AMD Radeon 7400 not working!!

[vrkrathees]

Hii I own a HP dv6119tx notebook pc with amd radeon HD 6490m. When i upgraded my OS from Win 7 HomeP to Win8 pro the graphics changed to HD 7400m and its not working. When i check through the device manager it shows an yellow exclamation mark on amd driver. when i try to update driver it tells windows already installed the latest driver. I then tried the amd auto detect tool to update the driver. But the downloaded file wont run in my system. So now how i make my amd gpu work and get switchable graphics

Hi:

Use the W8 amd graphics driver from this model.

Uninstall any drivers you have tried first, and reboot before installing this driver.

This package provides the AMD High-Definition (HD) Graphics Driver and Catalyst Control Center for supported notebook models that are running a supported operating system. For notebooks with switchable graphics modes, this package includes drivers for both graphics processing units (GPUs). Switchable graphics enable users to switch between a power-saving graphics mode (normally used under battery power) and a high-performance graphics mode. If high-definition multimedia interface (HDMI) video output is supported, this package also installs the HDMI Audio Driver.

File name: sp59850.exe

Yes, that is correct.

Uninstall what you see and install that driver.

That is the only driver that will work since it was a custom driver made by Intel/AMD for the specific switchable graphics setup in your notebook.

You will never be able to update that driver, and I am not sure that driver will work if you decide to upgrade to W8.1 or W10.  I doubt it will.

The driver from AMD won't work because that would be for a model that did not have the Intel/AMD switchable graphics.
