Problem with batteries in Medion Akoya PT2214

[bezelex]

hello, I would like to ask about the batteries in medion akoya pt2214. As you know, there are two batteries, one on the tablet, the other on the dock / keyboard. In the attached picture you can see that the first battery (the one on the tablet) is charged and the other one is 0% and I can not charge it. I was looking for drivers, ways but I found nothing. Are I going to do something about it? Why is this second battery in the dock / keyboard like it can not be used? I would ask for some point
