❖Restarting from Hibernation mode uses less time and
battery power than restarting from Shut Down.
❖Restarting from Hibernation mode uses a little more time
and battery power than restarting from Stand By because
information is being retrieved from the hard disk instead
of memory.
❖When starting up again, the computer returns to the state
in which you left it, including all open programs and files
you were using.
For more information about the Hibernation command, see
“Using Hibernation” on page 88. For information about
going into Hibernation mode more quickly, see “Going into
Hibernation mode more quickly” on page 89.
Stand By command
The Stand By command puts the computer into a power-
saving mode. Stand By holds the current state of the
computer in memory so that, when you restart the computer,
you can continue working from where you left off.
Factors when choosing Stand By:
❖While in Stand By mode, the computer uses some battery
power. The battery will eventually discharge in Stand By
mode. If the battery discharges, your data will be lost if
you do not save your work before entering Stand By
mode.
❖Restarting from Stand By mode uses less time and
battery power than restarting from Shut Down or
Hibernation mode.
