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 recal-
ibration is 3 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.

tery pack), the battery recalibration will not be completed.

The battery recalibration may take a long time due to the large battery capacity. This is not a malfunction. (An expected approximate
recalibration time is displayed.)

<Only for model with Built-in Bridge Battery>
The battery recalibration cannot be performed for the built-in bridge battery.
