XP power management features can reduce the amount of electricity
your computer uses when it is on and you are not using it. You can reduce power to just the monitor
or the hard drive, or you can use standby mode or hibernate mode to reduce power to the entire
computer. When the computer exits from a power conservation mode, the Windows desktop is
restored to the state it was in before it entered the mode.
NOTE: Windows XP Professional includes security and networking features not available in
Windows XP Home Edition. When a Windows XP Professional computer is connected to a network,
different options related to security and networking appear in certain windows.
