The battery pack has a function for measuring, storing and learning about battery capacity.
Using the "Battery Recalibration" function to accurately display remaining battery capacity
requires that the battery pack be fully charged (charged to 100%), then fully discharged. This
procedure should be performed once after you purchase the computer. As you use the
battery pack over a long period of time, the remaining capacity display may become
inaccurate due to aging of the battery pack and other factors. The procedure described
below should be performed again.
