Introduction

Two levels of password security, supervisor and 
user, are available to prevent unauthorized 
access to your computer.

A hot key function blanks the screen and 
disables the computer providing data security.

A microprocessor in the computer’s intelligent 
power supply detects the battery’s charge and 
calculates the remaining battery capacity. It also 
protects electronic components from abnormal 
conditions, such as voltage overload from an AC 
adaptor. This can be specified in the Power 
Options. 

This feature allows you to configure the computer 
in order to save battery power. This can be 
specified in the Power Options.

This feature turns power to the computer off 
when the display panel is closed and turns it 
back on when the panel is opened. This can be 
specified in the Power Options. 

When battery power is exhausted to the point 
that computer operation cannot be continued, the 
system automatically enters hibernation and 
shuts down. This can be specified in the Power 
Options. 

To protect from overheating, the CPU has an 
internal temperature sensor. If the computer’s 
internal temperature rises to a certain level, the 
cooling fan is turned on or the processing speed 
is lowered. This can be specified in the Power 
Options.
