Toshiba A9 用户指南

154

Dynamically Switchable—This mode is the default setting for 
your computer, and automatically changes the processing 
frequency and decreases voltage depending on the power 
source:

❖

AC Power—If your computer is connected to the AC 
adaptor, the CPU frequency mode is set to high for faster 
processing.

❖

Battery Power—If your computer is running on battery 
power, the CPU frequency mode is set to low for slower 
processing. Switching the CPU to low allows you to 
conserve power and extend the operating time of your 
battery.

Always High—Sets the CPU speed to high when using either 
the battery or the AC adaptor. 

Always Low—Sets the CPU speed to low when using either 
the battery or the AC adaptor.

❖

Boot Priority—Allows you to change the sequence in which 
your computer searches the drives for the operating system

You can also manually choose the Boot Priority by pressing the 
power button, then quickly pressing the F12 key, or the right or 
left arrow keys.

Select the boot device icon by pressing the right or left arrow 
keys, then pressing the Enter key.

Since the system is a quick-booting system, you must press the 
arrow keys immediately after pressing the power button.

❖

Keyboard—Allows you to configure an external PS/2 
keyboard to emulate the 

Fn

 function key and access the wake-

on keyboard function 

❖

USB—Allows you to enable or disable USB Legacy 
Emulation

❖

LAN—Allows you to set networking functions

By changing any of the options that appear in the dialog boxes and 
clicking Apply, you can reconfigure that function. Any options that 
you change will become default settings when you restart your 
system.
