Power Management

Understanding Power Consumption

In order to fully utilize the power of your battery packs, it would be a good idea for you to spend some time acquiring a basic understanding of the power management concept from your operating system.

In Windows® operating systems, you can go through Power Options of the Control Panel according to the version of the Windows® operating system the notebook uses. Power options in Windows Vista® include three preferred power plans to choose from:

Balanced

Power Saver

High Performance

Customizing Your Notebook’s Power Settings:

1.Click Start (Windows Vista® logo) > Control Panel.

2.Click Classic View from the task panel.

3.Double-click the Power Options icon.

4.Select a power plan from the options show. To customize specific settings, click Change plan settings beneath the selected power plan.

CHAPTER 2: GETTING TO KNOW YOUR NOTEBOOK

Reducing Power Consumption

Although your notebook (together with the operating system) is capable of power conservation, there are measures you can take to reduce the power consumption:

Use the AC power whenever possible.

Lower the intensity of the LCD backlight. A very bright screen translates to higher power usage.

Use <Fn><F7> to switch from discrete graphics mode to integrated graphics mode. You may have to reboot your computer to switch modes. For more details see “Hybrid Graphics and Integrated Graphics Behaviors” on page 30.

Switch to the Stealth mode to switch from discrete to integrated/binary graphics mode and to activate additional system power savings to extend battery life and to reduce power consumption. Switching into and out of Stealth mode may require a reboot depending on your system configuration and the operating system.

NOTE: The battery pack should be locked in the battery compartment all the time.
