Maximizing battery life

To maximize the life of the battery, do the following:

•Use the battery until the charge is completely depleted; that is, use the battery until the battery status indicator starts blinking orange.

•Recharge the battery completely before using it. The battery is fully charged if the battery indicator shows green when the ac power adapter is plugged in.

•Always use power management features such as power modes, screen blank, sleep, and hibernation.

Managing your 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 14.

For more information about the Power Manager program, refer to the help information system.

Power-saving modes

There are several modes that you can use at any time to conserve power. This section introduces each mode and gives tips on the effective use of the battery power.

Introducing the power-saving modes

•Screen blank.

The computer display requires considerable battery power. To turn off power to the display, do the following:

1.Right-click the Power Manager battery gauge on the taskbar.

2.Select Power off display.

•Sleep

In sleep mode, your work is saved to memory, and then the solid state drive or the hard disk drive and the computer display are turned off. When your computer wakes up, your work is restored within seconds.

To put your computer into sleep mode, press Fn+F4. To return from sleep mode, press the Fn key.

Depending on the computer model, your computer might support the 30 Day Standby function. When this function is enabled, the computer consumes even less power in the sleep mode and takes only seconds to resume normal operation when you press the Power button. To enable the 30 Day Standby function, do the following:

1.Start the Power Manager program and switch to the advanced view.

2.Click the Global Power Settings tab and select Enable 30 Day Standby.

3.Click Apply. The 30 Day Standby function will take effect the next time you start your computer.

For more information about the 30 Day Standby function, refer to the help information system of the Power Manager program.

You also can use the combination to put the computer into hibernation mode by changing the settings in the Power Manager program.

•Hibernation.

By using this mode, you can turn off your computer completely without saving files or exiting from any applications that are running. When you enter hibernation mode, all open applications, folders, and files are saved to the hard disk, and then the computer turns off.
