If it was that easy, somehow I get the impression that Amazon was employing software engineers to investigate the trouble, not electrical engineers. Big difference.
This. If I'd known about the full context of the issue my first thought would have been to take it down to the EE lab and do exactly what he did.
I suspect the issue was more that very few people knew all of the pieces of the puzzle, not that nobody was smart enough to put them together. This is pretty basic stuff (which in turn means that Amazon should be pretty ashamed that it happened).
Except since the guy did it at home, he hadnt sent it back, therfore whoever was looking into it may well have had amazons own ones there, which may not have been chipped.
The real mistake here was QA probably only tested the light based one electronically in lifetime tests, the basic cheaper one doesnt have any electrical issues to go wrong the thinking probably thought, so to save time and money. Sounds likely to be the QA management trying the hardest part of engineering, working to cost, and so chose to cut out a test regime that doenst seem nessery.
The irony is the lighted cover would have had such testing performed, including wear on its connections, affecting conduction.
