    Lenovo ThinkBook 16P g2 ach

    Hello, I have a motherboard from a ThinkBook 16P g2 laptop
    ryzen 7 5800h, rtxx 3060
    board model: bm5070 v1.4
    Serial:PF38FBT5

    The battery transistors burned out (Appendix 1), I removed the short circuit and connected the paths. I replaced the KBC with an unprogrammed one because I heard that it should program itself. Currently, the board consumes 0.002A on the laboratory power supply. and power light is on. The question is whether the laptop should run on the lab power supply or needed oryginal charger​? Is KBC to blame? Or maybe it needs to have battery charging mosfets?
