I got a laptop lenovo ideapad 320-15isk with board number NM-B241 for battery replacement but after changing the battery i am getting battery 100% only. So for confirmation i trued 3 battery but same result. On newly formatted hard disk and in hiren it is showing 100% as well. So i get confirmed the issue is related to motherbard. First i updated the bios from lenovo website but same result Second i change the discharging mosfet and clean the charging ic but still same. So i decided to take help from group and arun sir guided me with following: 1. Clean me the bios if intel.. 2. Go to THINKVANTAGE and scan battery health.. lf bad replace it. If good reset the battery settings there. 3. Before confirmation the above things don't touch the motherboard parts. So i tried clean me and checked but still same. After that i installed the " Power Management Driver" and "THINKVINTAGE". After restart my problem is solve.
