Not sure if this question is proper for this group. If not, please help direct me to the right group.
Lenovo thinkpad provides a power manager software that allows for battery gauge reset. It's a hunch but it seems that there is a counting mechanism every time I "perform reset". In early days when I performed the reset, the battery life really seemed to be extended (e.g. from 1.5 hr to 2.5 hr when fully charged). Recently I made a mistake (?) by performing "several" resets in a row (when the battery condition was still deemed "good"). Suddenly after these resets, the battery condition changed from "good" to "fair" and the battery hours dropped significantly.
Is the battery gauge reset thing/button a software thing or a hardware thing ?
If it's a software thing, can we "erase" the counting (if any) and start fresh ?
Does reinstalling the power manager help (as Lenovo does provide a place to download the power manager) ?

Any info will be appreciated. Thank you.
