Public bug reported:
I have a lenovo w520 with a secondary battery attached simultaneously.
When booting with both batteries, the power-statistics only sees the
first battery even though power is always drained from the second
battery first. Flipping the locking switch that holds the external
battery on to the bottom re-establishes the connection and the computer
recognizes the battery is attached. If I ignore this action, the power
monitor will think that the computer is using so many watts without the
battery percentage of the first battery changing. The result is that
"discharge accuracy" will produce an ever growing "correction factor" at
whatever percentage the primary battery has already had.
