Dust may not be the real issue behind butterfly keyboards failing

by Volker Weber

Today we will be tearing down a MacBook Pro keyboard to try and see if we can rule out dust as a possible cause. Settle down, because this will be a bit of a long post. Hopefully you'll at least learn something from this.

Disclaimer: This post is not meant to answer why keyboards fail. That is beyond me and I can only offer theories. My goal is only to disprove the idea that dust causes no-input and multi-input style failures.

This is a very long post. Spoiler: If you type a lot on your butterfly keyboard, it is very likely to fail eventually. And that explains why so many writers have issues. They just use it more than the average person.

It's odd to live in a world where Lenovo, Microsoft, and HP build the best and most interesting laptops.

The main thing I get from the article is that the problems are more related to heat/cold cycles and being used than dust related.

That said, I do not envy the designer who has to create a thin and reliable keyboard for millions of users in all the varying climates.
