PWRBTN# (Power Button)
Processor Initiated Passive Cooling
(Via Programmed Duty Cycle on STPCLK#)
Using the THTL_EN and THTL_DTY bits, the ICH5 can force a programmed duty cycle on the
STPCLK# signal. This reduces the effective instruction rate of the processor and cuts its power
consumption and heat generation.
Active Cooling
Active cooling involves fans. The GPIO signals from the ICH5 can be used to turn on/off a fan.
Event Input Signals and Their Usage
The ICH5 has various input signals that trigger specific events. This section describes those signals
and how they should be used.
The ICH5 PWRBTN# signal operates as a “Fixed Power Button” as described in the Advanced
Configuration and Power Interface, Version 2.0b. PWRBTN# signal has a 16 ms de-bounce on the
input. The state transition descriptions are included in
soon as the PWRBTN# is pressed (but after the debounce logic), and does not depend on when the
Power Button is released.
the Power Button is not a wake event. Refer to Power Button Override Function section below for
further detail.
