Following up on this, as I've had no replies.
I replaced the factory-installed battery with a new, Lenovo-branded one.
Nothing's changed. When running Fedora 32, I still hear the
click-CLICK and CLICK-click when power switches from wallplug to battery
and back again as the laptop moves around a bit in my lap.
Booted in Windows 10, I see the on-off pattern with the on-screen
battery icon, but don't hear the clicks.
