Vista Ultimate x64
W500 4058 CTO
When i try to change to high perfomance graphics, a bubble pops up saying:
"System cannot enable High-Perfomance graphics
Close any 3D or video applications and disconnect external displays. Then switch Graphics processors"
I have no programs open and No external monitors.
How do I solve this?

I think I am having a similar problem. It said I was using the ATI driver before now it is saying I am using the Intel driver. I'm not sure what I did but clairification would be nice. Maybe this is in the user manual have you looked online?

I reinstalled the ATI Driver, I notice after it asks me questions about my presentation settings it goes to another part that looks like a function key explanation but then the screen flashes and it moves to the next part of the setup. When I try and load the CC application it says that the module is not enabled.
Also, When I try and pull up the Lenovo power managment by hitting fn F3 it crashes with no error. Could this be the problem?
My configuration is the 406227U Vista 64 Ultimate.

I found the answer for me anyway at least to solve all my Vista 64 problems. I did all the windows updates but for some reason it did not update Vista to Service Pack 1. I went to the Microsoft's page and manual downloaded SP1 and it fixed all the driver and application problems I was having with power management.
Some program like Adobe Professional I had to reinstall after SP1 to get to work correctly but no run32.dll errors or balloon.dll probs.

You need power manager to work for sure. I am running Vista Biz x64 and Switchable Graphics work OK for me, although sometimes it has an issue and bluescreens the machine. Hopefully it's just driver immaturity and software immaturity and it gets better over time.
Theoretically x64 drivers should be *more* stable than 32-bit, but I have a feeling that the lenovo software doesn't get tested as well for x64 since it's not as common.
