1

Power button

 

The power button turns system power off and on.

 

 

 

NOTICE: If you turn off the system using the power button and the

 

 

 

system is running an ACPI-compliant operating system, the system

 

 

 

can perform an orderly shutdown before power is turned off. If the

 

 

 

power button is pressed for more than 4 seconds, the system power

 

 

 

will turn off regardless of the current operating system state. If the

 

 

 

system is not running an ACPI-compliant operating system, power is

 

 

 

turned off immediately after the power button is pressed.

 

 

 

The power button is enabled in the System Setup program. When

 

 

 

disabled, the button can only turn the system power on. For more

 

 

 

information, see "Using the System Setup Program" on page 29 and the

 

 

 

operating system's documentation.
