Just did a clean install of Vista Business 64 and the switchable graphics don't work (stuck in Intel, ATI has yellow !).
Help!!!

Yup, still have integrated graphics only, with yellow exclamation mark through the discreet chip in device manager and no switch option in power manager.

In BIOS, under configuration, video, check that "OS Detection for Switchable Graphics" is enabled, and that "Graphics Device" is set to switchable graphics.

I just spent two days wiping and reinstalling Vista Business 64 trying to get everything to work, but every time the switchable graphics would lock in Integrated and the menu wouldn't be on power manager.
I finally got it working (don't ask me how, no clue), but device manager still shows two items, PCI Serial Port and PCI Simple Communications Controller has not being configured even though I've installed everything on the Lenovo page except for some unwanted ThinkVantage apps (access connections mainly). All hardware works, so I have no clue what those last two items are.
This really takes something away from the joy of a new machine.
