I have been using Battery charge manager for some time since i use my ntb often plug in for long time, and it was limiting my battery charge on cca 80%. But some time ago it stopped working and started charging battery to full extend. I have BIOS set to "let HP to manage my battery" and in power manager set option "Maximize my battery health" on. Yet still charge to full and can't find way to make it work. Any help is appreciated.
