Power management

This computer has a built-in power management unit that monitors
system activity. System activity refers to any activity involving one or
more of the following devices: keyboard, mouse, hard disk, peripherals
connected to the serial and parallel 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
energy.
This computer employs a power management scheme that supports
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.
