First what you must do, is checking your battery in another working laptop, or check another battery in your laptop. Then if all will be not ok, you shold wright here the measurements of all pins bq24735 when battery is connected, and we together will thinking what is the problem Sent boardview ---------- Добавлено спустя 11 минут 29 секунд: ---------- 1nteger писал(а): is short on two mosfets That is the problem, you need to fix this |
