A1707 (and similar) Battery-PCB contact assembly failure rates?

[Paul Daniels]

An A1707 in today, more time spent trying to get that bottom panel off than what happened next.

Machine booted fine, battery detected, 0% and no lightning/charging going on according to the macOS.

Undid the connectors, flipped up the +/- tang, appeared clean, put it back together and now it's working fine and charging up from 1~2%.

Is this something that we should expect to see more of? Is it because of the rather interesting non-cleaning/surface-contact-only +/- pads being used, or was this possibly the data FPC cable perhaps not sitting right (I would have erred to the battery contacts since the battery was being detected).

You could've done a SMC reset on the keyboard too, would have had the same result. Left shift+alt+cmd+power button.

What's causing the original issue and why does the SMC reset resolve the issue, and I suppose more crucially, will it be an issue that recurs ?

No idea, the SMC runs firmware so it can mess up, it happens. Can you really expect the SMC to run for 5 years without a hiccup?
