Date / Time Problem Surface T112 Board

Hello, when I reset the time / date, the time from the Surface does not continue. As an example I set the time to 19:00, then the Surface stays at 19:00 and MixRack and Touchscreen keep running (see photo). The mixer works so far, the memory battery of the Surface is ok > 2.5 volts. Anyone have any ideas?

i have same problem but in the idr mix rack…battery backup is >2,5 volts but it lost some fluid…

have i to change the varta battery?

You should change them

… to my problem mentioned above. This is a contact problem. After transporting the T112 the error was gone, now it’s back.
