Cannot access both AMD and Intel GPU devices

My DELL E6540 laptop has a Intel HD4600 GPU as well as an AMD HD8790M.

Before installing the HD8790M driver OpenCL programs could see both the CPU and the GPU device under the Intel platform.

After the install of the AMD driver the Intel GPU OpenCL is missing, and the Intel platform only shows the CPU.

Yet both GPUs can be seen with OpenGL/Cg programs.

Current driver versions are:

AMD 13.350.1005.0 (Catalyst 14_2_beta_1.3)

Intel 10.18.10.34496

I tried re-installing the Intel driver, also after a uninstall with Driver Display Uninstaller of the Intel driver.

Laptop has no BIOS options regarding video.

Help is appreciated to get both GPU devices accessible using OpenCL.

Sister thread at Intel forum Can't use intel GPU with OpenCL while AMD HD8790M is installed (where is suggested to ask here at the AMD forum.)

Hello same problem here withe the same laptop : Impossible to use the HD8790 nore switch to it, and games like Tomb Raider or Final Fantasy XIV A Realm Reborn are only running under the Intel HD4600 driver.

It's said that there is a switch option on catalyst, but not in my version : 2013 0314 1033 17070.

I tried both Dell's Ati driver and latest Amd's one. Still looking for a soolution.
