I have an ~ 1 year old Lenovo G770 (quad core i5, 6gb ram, 750 gb hd and 2 graphics adapters: the onboard Intel HD graphics chip and a higher performance discrete 1gb ATI Radeon HD 6650M video card).  Just this week I did a reimage from the factory restore disks, then upgraded it to Windows 8.  Now I'm having a bit of an issue with drivers for the ATI Radeon HD 6650M.

When I boot up, I get a Program Compatibility Assistant window for ATI Catalyst Control Center, and when I click the Get Help Online button, I'm told:

"At this time, Microsoft doesn't have hybrid graphics drivers for AMD parts on Windows Update, and they aren't available on the AMD website. You'll need to get a Windows 8 compatible hybrid driver from your PC manufacturer. If this driver doesn't exist, we recommend that you use a non-hybrid driver, which might result in some loss of performance or functionality. Most notably, the external monitor port won't function on some laptops."

I can't find a Windows 8 driver on AMD's site that will work for this card, and the Windows 8 drivers page for my laptop model on the Lenovo Support site only lists video drivers for the onboard Intel HD graphics chip.  I want to keep Windows 8 (I find the new interface paradigm intriguing), but I also want full functionality on my relatively new notebook.

I ran the Windows 8 upgrade advisor before purchasing Win8 and wasn't warned about any compatibility issues with the video card(s).

Can anyone help me find the correct drivers, or perhaps have an idea when/if such drivers for Windows 8 64 bit will be available, and from whom?

Thanks!

PS, there's also an issue with the Lenovo Energy Management, but the Program Compatibility Assistant doesn't bring anything up when I click the the Get Help Online button.

Really?  

I bumped my original message to which no one had replied to get it closer to the top and maybe attract more attention to it by those in the know.  In that bump posting, I made the non-controversial water-is-wet-fire-is-hot statement that Lenovo should have already released these video drivers (since the RTM version of Windows 8 has been available for more than 4 months) and the message is deleted?

Very nice.

No one knows anything about this issue at all?  

Hi gdsmithtx,

Here's a thread with a link to some modified drivers.  These might work for you.

Your post wasn't controversial, it was felt that it was just too soon to bump.
