The battery is not new. And already reported by the Gnome applet as of lower
capacity. That plus the fact that one load holds for less than 2 hours, I
wanted to preserve the battery.
I know from other sites that when holding the battery in the laptop and
charging it it can help loading it only to 80%. Given the X60 is very hot,
and while plugged in it can get even hotter, that would be a last resort to
save some battery.
ThinkWiki has been of great help so far. They say tp_smapi module would have
the said functionality. I downloaded that and compiled it.
FATAL: Error inserting tp_smapi
(/lib/modules/3.2.0-58-generic-pae/extra/tp_smapi.ko): No such device
So probably coreboot lacks the functionality. Any other way out?
