To switch a processor into a power saving mode, use the parameter “Slow Clock Ratio” (Manual Throttle Ratio, Throttle Duty Cycle) which allows setting the frequency of clock signal in a power saving suspend mode. This parameter may have the following values (in per cents from the normal processor frequency): 0-12,5%, 12,5-25%, 25-37,5%, … 75-87,5%. This parameter may also be called “Standby CPU Speed”. In this case it has got four preset operating modes of a processor: Max – a standard operating mode when a processor does not switch off while entering the power saving mode; High – a processor operates at one half from a
standard value of a cycle frequency; Medium – it operates at one eighth; Low – at one sixteenth.
To switch off a processor fan, use the parameter “CPUFAN Off in Suspend” which has got two values: Enabled and Disabled.
Another important parameter is “Video Off Option” (Video Off After). Using this parameter, you can define in what modes a monitor should be switched off. This parameter has got the following values: Always On – a monitor is always on even if a system is in the power saving mode; Suspend-Off – switching a monitor off after entering the suspend mode; All modes Off – switching a monitor off after entering any power saving state.
It is also possible to set the operation of a power light indicator in the power saving mode. It is located on the front of your computer. A signal from LED can be indicated by using the parameter “Sleep State LED” which has got two values: Blinking and Dual Color.
