I will show you how the controller unlocked the AS10D81 battery of the ACER laptop, which was locked and did not work for more than 3 months. I will show and tell you what I did with the battery and what helped me to restore the laptop battery and how I managed to trick the bq20z955 controller of the BMS battery board to restore the laptop to battery life.
