5. Refresh Battery

The battery pack has a function for measuring, storing, and learning about battery capacity. Using this function
properly to accurately display remaining battery capacity requires that the battery 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 battery deterioration and other factors.
If this is the case, the procedure described below should be performed again.
