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.

Windows 98/ Me. Battery low and battery very low warnings are configured

using the Power Management option.

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
