I had tested my serial number back when they announced it and mine is not affected (a Spanish model), which makes me wonder: how come only a range of models are affected? Aren't they all built in the same way? Just wondering if I'll eventually face that issue a few years down the line, now I get paranoid anytime I leave my laptop alone on my wooden desk.

> how come only a range of models are affected? Aren't they all built in the same way? Most manufacturers will dual-source component suppliers (because a) it can drive your costs down, and b) you're not reliant on a single company to supply you), so it's very easy to have some models impacted but not others. Even with a single supplier you can have bad batches of raw materials, a single factory line with an assembly defect, or the QA team just happened to all be out sick one day.

They're built the same way with interchangable components. But device manufacturers at large scale get multiple suppliers to supply their components. As long as it meets specification it can be used.

In principle yes, but manufacturing is a complicated process involving many suppliers, potentially different ones for the same part. From my experience: it is mostly a component from a certain batch/certain manufacturer that was not working correctly. This information which part was used is stored somewhere and thus it makes sense to check on through the serial number.

Yep. I wonder similar about the 13" MBP 2015 that I have, which has a swollen case. Not covered in last year's 13" recall, but looks like the same problem. The London Apple store disagree :(

  Same laptop, same issue about a year ago. I had it checked out at a local Apple Authorized Service Provider, they ended up replacing the battery (for the usual battery replacement fee).
