Power management
Your computer features a built-in power management unit that con-
stantly monitors system activity. System activity refers to any activity 
involving one or more of the following devices: keyboard, touchpad/
mouse, floppy disk drive, hard disk drive, optical drive, peripherals con-
nected 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 
ACPI (Advanced Configuration and Power Interface), enabling maxi-
mum 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 for 
more information.
