were able to solve the mystery. However, what hadn’t been done was to startup or wake the machine on battery, as that’s what resulted in an instant shutdown when the machine was brought in and still resulted in an instant shutdown when I tested it on collection. This is what is supposed to be a real-life test: starting up and then running some software to ensure that trackpad, keyboard, microphone, speakers, and so on, were all working. It also showed that a ‘functional test’ had been performed. The records showed that it had been put through all the automated tests, and had passed all of them. My immediate reaction was frustration at the fact that it appeared nobody had carried out a real-life test of the machine. The bad news, however, was that the machine still immediately shutdown when run on battery power… It had a shiny new keyboard, and non-swollen battery. There was some good news when I went to collect my MacBook Pro today: the top-case replacement had been done. To add to the faulty keyboard and swollen battery, it turns out my MacBook Pro has a third failure: a logic board fault.
