Press 

fn+f4

 to switch the screen image among display devices connected to the system. For example,

if a monitor is connected to the computer, each time you press 

fn+f4

 the image switches among the

computer display, the monitor display, and a 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

 hotkey can also toggle images among other devices receiving video information

from the computer, such as S-Video.

The following video transmission types, with examples of devices that use them, are supported by
the 

fn+f4

 hotkey:

●

LCD (computer display)

●

External VGA (most external monitors)

●

S-Video (televisions, camcorders, VCRs, and video capture cards with S-Video-in jacks, on select
models)

Press 

fn+f5

 to initiate Hibernation.

When Hibernation is initiated, your information is saved to a hibernation file on the hard drive and the
computer turns off.

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

The computer must be on before you initiate Hibernation.

To exit Hibernation, briefly press the power button.

The function of the 

fn+f5

 hotkey can be changed. For example, you can set the 

fn+f5

 hotkey to initiate

Sleep instead of Hibernation.
