The HP ZBook Fury 16 G11 is a professional mobile workstation built for demanding engineering and creative applications. The NVIDIA RTX A4500 GPU is essential for rendering, simulation, and AI-accelerated workflows. When the RTX A4500 is not detected by Windows — missing from Device Manager or showing a code 43 error — GPU-accelerated work cannot proceed.
This guide covers the most effective fixes for NVIDIA RTX A4500 not detected on the HP ZBook Fury 16 G11 with the Intel Core i9-13950HX processor.
Why the RTX A4500 Is Not Detected
- NVIDIA professional GPU driver not installed or corrupted
- Device Error Code 43 due to a driver initialization failure
- GPU disabled in Windows or Device Manager
- Thunderbolt or PCIe link power state causing GPU to be unreachable
- BIOS update changed discrete GPU settings
Step-by-Step Fixes
Fix 1: Install or Reinstall the NVIDIA Quadro Driver
The RTX A4500 requires the NVIDIA professional (Quadro/RTX professional) driver, not the consumer GeForce driver:
- Visit the NVIDIA Driver Download page and select Product Type: NVIDIA RTX Enterprise, Series: NVIDIA RTX A Series (Notebooks).
- Download the latest production branch driver.
- Before installing, open Device Manager, right-click the RTX A4500 (or the entry with a yellow warning icon), and select Uninstall device. Check Delete the driver software.
- Install the new driver and restart.
Fix 2: Use DDU for a Clean Driver Install
If a previous driver installation is corrupted:
- Boot into Safe Mode.
- Download and run Display Driver Uninstaller (DDU).
- Select Clean and restart to remove all NVIDIA driver remnants.
- On normal boot, install the latest NVIDIA RTX A4500 professional driver.
Fix 3: Enable the GPU in Device Manager
The discrete GPU may be disabled:
- Open Device Manager and expand Display adapters.
- If the RTX A4500 shows a down arrow icon, right-click it and select Enable device.
- If it shows a yellow warning, right-click and select Update driver.
“A BIOS update had reset the discrete GPU setting. After re-enabling it in BIOS and reinstalling the NVIDIA professional driver, the RTX A4500 appeared in Device Manager immediately.”

Fix 4: Check BIOS for Discrete GPU Settings
HP ZBook BIOS may have a setting that controls discrete GPU availability:
- Restart and press F10 to enter BIOS.
- Navigate to Advanced > Built-In Device Options or Graphics.
- Ensure the discrete GPU is set to Enabled rather than disabled or graphics switching only.
- Save and exit.
Fix 5: Update BIOS via HP Support Assistant
HP BIOS updates for the ZBook Fury G11 can fix GPU power state initialization issues that cause the RTX A4500 to fail detection. Open HP Support Assistant, go to Updates, and install any available BIOS update. Test GPU detection after the update and restart.
