Hey all! I’m looking to see if anyone else has had this issue as support has not gotten back to me yet.
Specs: FW laptop 16 windows 11
I recently installed a 5070 graphics module and I the laptop does not recognize the expansion bay. I am getting the grey screen with the warning “no expansion bay detected.”
I tried reseating the graphics module and interposer three times. I switched back to the old expansion bay module and it was detected right away.
I tried the new 4.0.2 BIOS update as well.
I have tried scanning for new hardware in the device manager as well.
Any more trouble shooting tips before I declare something wrong? I have seen one thread on this and one thread on reddit with little no solution.
Someone else had a recent situation I believe just like this and the interposer that came with it was bad but the one from their 7700 adapter worked so they were fortunate to not be dead in the water.
It also might be notable that the expansion bay and graphics module have different interposers. I think your graphics module should have shipped with its own interposer (which is the same type of interposer for the 7700S and 5070).
Yes it did indeed. If I was a betting man I would bet the interposer shipped with the 5070 is dead. However I am upgrading from the stock expansion bay so I can’t try out the old interposer as you say.
I’ll update everyone when support gets back to me. Hoping it’s just a bad interposer and not a bad expansion card.
If you have a multimeter on-hand you could ring out the interposer pins. That wouldn’t test for something like a partially-damaged connection that creates some limitations to the sensitive PCIe lanes and… well, the best-case scenario would be that you’d know without a doubt there’s a problem with the interposer.
Oh, last thought: you tried the 4.02 BIOS (which is a hard requirement). Did you also install the new driver bundle? You have to install BIOS 4.02 or newer (there’s also a 4.03 beta release) and driver package 3.01 or newer (there’s also a 3.02 beta release).
