Okay, I spoke too soon. The problem is back. I don't know what I did that made it work briefly, or what I did to make it broken again.
I have experimented by letting my battery discharge and recharge, putting the AC power in and out and so on to see if I can find what fixed it temporarily, but I can't reproduce the fixed state.

I'm happy to investigate if anyone has any ideas.
