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 ACPI
(Advanced Configuration and Power Interface) which allows for maximum power
conservation and maximum performance at the same time. Windows handles all
power-saving chores for your computer.
Advanced Configuration and Power Interface
Advanced Configuration and Power Interface (ACPI) is a power management
specification jointly developed by Compaq, Intel, Microsoft, Phoenix and Toshiba.
ACPI enables Windows to control the amount of power given to each device
attached to the computer. With ACPI, Windows can turn off peripheral devices
when they are not in use, thereby saving power.
Refer to Windows help for more details.
