Writing bit 14 to 1 disables voltage and current Master. Unfortunately, once inserted back into the notebook, the battery didn’t work properly – the notebook would report full charge after five minutes of charging, and full discharge bbq2040 five minutes of operation on batteries, following up with an immediate shutdown.
