HDD Power Down
Also known as Hard Disk Timeout or IDE Standby Power
Down Mode, this setting allows automatic power down of IDE
drives after a specified period of inactivity 10 minutes is a
suggested minimum, to avoid undue wear and tear on the
drive. The choices are:
Disabled / 1 minutes / 5 minutes / 10 minutes /
30 minutes / 45 minutes / 60 minutes
CPU THRM-Throttling
This BIOS feature determines the clock speed of the proces-
sor when it is in the Suspend To RAM (STR) power saving
mode. It has no effect when the processor is in normal active
mode.
Available options for this BIOS feature are preset values of
the processor's power consumption. They range from 12.5%
to 87.5%. Please note that these options reflect the desired
power consumption of the processor, not its clock speed. The
clock speed of the processor will be determined based on the
option chosen.
The default setting is usually 62.5%. This means the proces-
sor will be running at a clock speed that allows it to use
37.5% less power.
The choice of what you should set the processor to run at is
really up to you. The lower the value, the more power you will
save when the processor is in Suspend To RAM mode. Gen-
erally, it would be nice to minimize power consumption while
in Suspend To RAM mode. The only potential drawback
might be a slightly longer time required to bring the processor
back to speed.
It is common for this BIOS feature to be mistaken as a BIOS
control for the Pentium 4's Thermal Monitor feature. How-
ever, the clock throttling provided by this BIOS feature is
completely different from the Pentium 4's Thermal Monitor
feature. The possible values are:
87.5% / 75.0% / 62.5%/ 50.0%/ 25.3%/ 12.5%
