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
disc, 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.
