Dear community
I have a new Surface Book (i7, 512GB, with the Nvidia GPU in the base) and encountering the following strange behavior: when the tablet is connected to the base, the base battery is charging fine but not the tablet battery. When I disconnect the power supply
from the base, the tablet battery switches in to the status "charging" and it definitely charges. As soon as I reconnect the power supply to the base, the charging of the tablet battery stops again. When I detach the tablet and connect it directly to the power
supply, the tablet battery is also not charging. As my English is not such good, I took some photos to illustrate the problem:
Tablet on the base, base connected to the power supply, white LED is visible: base battery is charging but not the tablet battery:
When I detach the power supply from the base the tablet battery switches to "charging" and starts to charge:
When I detach the tablet from the base and connect the power supply directly to the tablet, the tablet battery is also not charging:
What I have done so far: complete re-installation of Windows 10, installed all Windows updates, no additional software or peripheral devices installed / connected, uninstalled the battery drivers, cleaned all connection plugs, run the MS Software Repair
Tool. Everything without success. So the situation is still: the tablet battery is only charging (from the base battery), when the base is not connected to the power supply.
Maybe someone has the same issue or an idea what else I could try?
Thank you very much for your help!
