How do I achieve a working switchable graphics install and config on a ThinkPad W500 running Windows 7 64-bit RTM?

How do I achieve a working switchable graphics install and config on a ThinkPad W500 running Windows 7 64-bit RTM? I'm having ongoing graphics driver issues with my ThinkPad W500 running Windows 7 Home Premium 64-bit RTM. In summary, I have not had success getting the switchable graphics to run properly.

"After re-reading my question I was reminded of step #4:

Ran the Lenovo ThinkVantage System Update utility and select the ""ThinkPad Video Features (Switchable Graphics) for Windows Vista 64bit"" driver, which (interestingly) proceeds without error...

Realizing that the unattended/silent install worked (since that's what the System Update utility does), I ran the driver install in unattended mode rather than the default interactive mode:

setup.exe -install

I rebooted when it completed and it worked!"
