    I have a dv6-6100 with an AMD HD6770m gpu and for some reason I can no longer access the catalyst control center on my laptop to change between gpus. Its almost as if its been unistialled. Ive installed the latest drivers for the discrete gpu and that did not fix my problem.

    Any suggestions?

    Thanks

    Ok so I'm having problems again with switchable graphics. For some reason I can only assign a GPU to programs not just switch it for full time use. So its basically an app by app basis. Now I tried to fix this by booting into my BIOS and making sure the switchable graphics was on "fixed', which it was. Then I went ahead and uninstalled the catalyst control center and re installed it. This did not solve the problem.

    Any idea how to get back to true fixed switchable graphics?

    Thank you!

    Sometimes these units have switchable graphics issues when using newer video drivers from AMD and will provide a warning during install that says something like “the graphic driver cannot be installed due to incompatible hardware on your computer." If you have done or seen this in the past and selected “ignore” during the install of the driver it has likely changed the device ID. The result is that the graphics BIOS functions no longer work correctly because it can’t match to the graphics ID. Just a suggestion…. but you might try this:

    - Confirm you have the latest BIOS via the HP support page for your unit.
    - Remove all the AMD drivers and devices (including all backup drivers, file folders, and registry references).
    - Re-BOOT the unit.
    - Install the last/latest driver that is offered via the HP support page (yes it’s old).
    - Re-BOOT

    If this works, you can then try manually updating the video driver to the latest via device manager while avoiding the new CCC. If during the driver install you get the device ID warning stop… unless you want to revert back to the old behavior. Also be aware that there are also sometimes driver compatibility issues between different versions of CCC… especially if they are years apart. Sucks they do that but it is what it is.

    Best, Dave
