Getting Started
Turning off the computer
Factors to consider when choosing Sleep:
❖ While in Sleep mode, the computer uses some main battery 
power.
❖ The Sleep command does not store unsaved information on 
your hard disk. You should save your work before putting your 
computer on Sleep.
❖ Restarting from Sleep takes less time and consumes less main 
battery power than restarting from turning off the computer or 
using Hibernation mode.
❖ When starting up again, the computer returns to the mode in 
which you left it, including all open programs and files you 
were using.
If you power down using the Sleep command and the main battery 
discharges fully, your unsaved information will be lost. Be sure to 
save your work first.
For information on using Sleep, see “Using and configuring Sleep 
mode” on page 77.
Using the Shut Down command
The Shut Down command completely shuts down the computer 
without saving your work or the current state of the computer. This 
command closes all open programs, shuts down the operating 
system, and then turns off your computer.
Use the following steps to turn off your computer using the Shut 
Down command:
