Care and use of the battery pack

The Battery indicator may show a rapid decrease in battery operating time when you try to charge a battery under the following conditions:

❑The battery has not been used for a long time.

❑The battery has completely discharged and been left in the computer for a long time.

❑A cool battery is installed in a warm computer.

In such case, follow the steps below.

1.Fully discharge the battery by leaving it in the computer with the power on until the power automatically shuts off.

2.Plug in the AC adaptor.

3.Charge the battery until the Battery indicator glows green.

Repeat the steps two or three times until the battery recovers normal capacity.

Monitoring battery capacity

Remaining battery power can be monitored in the Power Save Modes window in Power Saver of Windows.

NOTES: 1. Wait at least 16 seconds after turning on the computer before trying to monitor the remaining operating time. The computer needs this time to check the battery’s remaining capacity and to calculate the remaining operating time, based on the current power consumption rate and remaining battery capacity. The actual remaining operating time may differ slightly from the calculated time.

2.With repeated discharges and recharges, the battery’s capacity will gradually decrease. Therefore, an often used, older battery will not operate for as long as a new battery even when both are fully charged. In this case, Power Saver Utility will indicate a 100% charge for both the old and new battery, but the displayed estimated time remaining will be shorter for the older battery.
