Description
Power button to bring system out of or into Suspend states.
Reset button input.
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.
Power OK from main power supply. A high value indicates that the
power is good.
Indicates imminent suspend operation; used to notify LPC devices.
Indicates system is in Suspend to RAM state. Active low output.
Indicates system is in Suspend to Disk state. Active low output.
Shorted to SUS_S5#.
Indicates system is in Soft Off state. Also known as "PS_ON" and
can be used to control an ATX power supply.
PCI Express wake-up signal.
General purpose wake up signal. May be used to implement wake-
up on PS2 keyboard or mouse activity.
Indicates that external battery is low.
NOTE: When LOW (not pulled up), this line will prevent the system
from starting!
LID switch. Low active signal used by ACPI operating system for LID
switch.
Sleep button. Low active signal used by ACPI operating system to
bring the system to sleep state or wake it up again.
