Power Management Features
To conserve power, especially when using the battery, your notebook comput-
er uses the ACPI power management system. Power management conserves
power by controlling individual components of the computer (the monitor and
hard disk drive) or the whole system.
Advanced Configuration and Power Interface (ACPI)
The ACPI interface provides the computer with enhanced power saving tech-
niques and gives the operating system (OS) direct control over the power and
thermal states of devices and processors. For example, it enables the OS to set
devices into low-power states based on user settings and information from ap-
plications. ACPI is available in Windows 2000 and Windows XP.
