HP Dragonfly G4 – Critical USB-C / External Monitor Issues After sp170029 Update

[swe124578]

Hi,

We are experiencing a major issue with a fleet of HP Dragonfly G4 devices and are hoping someone at HP or in the community can provide guidance.

Environment:

~40 devices
HP Dragonfly G4 (i7-1355U, 32GB RAM, 1TB)
Purchased December 2024

Background:

Shortly after deployment, we had significant issues with the webcams. After extensive troubleshooting together with HP (including log analysis), it was identified as a driver issue and resolved with an updated driver.

Everything worked fine after that.

Current issue:

About two months ago, we installed an update via HP Support Assistant:

sp170029.exe

Shortly after this update, we started seeing major issues with external displays connected via USB-C.

Symptoms:

Works fine after a reboot (e.g. first login in the morning)
Stops working after a while or when disconnecting and reconnecting
No signal to external monitors

In some cases:

USB devices (keyboard/mouse via dock/monitor) stop working as well
Occurs regardless of:
* monitor
* dock
* user

All ~40 devices are affected.

Impact

This is a critical issue for us. Our users (lawyers) rely heavily on external monitors and are currently unable to work properly.

Observations

Issue appeared directly after installing sp170029.exe
Behavior points to a USB-C / graphics / docking-related driver or firmware issue

Consistent across the entire device fleet

Questions

Has anyone else experienced this after installing sp170029.exe?
Is this a known issue from HP?
Has this update been pulled or replaced?
Is rollback recommended, and if so, which driver should be targeted?
Any known workaround or fix?

Happy to provide logs or more details if needed.

Thanks in advance.
