It looks like EIST(speedstep) is not enabled, or it's not supported. Please check BIOS and give us "psrinfo -vp" report.

I have noticed this high battery consumption with more recent builds (say snv_100), but I am not exactly sure which one. I am not sure if cpupm is enabled. I didn't do anything to enable it. Here is an output of powertop running on my machine. Look at your /etc/power.conf file and see if you see a line like: cpupm enable Also, a line like: cpu-threshold 1s would be good. And make sure SpeedStep is enable in your BIOS setup. I assume that it is.
