LID# A103 I OD CMOS 3.3V Suspend/12V PU 47K to 3.3VSB LID switch. Low active signal used by the ACPI operating system for a LID switch.
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.
THRM# B35 I CMOS 3.3V / 3.3V PU 10K to 3.3VSB Input from off-Module temp sensor indicating an over-temp situation.
THRMTRIP# A35 O CMOS 3.3V / 3.3V PU 10K to 3.3VSB 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.
