Clock Throttling means at the Doze/Standby state,
the CPU clock count in a given time (not the
frequency) is reduced to the ratio specified in this
parameter. Actually, the period per CPU clock is not
changed. For example, a 66MHz CPU clock remains
the same 30ns clock period when system goes into
Doze/Suspend. The chipset generates the STPCLK
(stop clock) signal periodically to prevent CPU for
accepting clock from clock generator. For full power
on, the CPU can receive 66M count in one second. If
the Slow Clock Ratio is set to 50%, the CPU will only
receive 33M clock count in one second. This will
effectively reduce CPU speed as well as CPU power.
To enable or disable the detection of VGA activity for
power down state transition.
This is a specification of ACPI and supported by
hardware. When Enabled , the soft power switch on
the front panel can be used to control power On,
Suspend and Off. If the switch is pressed less than 4
sec during power On, the system will go into Suspend
mode. If the switch is pressed longer than 4 sec, the
system will be turned Off. The default setting is
Disabled , soft power switch is only used to control On
and Off, there is no need to press 4 sec, and there is
no Suspend.
