A hot key is a combination of the 

fn

 key and either the 

esc

 key or one of the function keys .

To use a hot key:

Briefly press the 

fn

 key, and then briefly press the second key of the hot key combination.

 

fn+esc

Displays system information.

fn+f1

Initiates Sleep, which saves your information in system memory. The display and other system
components turn off and power is conserved.

To exit Sleep, briefly press the power button.

To reduce the risk of information loss, save your work before initiating Sleep.

If a critical battery level occurs while the computer is in the Sleep state, the computer

initiates Hibernation and the information stored in memory is saved to the hard drive.

The function of the 

fn+f1

 hot key can be changed. For example, you can set the 

fn+f1

 hot key to

initiate Hibernation instead of Sleep.

fn+f2

Decreases the screen brightness level.

fn+f3

Increases the screen brightness level.

fn+f4

Switches the screen image among display devices connected to the system. For example, if a
monitor is connected to the computer, 

fn+f4

 alternates the screen image from computer display to

monitor display to simultaneous display on both the computer and the monitor.

Most external monitors receive video information from the computer using the external VGA video
standard. The 

fn+f4

 hot key can also alternate images among other devices that are receiving video

information from the computer.

fn+f5

Initiates the QuickLock security feature. QuickLock protects your information by displaying the
operating system Log On window. While the Log On window is displayed, the computer cannot be
accessed until a Windows user password or a Windows administrator password is entered.

Before you can use QuickLock, you must set a Windows user password or a Windows

administrator password. For instructions, refer to Help and Support.
