If I am not mistaken, I made the following modifications to the system after having installed and run powertop without problem:
1) added the following parameters to grub: "pcie_aspm=force i915.i915_enable_rc6=1 i915.lvds_downclock=1 i915.i915_enable_fbc=1"
2) installed the following packages: tlp tlp-rdw tp-smapi-dkms smartmontools ethtool
I removed them and restarted the system, but the problem persists.
I am attaching the html output of powertop that shows that powertop works properly (but does not displays properly in the terminal).
