HP ProBook 450 G10 Ethernet Not Detected Realtek Windows 11

The HP Dragonfly Pro running Windows 11 with driver issues is usually encountered when users install Windows 11 on hardware that was designed for ChromeOS or when HP Dragonfly Pro Windows variant drivers are outdated after a Windows 11 feature update. The HP Dragonfly Pro (Windows version) uses the same chassis as the ChromeOS model but comes factory-installed with Windows 11. I have resolved touchpad and audio driver issues on an HP Dragonfly Pro HPCM after updating all drivers through HP Support Assistant.

Why HP Dragonfly Pro Has Driver Issues in Windows 11

Drivers Outdated After Windows 11 Update

Windows 11 feature updates can replace manufacturer-installed drivers with generic Microsoft drivers. On the HP Dragonfly Pro, the Intel I2C touchpad driver, Realtek audio driver, and Intel WiFi driver are among those most likely to be replaced by generic versions after a major update. Generic drivers reduce functionality – for example, the touchpad may lose multi-finger gesture support when running the generic HID driver instead of the Intel Precision Touchpad driver.

HP Support Assistant Not Installed or Not Running

HP Support Assistant automatically monitors for and installs driver updates on HP laptops. If it was uninstalled or disabled, the HP Dragonfly Pro misses critical driver updates that HP releases specifically for Windows 11 compatibility. Some updates are only available through HP Support Assistant and not on the HP support downloads page.

Intel I2C Touchpad Driver Missing

The HP Dragonfly Pro uses an Intel I2C interface touchpad. The Intel I2C controller driver and the Precision Touchpad driver must both be installed for the touchpad to function with full gesture support. Without the Intel I2C driver, the touchpad either does not work at all or works at reduced functionality as a basic pointing device.

Fix 1 – Run HP Support Assistant for All Updates

1. Open HP Support Assistant from the taskbar icon or Start menu (pre-installed on HP Dragonfly Pro).
2. Click Check for updates and messages.
3. Install all available driver updates – particularly for audio, display, touchpad, WiFi, and chipset.
4. Restart after installing all updates.
5. Run HP Support Assistant again to confirm no updates remain.

Fix 2 – Install Intel I2C Touchpad Driver Manually

1. Go to HP Support and enter the Dragonfly Pro product number.
2. Select Windows 11 64-bit.
3. Download the Intel Serial IO driver or Intel I2C GPIO Controller driver from the Chipset section.
4. Also download the Touchpad or Pointing Device driver from the Mouse, Keyboard and Input Devices section.
5. Install the Intel Serial IO driver first, restart, then install the touchpad driver and restart again.

Fix 3 – Reinstall Realtek Audio Driver

1. On the HP Support page for Dragonfly Pro, download the Realtek High Definition Audio driver from the Audio section.
2. Open Device Manager, expand Sound, video and game controllers.
3. Right-click Realtek High Definition Audio and select Uninstall device, checking the box to delete the driver software.
4. Run the HP Realtek audio installer and restart.

Per Carolyn Ng, who is an executive using an HP Dragonfly Pro for business travel, running HP Support Assistant after a Windows 11 update found and installed 8 driver updates including the touchpad, audio, and WiFi drivers that had all been replaced by generic versions during the OS update – restoring full touchpad gesture functionality immediately.

Conclusion

HP Dragonfly Pro driver issues on Windows 11 are resolved by running HP Support Assistant to detect and install all available driver updates, manually installing the Intel I2C touchpad driver and Realtek audio driver from HP Support if automatic detection misses them, and keeping HP Support Assistant active for ongoing driver maintenance. The most important step after any Windows 11 feature update on the Dragonfly Pro is to immediately run HP Support Assistant to restore all manufacturer-specific drivers that the Windows update may have replaced with generic versions.
