Description
Source / Target
PWRBTN#
I
CMOS 3.3V Sus
ePU = 10 KΩ
Power button to bring system out of or into Suspend states.
Embedded
Controller
SYS_RESET#
I
CMOS 3.3V Sus 3.3V
ePU = 10 KΩ
Reset button input.
Embedded
Controller
CB_RESET#
O
CMOS 3.3V Sus 3.3V, 7mA
Reset output from module to Carrier Board. Active low. Issued by
module chipset and may result from a low SYS_RESET# input, a
low PWR_OK input, a VCC_12V power input that falls below the
minimum specification, a watchdog timeout, or may be initiated by
the module software.
AL SOC
PWR_OK
I
CMOS 3.3V Sus 12V
ePU = 10
KΩ
Power OK from main power supply. A high value indicates that the
power is good.
Embedded
Controller
SUS_STAT#
O
CMOS 3.3V Sus 3.3V, 7mA
Indicates imminent suspend operation; used to notify LPC devices.
AL SOC
SUS_S3#
O
CMOS 3.3V Sus 3.3V, 7mA
Indicates system is in Suspend to RAM state. Active low output.
AL SOC
SUS_S4#
O
CMOS 3.3V Sus 3.3V, 7mA
Indicates system is in Suspend to Disk state. Active low output.
Shorted to SUS_S5#.
AL SOC
SUS_S5#
O
CMOS 3.3V Sus 3.3V, 7mA
Indicates system is in Soft Off state. Also known as "PS_ON" and
can be used to control an ATX power supply.
AL SOC
WAKE0#
I
CMOS 3.3V Sus 3.3V
ePU = 10 KΩ
PCI Express wake-up signal.
AL SOC
WAKE1#
I
CMOS 3.3V Sus 3.3V
ePU = 10 KΩ
General purpose wake up signal. May be used to implement wake-
up on PS2 keyboard or mouse activity.
AL SOC
BATLOW#
I
CMOS 3.3V Sus 3.3V
ePU = 10 KΩ Indicates that external battery is low.
NOTE: When LOW (not pulled up), this line will prevent the system
from starting!
AL SOC,

Controller
LID#
I
CMOS 3.3V Sus 12V
ePU = 10 KΩ
LID switch. Low active signal used by ACPI operating system for LID
switch.
AL SOC,
Embedded
Controller
SLEEP#
I
CMOS 3.3V Sus 12V
ePU = 10 KΩ
Sleep button. Low active signal used by ACPI operating system to
bring the system to sleep state or wake it up again.
