system activity. System activity refers to any activity involving one or
more of the following devices: keyboard, mouse, hard disk, peripherals
connected to the USB ports, and video memory. If no activity is
detected for a period of time (called an inactivity timeout), the
computer stops some or all of these devices in order to conserve

Advanced Configuration and Power Interface (ACPI), which allows for
maximum power conservation and maximum performance at the same
time. Windows handles all power-saving chores for your computer.
