[Lenovo non-ThinkPad series] Battery conservation mode threshold is different on some machines
Root-Core opened this issue · 7 comments
TLP references the Battery Conservation Mode to have a fixed threshold of 60%.
Newer laptops - or some - have 80% as their target. At least my does and some others.
It seems there is no way to read out the actual target.
Therefore TLP should avoid mentioning the 60% - or any - threshold, as some hardware configurations have different thresholds.
I had the idea to map the battery or laptop models to a threshold, but that can get complex quiet quickly.
Maybe there is another hint that could be used like the capacity etc. but this might be out of scope for TLP.
I also think it's a pity that there is no way to read out the actual threshold. I'll add a note on the website first and remove the percentage from the tlp-stat output with version 1.7.
@linrunner You might add to the comment in the docs, that the BCM does not discharge the battery to the fixed threshold automatically. You have to unplug until it's at/under the threshold.
@Root-Core it's already in the FAQ:

What charge thresholds do not do
- In particular, with AC connected, a battery with a charge level higher than the stop charge threshold will not be discharged to the stop charge threshold, nor will there be a (cyclic) discharge down to the start charge threshold
@linrunner My bad, I confused the TLP documentation with some other. I should have checked again, sorry for the inconvenience.
Thank you for the quick adoption and response.
