My Framework 13 - AMD 7040 Series doesn't boot when it is connected to HP Thunderbolt Dock G4

As the topic states my Framework 13 - AMD 7040 Series doesn’t boot when it is connected to a HP Thunderbolt Dock G4.

Observation:

  • The light on the power switch is on
  • I use the upper left port (Port 1) with an USB Type C expansion card
  • The little power indicator light is on
  • The screen stays black
  • When booting disconnected and connecting it, when windows is up, it works

Laptop:

  • Framework 13 - AMD Ryzen 7 7840U w/ Radeon 780M Graphics
  • 64 GB RAM
  • BIOS-Version: INSYDE Corp. 03.18, 08.01.2026
  • Driver-Bundle: v2.07 (2025-11-20)

Docking-Station:

  • HP Thunderbolt Dock G4 (120W)
  • Firmware: 1.5.29.0 Rev.A (20.11.2025) - this is the current version

I tried to disable booting from USB-Devices - a quick search online suggests that this might help - but it didn’t.

Does anybody have other suggestions? How can I investigate the problem further?

Thanks in advance

Robert

It’s a known bug in BIOS 3.18, but still no fix available. Downgrade to 3.17 and your laptop will boot again.

Thanks Mathias .. i try to downgrade and test again, when the next bios is published.
