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.

1.Connect the AC adaptor.

2.Close all the applications.

3.Perform "Battery Recalibration".

1.Click (Start)*7 - [All Programs] - [Panasonic] - [Battery] - [Battery Recalibration].

2.When the confirmation message appears, click [Start].

Frequent recalibration of the battery can degrade the battery. A caution message appears when the battery recalibration is performed at the shorter interval than approximately a month. In this case, cancel the battery recalibration.

3.When the message requests shut down of Windows, click [Yes]. The battery recalibration starts.

After the battery pack is fully charged, discharging starts. When the discharging is completed, the power goes off automatically.

After the battery recalibration is finished, normal charging starts.
