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 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.
