Suspend Mode Option
Power On Suspend
Suspend to Hard Drive
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.
