Power Management Features
To conserve power, especially when using the battery, your notebook comput-
er uses
ACPI (Advanced Configuration & Power Interface)
power man-
agement. Power management conserves power by controlling individual
components of the computer (the monitor and hard disk drive) or the whole
system.
Advanced Configuration & Power Interface
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
send devices into low-power states based on user settings and information
from applications.
ACPI
is available in
Windows 2000
and
Windows XP
(see
sidebar note).
OS Note
Power management
functions will vary
slightly depending on
your operating system.
For more information it
is best to refer to the
user’s manual of your
operating system.
