Power management
Your computer features a built-in power management unit that
constantly monitors system activity. System activity refers to any
activity involving one or more of the following devices: keyboard,
touchpad/mouse, hard disk drive, optical drive, peripherals connected
to the computer, and video memory. If no activity is detected for a
period of time (the settings are controlled in Windows Power
Management), the computer turns off some, or all, of these devices in
order to conserve power.
Your computer employs a power management scheme that supports
Advanced Configuration and Power Interface (ACPI), enabling
maximum power conservation without compromising system
performance. ACPI allows Windows to control the amount of power
given to each device attached to the computer. In this way, Windows
handles all power-saving chores for your computer. Refer to Windows
Help and Support for more information.
