Hy guys, i have this lenovo TB-X605F with charging problem, the tablet is fake charging, i have replaced the charging connector twice, it only draws 0.40 Amps when pluging the cable for the first time then it stops drawing any Amps but the tablet keeps showing the charging image at 0% as long as i keep it connected. I have no voltage at the battery connector with the cable pluged, but i have 5 volts after usb connector on some testing points on the board.

On PCB search IC fusb252umx ( it is under plate cover) near USB-C connector)
