Chapter 3: Power Management
Overview
To conserve power, especially when using the battery, your computer power man-
agement conserves power by controlling individual components of the computer
(the monitor and hard disk drive) or the whole system. This chapter covers:
• The Power Sources
• Turning On the Computer
• Shutting the Computer Down
• Power-Saving States
• Configuring the Power Buttons
• Battery Information
The computer uses enhanced power saving techniques to give the operating system
(OS) direct control over the power and thermal states of devices and processors. For
example, this enables the OS to set devices into low-power states based on user set-
tings and information from applications.
