I have an x250 notebook.
Capacity of my internal battery flows down. Some time i opened lenovo power manager and checked battery. Internal battery is full charged with 12,18V, but external battery is full charged with 12.68V.
It is very strange for me. As i know there is no li-ion battery with <4.2V full charge.
I recalibrated the battery, no changes.
Ok, It is possible that one li-ion battery has lower voltage then other two ones. I checked the voltage - 4.07. 4.07, 4.05 it is great result!
Batteries are not charged fully, so capacity is lower then it should be.
I found battery FW update for some lenovo notebooks, but i didn't find it for x250.
Can you help me?
