C-state not showing in powertop

rengo.Java · 09-19-2007, 07:00 AM

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.

Also what linux distribution/version and kernel are you running?

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