Detecting that a battery is inside a dock?

Hey,

I have access to a convertible Toshiba machine where the 2nd battery is in detachable keyboard. This is the decompiled DSDT:
https://hadess.fedorapeople.org/toshiba.dsl

There's no BAT0, BAT1 is in the screen, and BAT2 is in the keyboard.

BAT2 can be ejected (it has an _EJD method), but the dock code doesn't
see it as having a battery:

$ pwd
/sys/devices/platform/dock.0
$ cat flags
16
$ cat type
dock_station

Any ideas what might be missing here?

I'd eventually like to be able to say that, if I can detect that the battery is inside the dock, to mark it as such in the UI[1] (even better would be to say it's "in the keyboard" but I'm not sure we can
easily detect that).

Not now, sorry. Too many things are going on in parallel and this one is
not the most urgent of them.

Please file a bug for it at bugzilla.kernel.org in the ACPI category, so it's
not forgotten. Those bugs are looked at on a regular basis, so we'll get to
it at one point.

Sure. I didn't expect a bug fix straight away, I just wanted to know whether I was missing something.
