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, Windows ME 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 entered.
= You can also invoke power management options manually at any time by pressing the
appropriate key. See “To use manual power management” below.
To use automated power management
System hibernation, standby, monitor, and hard disk timeouts automatically occur based
on the values set in the Power Management Properties window (Windows 98) or the
Power Options Properties window (Windows ME and Windows 2000). The following
tables describe the power management timeouts you can set in Windows.
System hibernation
Action

down. Provides maximum power savings
while still allowing you to recover the
