I agree with you all that it's a fuse, and now my laptop starts without a battery where previously it did not. I don't know what changed; did I shift a broken joint? Did I displace a dark spirit from its residence? I don't know.
It still doesn't start or charge when the battery is connected. It turns on for a second or two, then goes off. The battery is "new", but discharged from the last time I tried this.

@Unixbigot@aus.social @xssfox@cloudisland.nz @LapTop006@aus.social : The symptoms leading up to this was it randomly switching to battery even when plugged in, until eventually it wouldn't accept jack power at all, even with the battery unplugged.
So that sure sounds like a problem with the power bits, but I'm not precisely sure what.
