When you undock some models of Lenovo computers from the docking station with TurningPoint installed the computer may produce a Blue Screen and restart (or just restart)
Restart the computer and press F1 to get to the BIOS settings when the start screen displays.
Highlight Config and press Enter. Arrow down to Docking Station and press Enter.
Change “Legacy Devices on Mini Dock” to Disabled. Exit and save from the BIOS to boot the computer.
You should now be able to have TurningPoint installed and undock the Lenovo.
