Charging The Battery; Maximizing The Battery Life; Managing The Battery Power; Power-Saving Modes - Lenovo ThinkPad T430u User Manual

• You can charge the battery when the ac power adapter is connected to the computer and the battery is
installed. You need to charge it in any of the following conditions:
– When you purchase a new battery
– If the battery meter at the bottom of your display shows the battery charge is low
– If the battery has not been used for a long time

Charging the battery

When you check battery status and find that the percentage of power remaining is low or when the power
alarm alerts you that the remaining power is low, you need to charge your battery.
If an ac outlet is convenient, plug the ac power adapter into it, and then insert the jack into the computer.
The battery will be fully charged in about three hours. This is affected by the battery size and the physical
environment. The Power Manager battery gauge on the task bar will let you know that the battery is
charging, and will also notify you when the battery is fully charged.
Note: To extend battery life, the computer does not start recharging the battery if the remaining power is
greater than 95%.

Maximizing the battery life

To maximize the life of the battery, do the following:
• Use the battery until the charge is completely depleted.
• Recharge the battery completely before using it. The battery is fully charged if the Power Manager battery
gauge on the task bar shows a 100% charge level when the ac power adapter is plugged in.
• Always use power management features such as power modes, screen blank, sleep, and hibernation.

Managing the battery power

With Power Manager, you can adjust your power settings to give you the best balance between performance
and power saving.
For instructions on accessing the Power Manager program, see "Accessing ThinkVantage programs" on
page 13.
