Problem is, if he desolder the dGPU how do we know which pin goes where? Do the PCIe signals go directly on the GPU chip or do they go on a different place on motherboard? (schematics are not very clear).Ĭan we find the pinout/datasheet on an 7670m card? He is willing to desolder his dGPU from the laptop in order to connect an eGPU riser (got his idea from here). To summarise, he is using a modded bios with the ability to enable/disable dGPU/iGPU. I had a private conversation with AGmR about his request. If have an Elitebook/Probook then is virtually impossible to get that functionality.
Can try to modify UEFI variables as described at OR get a modified/unlocked BIOS that allows setting the PEG variable. If your dGPU port is locked, then need a strategy to enable it.
