C-state not showing in powertop


Hi all!!

In my try to enlarge my battery duration on my laptop, im using the powertop utility (http://www.linuxpowertop.org).
But it says to me:
"Detailed C-state information is only available on Mobile CPUs (laptops)"

I have my kernel configured whith CPU_FREQ support, al the cpu governor, ACPI support.

I dont know how to make it works.
(Another thing that dont works is the xfce4-cpufreq plugin, i think because the same cause)
Whith a previous kernel compilation all it works, but in the new one not.

Any ideas?

Thanks!

PS: Sorry my bad english

Post the make/model of your laptop.
Does it have an Intel mobile processor? If not then the laptop is not compatable with this tool.

Which kernel version are you running it with? Which kernel version did it work with? Are you running it as root?
