The battery pack has a function for measuring, storing and learning about battery ca-
pacity. Using this function properly to accurately display remaining battery capacity re-
quires that the battery pack be fully charged (charged to 100%), then fully discharged,
and then fully charged again.
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 repeated.
