Functionality Description

Pin Name(s)1

SUSWARN# or

SUSPWRDNACK

(Mobile Only)

Used by Intel® ME as either SUSWARN# in Deep S4/S5

state supported platforms or as SUSPWRDNACK in non

Deep S4/S5 state supported platforms.

SUSWARN#

/SUSPWRDNACK#/

GPIO30

AC Present

(Mobile Only)

Input signal from the Embedded Controller (EC) on

Mobile systems to indicate AC power source or the

system battery. Active High indicates AC power.

ACPRESENT /

GPIO31

Temperature

Alert

Used as an alert (active low) to indicate to the external

controller (such as EC or SIO) that temperatures are out

of range for the PCH or Graphics/Memory Controller or

the processor core.

SATA5GP / GPIO49

/ TEMP_ALERT#

Processor

Missing

(Desktop Only)

Used to indicate Processor Missing to the Intel

Management Engine.

SMBALERT#

signal from PSU

to PCH

Indicates the PSU may cause system shutdown due to a

momentary loss of AC input voltage or an over

temperature condition.

MGPIO2

Intel ME FW

Recovery Mode

Strap

Input to PCH to force Intel ME to stay in recovery boot

loader.
