I get 3.8W on lowest backlight and associated wifi. 3.5W with deassociated. All the ASPM is enabled, but i still never reach pc9 and pc10.
Out-of-tree r8168 module is necessary for ASPM support.

As your LCD does not support PSR, then you will get pc9 only when the LCD is in DPMS off state (and wifi is disconnected).
You may start powertop, issue

Code: Select all

xset dpms force off
in separate terminal, wait a minute, press any key to wake the display and see results.

I've brought up some infra for comfortable patch selection and application: https://github.com/l29ah/x210-ec
It would be cool if you submit your patches/pull requests to avoid throwing lots of differing and poorly documented blobs around that bring a lot of changes and are a pain to merge.

Is it possible to set the bat thresholds with EC?
If you want to undercharge the battery to prolong it's life, then it may be done already. :-) At least my laptop is constantly undercharging the battery by several parcent.
My X210 charges the battery to 4.16 per cell, while ~4V ceiling during typical use would make more sense: it's only ~25% less energy but only ~20% cycle wear compared to 4.2V cycles, also less time-based degradation.
