I contacted Lenovol support and they send me a replacement unit. The the replacement unit has the same problem. Thinkpad Thunderbolt 3 docking station does not charge Thinkpad P51 battery. I need to plug in the power adapter for both docking station and notebook. Does anybody have similiar problem?

Everbody's p51 would be the same. The thunderbolt port won't work as a charging port. The thunderbolt specs specify 100w max. That's not enough. Your thunderbolt port is not for charging. To charge via the dock, you need a workstation dock, not a thunderbolt dock. A thinderbolt dock can charge things like an x1 carbon (5th gen) or x1 yoga (2nd gen)

the Yoga does NOT have a "workstation dock". It has the USB-C dock. Also, I've deployed dozens of Yoga 370 with the USB-C docks configuration with varying degrees of success. Some users dock charges their machine, for others it doesn't. I've upgraded the BIOS and the power management software on the ones that don't charge but they still do not charge. Lenovo really needs to gets its act together in providing a real solution.
