I've never gotten useful results from powertop. The model it builds to correlate system events vs. observed power usage always diverges with reality very quickly. In the good case it'll just do something a little silly like conclude that the CPU fan is the ultimate source of all power consumption. In the bad case it'll be something like think that a pair of linux veths uses 3kW (not a typo) of power.
- Svenstaro 11y agoI've gotten pretty good results on my all-Intel laptop.
- _yy 11y agoThe estimates may be off, but the raw data it reports (context switches, wakeups etc.) is accurate.

- jkot 11y agoI have good experience with powertop.
- smcl 11y agoI was the same - mixed results at best. I figured that manually playing with this all the time was the wrong solution and installed TLP instead which seems to work pretty nicely. Not sure if it is mentioned in the linked article, so if not then check it here: http://linrunner.de/en/tlp/docs/tlp-linux-advanced-power-management.html http://linrunner.de/en/tlp/docs/tlp-linux-advanced-power-man...
