I don't have a problem with ubuntu, everything is working fine, but I'm wondering if it can be more power-efficient.
For now I have installed tlp, powertop, and cpu-frequency-scaling-indicator. When all are set in power saving mode my laptop runs for about 2-2,2 hours. That's not bad (windows 7 isn't much better), but according to powertop and Power Statistics energy consumption is pretty high, 20-23 Watts.
Here comes my question. Can I do something more to decrease energy consumption? Or is this a normal consumption?
I'm using Sony-Vaio notebook with Intel i5 cpu and nVidia 310m gpu, system: ubuntu 15.10.
Thank you for help.

I'm sorry, I do not really get how text formatting works here.
