I am looking for some help, I have a T450 that has been working away on a Thinkpad Ultra Dock with no issues, then all of a sudden it will not charge while docked!! Take it out of the dock and charge directly and it works fine, I tried replacing with a new docking station the exact model but again it does not charge the laptop while in the dock, I have switched out the battery and it is still the same.
I have fully updated the BIOS etc and still have the same issue, I tried updating the Ultra Dock firmware but run into issues as the firmware update will only run while docked and also has power, but as the laptop is not detecting power I cannot proceed , I tried updating out of the dock but it does not proceed either as it cannot detect the docking station.
Everything else works via the docking station HDMI, USB, DVI, Ethernet all working perfect, has anyone came accross this issue?
