PWRBTN#
I
CMOS 3.3V Sus
ePU = 10 KΩ
Power button to bring system out of or into Suspend states.
Board Controller
SYS_RESET#
I
CMOS 3.3V Sus 3.3V
ePU = 10 KΩ
Reset button input.
Board Controller
CB_RESET#
O
CMOS 3.3V Sus 3.3V,
24mA
ePU = 10 KΩ
eSR = 22.6 Ω
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.
PCH
PWR_OK
I
CMOS 3.3V Sus 12V
iPU = 90
KΩ
Power OK from main power supply. A high value indicates that the
power is good.

SUS_STAT#
O
CMOS 3.3V Sus 3.3V,
0.5mA (I
oh
)
ePU = 10 KΩ
Indicates imminent suspend operation; used to notify LPC devices.
PCH
SUS_S3#
O
CMOS 3.3V Sus 3.3V,
24mA
Indicates system is in Suspend to RAM state. Active low output.
PCH
SUS_S4#
O
CMOS 3.3V Sus 3.3V,
24mA
Indicates system is in Suspend to Disk state. Active low output.
PCH
SUS_S5#
O
CMOS 3.3V Sus 3.3V,
0.5mA (I
oh
)
Indicates system is in Soft Off state. Also known as "PS_ON" and
can be used to control an ATX power supply.
PCH
WAKE0#
I
CMOS 3.3V Sus 3.3V
ePU = 10 KΩ
PCI Express wake-up signal.
PCH
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.
PCH
BATLOW#
I
CMOS 3.3V Sus 3.3V
ePU = 10 KΩ Indicates that external battery is low.
NOTE: When pulled low, this line will prevent the system from
starting!
PCH, Board
Controller
LID#
I
CMOS 3.3V Sus 12V
ePU = 10 KΩ
LID switch. Low active signal used by ACPI operating system for LID
switch.
PCH, Board
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.
