Table 11 Miscellaneous Signals
Signal Name Pin # Type Description Notes
FACE_PRSNT# PX1-B34 I
FACE module presence
detection. Must be connected
to GND.
PWR_BTN# PX1-A43 I
Power button - causes an SMI
or SCI to indicate a system
request to enter a sleep state. If
the system is already in a sleep
state, this signal will cause a
wake event. If PWR_BTN# is
asserted for more than 4
seconds, it will cause an
unconditional transition (power
button override) to the S5 state
with only the PWR_BTN#
available as a wake event.
Override will occur even if the
system is in the S1 state. This
signal has an internal pull-up
resistor.
SLEEP_S3# PX1-B43
O
S3 sleep power plane control.
Assertion of SLP_S3# shuts
off power to non-critical
components when system
transitions to S3, S4, or S5
states. De-assertion of
SLP_S3# turns on power to
non-critical components when
system transitions from S3, S4,
or S5 back to S0.
