Part I: Getting to Know Windows 7
• Sleep: This option reduces the computer’s power
consumption without exiting Windows 7 or closing
programs. As a result, when you wake the computer
by moving the mouse or touching the keyboard,
everything is exactly as you left it: programs and
documents are open, if they were before Sleep.
• Hibernate: This option combines Sleep and Shut
Down. Hibernate records which programs are
running but completely shuts down the computer.
When you start the computer, Windows 7 opens
all programs you were using, just like Sleep.
Hibernate or Shut Down are equally green options —
they save the same amount of power. Sleep is a little
less green, but saves time in returning to a task you’re
in the middle of.
4. Choose Shutdown to turn off the computer.
On most computers, pressing the power switch also
shuts down the computer. On a laptop, closing the
lid may shut down the laptop or put it into Sleep or
Hibernation mode.
For a desktop computer, consider using a power strip
to plug in the computer, the monitor, and the printer.
After you shut down or hibernate the computer, turn
the power strip off. This saves the most power.
