    Hi there,

    I've had my T400 for about a month and a half now and it's working great, with one exception. Can anyone help me out?

    I use an external monitor. When I unplug from the monitor, I cannot switch GPUs without first restarting the computer. The option is there in power manager like usual, and when I click to switch graphics, the screen goes dark (like normal) and then comes back on (again like normal). However, high performance graphics are still selected in power manager. Once I restart, the graphics switch no problem.

    Any ideas on how to fix this would be great. Thanks.
