Turning Off the Computer
For best results when using Windows Vista, do not shut down the computer except when you
must turn off the power for safety reasons: to make repairs, to install new hardware or cards
in the computer, or to change a battery.
As an alternative to shutting down the computer, you can lock it or put it into either Sleep or
Hibernate mode, if it is available. You can set the power management timers to put the
computer automatically into Sleep or Hibernate mode.
The computer has these reduced power states:
Sleep mode saves your work to memory, so you can resume quickly. It saves memory to
the hard disk drive, and then goes into a reduced-power state. During Sleep mode, the
computer hardware light remains on, and the computer is ready to wake quickly and
resume your work where you left off.
Hibernate mode (available as an advanced power setting) saves the system memory
to a temporary file on the hard disk and then turns off the hardware. When you turn on
the computer again, the programs, folders, and documents that you had open are
restored to the screen.
