T520 (4239) + minidock 3 + keyboard logitech illuminated



when i start my T520 and is connected to minidock3 than is my keyboard complet without function.

i need the keyboard for type a password in TrueCrypt or change bios settings.

when windows is startet than the keyboard has normaly function.

The illumniated keyboard is running on a older dockingstation with a T500 without Problems.

A older and very simple keyboard from Logitech is running correct, i can change the bios settings and type the password.


can you help to find a solution for this problem?


the bios is the newest from lenovo.
