Hi all. It seams that my laptop doesn't have a CPU power management driver.
More info:

kernel 2.6.27-7-generic

Code:
simi@laptop:~$ cpufreq-info          
cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to linux@brodo.de, please.             
analyzing CPU 0:                                              
  no or unknown cpufreq driver is active on this CPU
About my laptop model is an ASUS X51 and the windows driver cd has an application for CPU management, i need some help to find out if i can find some driver and set it up (my old laptop worked out of the box and when it was idle it automaticaly lowed the CPU freqvency from 1200 to 800 that maked the fan stop or run slower)
