Managing Power Consumption
When you are not using your computer, you will want to maximize battery operating time
without compromising performance. It is not necessary to turn the computer off in order to
reduce power consumption and extend battery life.
With Windows 98 and Windows 2000, Advanced Configuration and Power Interface
(ACPI) provides both manual and automated tools for reducing power consumption.
• You can set power management options to occur automatically, based on timeout
values that you have entered. See “To use automated power management” below.
• You can also invoke power management options manually at any time by pressing the
appropriate key. See “To use manual power management” below.
