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, floppy drive, 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 the
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.
