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. ACPI enables Windows to control the amount of power given to
each device attached to the computer. Windows handles all power-
saving chores for your computer. For more information, refer to
Windows help.
