Correcting the Battery Display (Battery Recalibration)

The "Battery Recalibration" function measures and memorizes the battery capacity. To correct the battery display, use this
function to fill the battery and then discharge it completely. Perform the procedure at least once immediately after purchasing
the computer. Normally the interval of "Battery Recalibration" is three months. The battery display may not be correct when
the battery pack deteriorates after a long time use. In this case, perform the procedure again.
