When I came back from holiday I forgot that I had unplugged several
items from one of the multi-way mains boards that includes the power
supply for my MacBook. I went on using the MacBook for a while,
oblivious of the fact that it was running on batteries until something
went "Plink!" and it switched off.

The "Plink" sound was quite metallic, like the diaphragm in a heavy-duty
thermal switch, but I can't think of anything in the MacBook that would
make such a noise. It seemed to come from the back R.H. corner.

The only explanation I can think of is that the screen-power inverter
momentarily froze in one half-cycle and saturated the ferrite core, the
sound being caused by magnetostriction. Does anyone have any other
suggestions?

I couldn't guess. Maybe the sound of its soul leaving its body?

Did it work when you plugged it in again though?

Yes, it charged up again and ia working now. The battery is beginning
to swell, so I suppose I should be budgeting for a new one

Try to ask nicely first.
I had a swelling battery in a 2017 MBP that was replaced at no cost.

I'm pretty sure Rog had a swollen one that was replaced by Apple way out of
warranty too.
