[SOLVED] TH3P4G3 eGPU not working standby light and both Thunderbolt ports not working

  • 13 inch AMD 7640U laptop.
  • TH3P4G3.
  • 500W “be quiet!” working PSU and an RTX 2070 card connected to it.
  • Device manager shows I got Thunderbolt 3 and USB 4 Drivers but not Thunderbolt 4
  • Device manager “System Devices” does not show any Thunderbolt controllers

I have tried restarting the LapTop with both ports and the eGPU LEDs indicate STANDBY. Also have tried connecting to an intel laptop with thunderbolt 3 ports without luck.
A new Thunderbolt cable is on the way to rule that out.

When connecting the non-power delivery thunderbolt port to the laptop I hear a usb connection notification, the device-manager reloads but nothing appears. I have tried “Show hidden devices”.

When connecting the power delivery port to my laptop the connection notification sound does not play. The device manager is stuck in a loop reloading the items as if there was a hardware change.

Until now I haven’t been able to see anything under Display adapters.

More stuff I did:

  • Installed Thunderbolt Control Center (did not work)
  • The “about” page shows that I have no thunderbolt controller driver (did not work)
  • Tried installing Intels controller driver (did not work)
  • Can’t find a driver for AMD (there is none)

Any help would be nice. The only reason I got a Framework is because I could get the flexibility/upgradeability of a PC in a laptop, that includes gaming with a GPU.

SOLUTION
Apparently it was a problem to do with the 8-pin “CPU” connector to enable power delivery through the eGPU which did not work.
Disconnected the 8-pin cable and connected the Thunderbolt cable to the non-power delivery port and everything works.
Also the power delivery port does not work. It gives me a green light and powers the GPU and PSU on and off in an endless loop.

Interesting. Under Linux I have no issue getting the TH3P4G3 working via its PD port - I get both power and a Thunderbolt link with any card working just fine - so it’s not an issue with the dock design itself.

Are you on the beta bios?

While in my case the th3p4g3 did work on the power delivery port without it I am not sure I have ever tested it at less than full charge so the PD bug may not have triggered.

Is this the beta BIOS?

Also my laptop does not start any USB devices. I have to disconnect and reconnect them after starting to get them to work. Any suggestions?
