Getting Started

Turning off the computer

Sleep mode

The Sleep command places the computer into a power-saving mode. Sleep saves the current state of the computer to memory so that, when you restart the computer, you can continue working from where you left off.

NOTE

After your computer sleeps for an extended period of time, the

 

Windows® operating system may save any open documents and

 

programs to your hard disk, and then shuts down the computer.

 

 

Factors to consider when choosing Sleep:❖While in Sleep mode, the computer uses some main battery power.

❖Because the state of the system is stored in memory, you will lose data if the main battery discharges while the computer is in Sleep mode.

❖Restarting from Sleep takes less time and consumes less main battery power than restarting after turning off the computer using the Hibernation or Shut down commands.

❖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 the battery charge becomes critically low, the computer will try to enter Hibernation mode.

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.
