Th laptop I use (not mine, my bosses) is not a centrino, but does have the "speedstep" capability. I know that there is a setting in the bios do disable that functionality (and I do) although it is reset when I log back into the network at the office, I suppose by a script that the net heads have execute at each logon.

thanks, but I can't change it on mine ! the setting is allready ready set to max speed ?

but when i check /proc/ then I see this :
jherrera@linux:/proc> cat cpufreq
minimum CPU frequency - maximum CPU frequency - policy
CPU 0 600000 kHz ( 37 %) - 1600000 kHz (100 %) - userspace
jherrera@linux:/proc>

what's means this ?

As root you can echo a value to the proc. For an example, type

echo "0:1600000:1600000:powersave" >/proc/cpufreq


I got the information from http://www.linuxquestions.org/questi...hreadid=200149
