Dear Sir/Madam,

I am trying to install powerTop on my PC as I need to know the per
process power consumption.
I have the Ubuntu 11.10 installed on my PC.
I installed the package available in Ubuntu Synaptic Package Manger
but the power consumption in watts is not displayed.
I get the message "no ACPI power usage estimate available".
Is there any configuration settings that I am missing ?

Could you please tell me on which version of the kernel is powerTop supported ?

Also in the readme file it says "The patches in the patches/
sub-directory are required for PowerTOP to function fully." but I was
not able to find this directory in the tar.bz2.
Could you please also tell me where I will find the patches directory ?

Thanking you,
Srikanth
