My X240 drains the external battery to 5% and then switches to the
internal battery.  When charging, the internal battery is charged first
until it reaches 80%, then the external battery is charged, and after
that, the internal battery is charged the remaining 20%.

So I=E2=80=99m not sure what you mean by =E2=80=9Cbattery balancing=E2=80=
=9D, but my X240
doesn=E2=80=99t drain the external battery down to 0%.  I=E2=80=99m actuall=
y quite
pleased with the way it drains and charges the batteries.
