Using Your VAIO Computer
Using the Keyboard
Your keyboard is very similar to a desktop computer keyboard, but has additional keys that perform model-specific tasks.
Combinations and Functions with the Fn Key
Some keyboard functions can be used only after the operating system finished launching.

Fn + 
 (F10): zoom
Changes the screen resolution to magnify/restore your computer's screen view.
The magnified view is not as clear as the standard view, as it is implemented by applying a lower resolution 
to the computer screen with a higher resolution.
This key combination may not work with graphic images as it magnifies the screen view by changing the 
resolution.
The location and size of software windows may change when the screen view is magnified or the standard 
view is restored because pressing this key combination changes the resolution.
When your computer's screen view is magnified, switching the view to the external display disables the 
function and restores the standard view.
Fn + 
 (F12): Hibernate
Provides for the lowest level of power consumption. When you execute this command, the 
states of the system and the connected peripheral devices are written to the hard disk drive and 
the system power is turned off. To return the system to its original state, use the power button 
to turn on the power.
