It will be case where the "smart battery" (deliberate quotes) is
actually very dumb. For most of the DSDT's I've seen most of these
numbers are hardcoded, and not queried from the battery.

I've even sent the Lenovo BIOS guys a DSDT patch to query the battery
instead of a best guess, but it was ignored. This is why the new g-p-m
code self-profiles, and corrects the values from ACPI.
