Part 1 : KPowersave walkthrough  |  Part 2 : CPU Frequency Policy


The CPU Frequency Policy sets the relative speed of the processor. Currently KPowersave in Mepis 6.0 and 6.5 supports 3 modes: Performance  |  Dynamic  |  Powersave.


Performance: This mode drives the processor at the rated operating speed.

Dynamic: This mode changes the processor speed depending on use of the processor. The more programs that are open and running, the higher the clock speed. The intent is that the processing strength is there when it is needed, but if you don't need the processing strength, you can still conserve on power.

Powersave: This mode clocks the processor all the way down.

Not All Laptops clock the same. Some laptops will not downclock at all.


22: Below is a screenshot of KInfoCenter with the computer running on it's battery.

Here we can see that the computer speed has been set at 375mhz.





23: Plugging the power cord in, and our speed is now set at 3000mhz.





24: For this demonstration I've opened up glxgears





25: Once again, our starting speed is 3000mhz





26: Unplug the Power Cord





27: Our Speed drops to 375mhz as expected.





28: Right Click on KPowersave to bring up the Context Menu





29: Mouse up to Set CPU Frequency Policy





30: Left Click on Dynamic





31: With the Power Cord unplugged, the clock speed is set at 3000mhz.





32: Close glxgears





33: Now Our Speed is set at 750mhz.
