Using Power Management Options

Your computer includes power-management options that can help the battery charge last longer and extend the life of the battery, LCD panel, and other components. Power-management options slow down or shut off system components when the components are not being used.

Power management may slow down system performance. Your computer runs fastest with the power cord attached, when power management is disabled.

Windows 98/ Me has two Power Management strategies:

•APM (Advanced Power Management) mode: Under APM mode, Windows 98/ Me Power management works with the settings in the Power Management option on the Control Panel except for rest mode.

•ACPI (Advanced Configuration and Power Management Interface) mode: Under the ACPI mode, All the settings in System Setup have no effect on Windows 98/ Me. Battery low and battery very low warnings are configured using the Power Management option.

If you want to use Hibernation function in ACPI mode (Windows 98/ Me), then click Start > Settings > Control Panel and double click Power Management icon. Select Hibernate on the When I press the sleep button on my computer field in Advanced tap. Then you can use the power button for activating the hibernation function.

If you want to shut down your computer by pressing the power button, see “ACPI(Advanced Configuration and Power Interface) mode” on page 8.

If your computer uses DOS or Windows 95, Power Management works with the settings in System Setup

If your computer shipped from the factory with Windows NT installed,
