Hmm, I switched to RELENG_9 shortly before the 9.0 release. It had
worked then, or I'd have PRed a regression.
It stopped working around the beginning of this FSAE season. Probably
between September and December.

This is from the verbose dmesg:
# dmesg | grep -i bat
battery0: <ACPI Control Method Battery> on acpi0
battery1: <ACPI Control Method Battery> on acpi0
battery0: battery initialization start
battery1: battery initialization start
battery0: battery initialization done, tried 1 times
battery1: battery initialization failed, giving up
Looks right to me. Greping for acpi or fail doesn't yield anything
interesting.
There is a bunch of errors during shutdown, I have a dmesg with verbose
boot, shutdown and normal boot prepared, for whoever wants to look at it.

Yes, it's wrong. There is an option to swap out the optical drive for a
battery, I think. But I still have my optical drive.
