Managing System Power (Windows Vista® Operating System)
In the Windows Vista® operating system environment, your notebook manages its power resources using the Advanced Configuration and Power Interface (ACPI) while the notebook is powered on using AC or battery (DC) power. ACPI enables the operating system to manage the power given to each attached device and to turn off a device when not in use.
Take advantage of the opportunity to manage power on your notebook to:
•Minimise battery drain.
•Preserve the life of your notebook.
•Save time. When you return from that urgent call or meeting, you don’t have to reboot, just press the Power button to resume notebook operation.
