Thunderbolt port works only for charging T470s

2019-09-26, 21:33 PM

Recently I've bought a ThinkPad Thunderbolt 3 dock, but the only thing that works is that it charges my laptop. I have an external display connected and a mouse and keyboard, but non of them work. I assumed it is a driver problem, but I have all updates and fixes installed from Lenovo support page, but it still doesn't work. I have also installed Windows drivers for the dock and tried to run dock FW update tool, but it wasn't found at all. Also Thunderbolt Control Center app doesn't see anything connected to Thunderbolt port. Any tips on what could be wrong and how to make it work? This way, the dock is useless for me

Do you see Thunderbolt under Device Manager / System Devices?  There are a few options in the Bios setup pertaining to Thunderbolt and when to accept devices, turn on for booting or after booting, maybe one of those can be changed?

I can't comment on that, becasue in the meantime, my laptop died and it seems to be a motherboard. I am currently waiting for the spares to arrive and get it services. Luckily it's still under warranty. Anyway, if the MB is changed and system reinstalled, there is no way it could not work. So I hope.
