Turn Off command
The Turn Off command shuts the computer down completely.
When you start up again, the computer runs a self-test and
loads the operating system. You must open any programs and
files you want to use.
Factors when choosing Turn Off:
❖
No power is used while the computer is shut down. This
is the most efficient mode if you will be away from your
computer for an extended time.
❖
Restarting from Turn Off uses the most time and battery
power.
❖
When starting up again, the system does not
automatically open programs and files you were
previously using.
Hibernation command
The Hibernation command shuts the computer down
completely, but it first saves the current state of the computer
to the hard disk. Since Hibernation mode does not require
power to maintain the saved information, the system settings
are retained indefinitely. Restoring information from the hard
disk 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 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.
