    Has anyone had the black screen problem on T400? My T400 screen becomes black for 3-4 seconds after vista logon window before becoming normal. This only happens when I use ATI discrete graphic card. There is no such problem when using Intel integrate card.

    Though the black screen time is tolerable, it is very annoying. I already disabled TMM.
