Thinkvantage detected wrong GPU, installed wrong drivers, can't undo?

So I have a T400.  P9400, Radeon HD3xxx (forget specifically), 4gb ram, other what nots.

 

I recently installed win7 over vista, and when I ran thinkvantage to automatically grab all my drivers for me it installed drivers for the intel chipset graphics, rather than the better ati graphics.

 

When I go totry and install any ati graphics it constantly tells me its not there, and under device manager it says only the intel chipset is present.  There is nothing under the install/uninstall menu for me to get rid of the drivers, so I can't uninstall those and install the ati ones over it.

 

What makes this ridiculous is that when I first checked thinkvantage it told me that I had an ati card without drivers, and that I should get them.

 

However it never installed them, now it cant find it, it says everything is great, and this is REALLY starting to piss me off.  What do?

did you have the intel gpu activated rather than the ati graphics card activated?

I can't say I have any idea of how to enable either one.

you can change the gpu through the Thinkvantage Power Manager, under the different power plan.

Okay, so, installed power management, didnt help with anything, went into bios and disabled switchable graphics

 

It picked up my 3400 just fine and it works, so now the problem is that the switchable graphics arent working?

I had this problem when I upgraded to Windows 7. After I did system update, I manually installed the driver from lenovo and it worked fine for me after a restart. This should be the driver
