    Asus Т302С docking station failed

    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

    It looks like you have checked anything possible. Unfortunately I can't assist with this, and there hasn't been any others either. This forum is in a kind of slump at the moment, as Asus hasn't really followed up with better or newer tablets, so people have started to leave this forum.
    I have a somewhat similar issue with a PC, not a dock, but it doesn't charge though the symptoms look a bit similar - flickering, then off. I found that a regulator (in my case one of those 6-pin tiny chips) was burned out, unfortunately replacing it didn't fix it so I'm still stuck.

    This is all very sad, the device was not massive. I ran into a problem in finding spare parts two years ago when the battery on another device failed. I was then lucky enough to buy it in China. Now, when the service support of devices is over, more and more spare parts appear on sale. I hope there will be blocks for my keyboard soon.

    How is the battery you bought from China?

    Tablets are subject to depreciation since some parts are turning obsolete. That's the reason why you can't find some spare parts.

    Yeah, I also encountered this kind of scenario. I went to a repair shop expecting my phone to be repaired but, it turn out that some parts are no longer in the market as there were no already production.

    Better buy a new one rather than letting the device be repaired. Most of the repair costs are costly, it would cost you lots of pennies and eventually after some time, it will be damaged again.
