The battery is nearly completely discharged. In this instance you should leave the AC adaptor connected for a few minutes and the battery should begin charging.

The DC IN/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.

In such cases you should follow the steps as detailed below:

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

2.Connect the AC adaptor to the DC IN 19V jack of the computer, and to a wall outlet that is supplying power.

3.Charge the battery until the DC IN/Battery indicator glows white.

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

Monitoring battery capacity

Remaining battery power can be monitored using the following methods.

Clicking the battery icon on the Windows Taskbar

Via the Battery Status in the Windows Mobility Center window

You should wait at least 16 seconds after turning on the computer before trying to monitor the remaining operating time. This is because the computer needs this time to check the battery's remaining capacity and then calculate the remaining operating time, based on this together with the current power consumption.

Please be aware that the actual remaining operating time may differ slightly from the calculated time.

With repeated discharges and recharges, the battery's capacity will gradually decrease. In view of this it will be noted that an often used, older battery will not operate for as long as a new battery even when both are fully charged.

Maximizing battery operating time

A battery's usefulness depends on how long it can supply power on a single charge, while how long the charge lasts in a battery depends on:

Processor speed

Screen brightness

System Sleep Mode

System Hibernation Mode Display power off period

User's Manual

4-16
