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 com-
puter 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.
Maximizing battery operating time
A battery’s usefulness depends on how long it can supply power on a single
charge.
How long the charge lasts in a battery depends on:
◆ How you configure the computer, for example, whether you enable battery-
power saving options. The computer provides a battery save mode to con-
serve battery power. This mode has the following options:
• Processing speed
• Display auto off
• HDD auto off
• System auto off
• LCD Brightness
