Model: 20823GF, with Intel/ATI 3650 graphics. Win 7 64 Bit or Win7 32 Bit, or Win Vista 32...
Was a custom load/install (Win7 64) when I purchased it, not a Lenovo load.
ATI & Intel show in the Device Manager. ATI shows as not being able to start (Code 10, sometimes Code 43) - in Windows 7 OR Windows Vista SP2.
BIOS settings set to Switchable. If I change to Integrated, machine boots fine and loads Intel drivers. Set to switchable, loads the Intel drivers, but no option to switch in Power Manager. If I change to Discrete, machine will Blue Screen, indicating that the driver is caught in a loop.
Installed latest Win7 ATI switchable drivers per the Lenovo site.
ATI drivers work fine if I set to Discrete and install Windows XP.
Motherboard was just swapped out under warranty - I'm thinking this is only a coincidence, but worth noting.
Yes, I realize that there are heaps of threads on the discrete graphics issue, however none seem to resemble the issue that I am having.
Before you note that I should load/restore the Lenovo image - I can't right now, as the disks were damaged and thus I am awaiting new ones from Lenovo.

Anybody? Lenovo told me to reload the machine with the recovery DVDs; which I have done; however I am still getting an error code 43 for the ATI video card, and the ATI card will not launch in discrete mode.
Help! Is anyone reading these?
