This port provides a battery-low signal to the Module for orderly
transitioning to power saving or power cut-off ACPI modes.
LID# A103 I OD CMOS 3.3V Suspend/12V PU 10K to 3.3VSB LID switch. Low active signal used by the ACPI operating system for a LID switch.
(Recommend add Protecting Logic Level Signals on Pins Reclaimed from VCC_12V)
SLEEP# B103 I OD CMOS 3.3V Suspend/12V PU 10K to 3.3VSB
Sleep button. Low active signal used by the ACPI operating system to bring the
system to sleep state or to wake it up again.
(Recommend add Protecting Logic Level Signals on Pins Reclaimed from VCC_12V)
THRM# B35 I CMOS 3.3V / 3.3V PU 10K to 3.3V Input from off-Module temp sensor indicating an over-temp situation.
THRMTRIP# A35 O CMOS 3.3V / 3.3V PU 10K to 3.3V Active low output indicating that the CPU has entered thermal shutdown.
SMB_CK B13 I/O OD CMOS 3.3V Suspend/3.3V PU 2.2K to 3.3VSB System Management Bus bidirectional clock line.
SMB_DAT B14 I/O OD CMOS 3.3V Suspend/3.3V PU 2.2K to 3.3VSB System Management Bus bidirectional data line.
SMB_ALERT# B15 I CMOS 3.3V Suspend/3.3V PU 10K to 3.3VSB
System Management Bus Alert – active low input can be used to
generate an SMI# (System Management Interrupt) or to wake the system.
