I am posting in the hope that someone can help me. I have installed vista ultimate on my T400 and have managed to install most of the drivers however I am still haveing a problem with 2 icons in my device manager.
There is an exclaimation mark on my SM Bus Controller & I have 2 display drivers one is comming up as Stadard VGA which is fine but the Other is a Radeon Mobility HD 3400 which also has an exclaimation mark on it.
Could someone please help me resolve this issue.

I have solved the SM Controller problem, by installing the chipset drivers. However I still have the ATI Radeon HD 3400 conflict in device manager with the Standard VGA adaptor. The only way around it is that i disable the switchable graphics and only use descrete graphics. Is this the correct way to solving this or can someone please shed some more light on this issue.
