> The battery swelling happened after the other issues (like not sitting flat on the desk).
I had 2 x86 MacBooks that had issues with batteries swelling. Not sitting flat on the desk is simply the first symptom of the problem. Once it swells up a bit more the keyboard starts to show problems.
I think the main issue with those machines was thermal management. That Intel chip got too hot and that affected the battery as well. I used mine quite intensively and they regularly ran hot even with the fans running full speed.
