Powertop doesn't show any wattage numbers for me. I looked at gnome-power-statistics and saw that my laptop idles around 9 watts. That's all power consumption including the screen. This afternoon I upgraded my kernel from 4.15 to 4.18. Then I removed the r8168 module that I'd tried to use to reduce power consumption. Using the open source r8169 module got me PC7 states. Now my X210 idles at 5 watts. I'm guessing I could go lower if I tweaked more, but this is a huge improvement in battery life. I'm glad I took the time to look into it. I've gotten battery consumption figures as high as 30 watts when running something like `./minerd --benchmark --threads=8`. Intel claims the i7-8550U has a 15W TDP, but it can easily go above that if it has enough cooling.
