I just acquired a (used) Thinkpad tablet dock, for my helix 2.
However, it disconnects everything when i connect a power plug - USB, HDMI etc. It doesn't matter if the power plug is connected to power - its simply plugging it in the dock, that causes this.
I can charge the tablet with power connected - but i simply cannot get everything connected simultaneously.
I have tried with both the Helix 2, and a thinkpad tablet 10.
Any suggestions on what migth be wrong?
EDIT: Fixed it with a new charger.
Thinkpad T61F 14" (2.53 GHz QX9300, 6 GB RAM, Quadro FX570m 256 MB, SXGA). Advanced dock with AMD Radeon HD7750
Custom build ITX desktop (i5 4590, 8GB RAM, AMD R7 260X, custom watercooling)
Thinkpad 8, Fujitsu F-07C
I have a Thinkpad Tablet 10 Gen 2 that wouldn't see any of the ports in a dock, so I returned and got a new dock - which still didn't work. I assumed than that my tablet had a problem, and ended up finding another tablet to try - with still no luck using any of the USB ports, Ethernet, audio or HDMI. Power would go through and charge the tablet though. I tried replacing drivers, reloading the chipset driver, reloading Windows 10 - no luck.
After seeing this thread - I grabbed a 90W power supply I had laying around, and everything worked! Based on that, I would say that the 45W power supply is not powerful enough for the Gen 2 tablet and dock together - since it didn't work with 2 different docks, power supplies and tablets combined.
Hopefully someone finds this information helpful.
