Power and Signal Distribution

7.3Power Control

System power is controlled through the power button and external events.

7.3.1 Power Button

Pressing and releasing the power button applies a negative (grounding) pulse to the power control logic on the system board. The resultant action of pressing the power button depends on the state and mode of the system at that time and is described as follows:

 

Table 7-4.

 

Power Button Actions

 

 

System State

Pressed Power Button Results In:

Off

Negative pulse, of which the falling edge results in power control logic

 

asserting PS On signal to Power Supply Assembly, which then initializes. ACPI

 

four-second counter is not active.

 

 

On, ACPI Disabled

Negative pulse, of which the falling edge causes power control logic to

 

de-assert the PS On signal. ACPI four-second counter is not active.

 

 

On, ACPI Enabled

Pressed and Released Under Four Seconds:

 

Negative pulse, of which the falling edge causes power control logic to

 

generate SMI-, set a bit in the SMI source register, set a bit for button status,

 

and start four-second counter. Software should clear the button status bit within

 

four seconds and the Suspend state is entered. If the status bit is not cleared by

 

software in four seconds PS On is de-asserted and the power supply assembly

 

shuts down (this operation is meant as a guard if the OS is hung).

 

Pressed and Held At least Four Seconds Before Release:

 

If the button is held in for at least four seconds and then released, PS On is

 

negated, de-activating the power supply.
