Powering down the computer
Powering down the computer
When you power down the computer, you have three options to
choose from: Turn Off Computer, Hibernation and Standby. Each
option has its advantages.
Turn off computer command
The Turn off computer 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 to consider when choosing Turn off computer:
❖ 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 Shut down 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
Hibernation shuts the computer down completely, 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 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:
❖ While in Hibernation, the computer uses no battery power.
