    Hello everyone!
    There is a laptop-transformer Asus T302S.
    The device is 5 years old, the flight was normal until the docking station, aka the keyboard, failed.
    When the tablet is placed on the dock, it emits a connection sound, but there is no charging, the second battery is not detected by Windows, the keyboard and touchpad do not work. Working only USB sockets
    I assumed breaks in the cable "dock board - tablet socket", checked with a tester, everything is functional
    Yesterday I disassembled the dock, the battery (three cells 3.34 A / h) is alive and normal, it has 12.3v, there is no discharge current, there is no charging current either.
    In the photo 6.5 - minus batteries, 4.3 - controller outputs, white and yellow, 2.1 - plus batteries
    The charge voltage appears for a short time, for 5 seconds, when I touch the plus and the battery controller with the V tester. There is no indication of charging.
    The dock from the second T302 laptop works fine with this tablet.
    What do I need to check or replace?
    I am grateful to everyone for the helpful advice!
    I beg your pardon, English is not my first language
