indefinitely. Restoring information from the hard drive takes
longer than restoring it from memory. When you start up
again, the computer runs a self-test, loads the operating
system, and then returns to the state in which you left it.
Factors to consider when choosing Hibernation mode:
❖ While in Hibernation mode, the computer uses no battery
power.
❖ Because the state of the system is held on the hard disk,
no data is lost if the battery discharges.
❖ Restarting from Hibernation mode uses less time and
battery power than restarting from Turn Off.
❖ 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.
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 to consider when choosing Stand By:
❖ While in Stand By mode, the computer uses some battery
power. A fully charged battery will last up to eight hours
in Stand By mode.
NOTE: If you power down using the Stand By command and the
battery discharges fully, your information will be lost. Be sure to
save your work often.
