You can select suspend mode by this item. Power
On Suspend is the traditional Green PC suspend
mode, the CPU clock is stop, all other devices are
shut off. But power must be kept On to detect
activities from modem, keyboard/mouse and returns
the system to full power. The system activities is
detected by monitoring the IRQ signals. Suspend to
Hard Drive saves system status, memory and screen
image into hard disk, then the power can be totally
Off. Next time, when power is turned On, the system
goes back to your original work within just few
seconds. You need AOZVHDD to reserve disk space.
Refer to section 3.16 "Suspend to Hard Drive" for
more information".
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.
