Learning the Basics Powering down the computer 23 ❖ When starting up again, the system does not automatically open the programs and files you were previously using. Restart is the same as Turn Off but automatically powers up the computer. Hibernation command The Hibernation command powers off the computer, but it first saves the current state of the computer to the hard disk. Since Hibernation 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 to consider when choosing Hibernation: ❖ 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 while the computer is in Hibernation mode. ❖ When starting up again, this choice uses less time and battery power than the Turn Off option. But it uses a little more time and battery power to start up than the Standby option, because information is being retrieved from the hard disk instead of from memory. ❖ On restarting, the computer returns to the state in which you left it, and opens all the programs and files you were using. Standby command The Standby command puts the computer into a powersaving mode. Standby stores the current state of the computer in memory so that, when you restart the computer, you can continue working from where you left off.

Learning the Basics
Powering down the computer
❖
When starting up again, the system does not
automatically open the programs and files you were
previously using.
Restart is the same as Turn Off but automatically powers up
the computer.
Hibernation command
The Hibernation command powers off the computer, but it
first saves the current state of the computer to the hard disk.
Since Hibernation 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 to consider when choosing Hibernation:
❖
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 while the
computer is in Hibernation mode.
❖
When starting up again, this choice uses less time and
battery power than the Turn Off option. But it uses a little
more time and battery power to start up than the Standby
option, because information is being retrieved from the
hard disk instead of from memory.
❖
On restarting, the computer returns to the state in which
you left it, and opens all the programs and files you were
using.
Standby command
The Standby command puts the computer into a power-
saving mode. Standby stores the current state of the computer
in memory so that, when you restart the computer, you can
continue working from where you left off.
