When I intially dock my T430 on a Series 3 mini dock, everything functions properly. Mouse, keyboard and display work fine. After maybe 5-10 minutes the external display flickers black, the external mouse and keyboard stop functioning and it must be re-docked to solve this for another 5-10 minutes. Using a 90w power supply on the dock.
I've read disabling USB Root Hub in device manager may resolve this, but I've also seen several people say it does not work, and I do not have administrative rights so if there's a solution that would'nt involve device manager, or a more "for sure" solution as not to take up too much IT time.
