I've found this for IBM laptops : http://www.thinkwiki.org/wiki/Tp_smapi#Battery_charge_control_features The features exist in windows for Sony Vaio laptops as the users say here http://forum.notebookreview.com/showthread.php?t=288638 http://ubuntuforums.org/showthread.php?t=1225557 And it seems the same for Acer. But it is very strange that only some companies exposes such features. We can't find a way to do that by some reverse engineering ? How does the lm_sensors guys discovering sensors in laptops ? http://www.lm-sensors.org/ Any way, I always think that it can be controlled in some way, but we don't have a public api explained for that.
