Powering down the computer
When you power down the computer, you have a number of
options to choose from:
❖Turn Off or Shut down, which power off the computer
❖Hibernation, which saves the current operating state to
the hard disk and powers off the computer
❖Stand by, which saves the current operating state to
memory and enters a low power mode
❖Restart, which restarts the computer
Each option has its advantages.
TECHNICAL NOTE: Before using any of these options to power
down your computer, save your files and make sure the disk
activity lights are off.
If you change your mind and decide to continue working after all,
wait a few seconds before turning the computer on again.

Turn Off or Shut down command

The Turn Off or Shut down commands power off the
computer. The Windows® XP Home operating system uses
the Turn Off command. The Windows® XP Pro operating
system uses the Turn Off command if you are not connected
to a Windows® domain server. The Windows® XP Pro
operating system uses the Shut down command if you are a
member of a domain.
Factors to consider when choosing Turn Off or Shut down:
❖No power is used while the computer is turned off. This
is the most efficient mode if you will be away from your
computer for an extended time.
❖Restarting from Turn Off or Shut down uses the most
time and battery power.
