Identifying the hot keys

▲ Briefly press the fn key, and then briefly press the second key of the hot key combination.
hot key combination Description
fn + f3 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.
CAUTION: To reduce the risk of information loss, save your work before initiating Sleep.
NOTE: If a critical battery level occurs while the computer is in the Sleep state, the computer
initiates Hibernation and the information stored in system memory is saved to the hard drive.
The function of the fn + f3 hot key can be changed. For example, you can set the fn + f3 to initiate
Hibernation instead of Sleep. In all Windows operating system windows, references to the sleep
button apply to the
fn + f3 hot key.
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 + f6 Decreases speaker volume.
fn + f7 Increases speaker volume.
fn + f8 Mutes or restores microphone sound.
fn + f9 Decreases the screen brightness level.
fn + f10 Increases the screen brightness level.
