Signal Pin # Description I/O PU/PD Comment
SUS_S4# A18 Indicates system is in Suspend to Disk state. Active low output. O 3.3 VSB Not supported
SUS_S5# A24 Indicates system is in Soft Off state. O 3.3 VSB
WAKE0# B66 PCI Express wake up signal. I 3.3 VSB PU 1 kΩ 3.3 VSB
WAKE1# B67 General purpose wake up signal. May be used to implement wake-up on PS/2 keyboard or
mouse activity.
I 3.3 VSB PU 10 kΩ 3.3 VSB
BATLOW# A27 Battery low input. This signal may be driven low by external circuitry to signal that the system
battery is low, or may be used to signal some other external power-management event.
I 3.3 VSB PU 10 kΩ 3.3 VSB
LID# A103 Lid button. Used by the ACPI operating system for a LID switch.
Note: For proper detection, assert a pulse width of at least 16 ms.
I OD 3.3 V PU 10 kΩ 3.3 VSB
SLEEP# B103 Sleep button. Used by the ACPI operating system to bring the system to sleep state or to wake it
up again.
Note: For proper detection, assert a pulse width of at least 16 ms.
I OD 3.3 V PU 100 kΩ 3.3 VSB
