So - that's kondemand.

Well yes i guess that would answer my thread question,but still question is why i takes up to 20 percent of cpu.

For the uninitiated, kondemand is a kernel thread that belongs to the ondemand governor of cpufreq subsystem, which changes the p-states of the system, based on the utilization statistics. Thus it’s something that helps in power management.
Did you have a specific question other than "what is it"?

I had a problem with that damn process chewing up 70% of my CPU on my laptop. The solution was to take out the battery, unplug the laptop, and wait about 10 seconds. Prior to this I had shutdown and re-boot numerous times. For some reason only after disconnecting the battery AND SHUTTING THE LAPTOP OFF, solved the problem. That process (kondemand) still runs, but now only at .1% of CPU.
