Lenovo ThinkPad P16s Gen 3 AMD GPU Driver Error 43 Fix
Ryzen 7 PRO 8840U
AMD Radeon GPU
Error 43 on the AMD Radeon GPU in the Lenovo ThinkPad P16s Gen 3 AMD means Windows has stopped the device because it reported a problem. This appears in Device Manager as a yellow warning on the AMD Radeon Pro or Radeon RX discrete GPU. The fix requires a clean driver installation and BIOS update.
Use DDU to clean the AMD driver and reinstall from Lenovo Support
Boot into safe mode (Shift + Restart → Troubleshoot → Advanced → Startup Settings → Safe Mode with Networking). Download and run Display Driver Uninstaller (DDU) and select Clean and restart for AMD. After restart, go to Lenovo Support, find ThinkPad P16s Gen 3 AMD, and install the AMD Radeon Graphics Driver. DDU removes all driver registry traces that cause error 43 to persist across normal reinstalls.
Update the BIOS
Install the latest BIOS via Lenovo System Update or directly from Lenovo Support for the ThinkPad P16s Gen 3 AMD. AMD error 43 on Lenovo ThinkPad platforms is frequently caused by BIOS-level PCIe power management mismatches where the BIOS does not correctly signal the GPU power state during driver initialization. BIOS updates resolve this by aligning the BIOS AGESA version with the AMD driver power management requirements.
Update the AMD chipset driver
Separately from the GPU driver, download the AMD Chipset Driver from Lenovo Support for the ThinkPad P16s Gen 3 AMD. The chipset driver manages PCIe bus routing and power management for all AMD components. An outdated chipset driver on the Ryzen 7 PRO 8840U platform can cause PCIe enumeration failures that show as error 43 on the discrete GPU.
Check BIOS GPU switching settings
Restart, press Enter then F1 for ThinkPad Setup. Go to Config → Display and look for Switchable Graphics or Hybrid Graphics. If set to Integrated Only, the discrete GPU is hardware-disabled. Change to Switchable Graphics or Discrete Only. Save and exit. A BIOS setting forcing integrated-only mode causes the AMD dGPU to be physically powered off while still appearing in Windows with error 43 during initialization.
Run Lenovo Vantage hardware diagnostics
Open Lenovo Vantage → Device → Hardware Scan and run a GPU test. If the GPU hardware test fails after a clean driver install and BIOS update, the discrete GPU chip on the motherboard has a hardware fault. Contact Lenovo Support for warranty service. Error 43 that returns immediately after every clean reinstall typically indicates a hardware-level fault rather than a driver issue.
Zulkifli, Kuala Lumpur: “Error 43 on the AMD GPU of my ThinkPad P16s Gen 3 kept coming back after normal driver reinstalls. Running DDU in safe mode to fully clean the driver and then installing the Lenovo AMD driver fixed it permanently.”
Frequently Asked Questions
What GPU does the Lenovo ThinkPad P16s Gen 3 AMD have?
The ThinkPad P16s Gen 3 AMD (Ryzen 7 PRO 8840U) is available with AMD Radeon Pro RX 6500M or AMD Radeon 780M integrated graphics depending on the configuration. The discrete Radeon Pro is the GPU most likely to trigger error 43, while the integrated Radeon 780M remains functional as the iGPU during the issue.
Can I work on the ThinkPad P16s Gen 3 AMD while error 43 persists?
Yes. The Ryzen 7 PRO 8840U includes an AMD Radeon 780M integrated GPU that handles all display output when the discrete GPU has error 43. You will lose access to the discrete GPU memory and compute performance, but the laptop remains fully functional for everyday tasks, display output, and most workloads.
Does error 43 on the AMD GPU void the warranty?
No. Error 43 caused by driver or firmware issues does not void the warranty. If error 43 persists after clean driver installation and BIOS update and is confirmed as a hardware defect by Lenovo Vantage diagnostics, the GPU replacement is covered under the standard Lenovo ThinkPad warranty.
Should I use the Lenovo driver or AMD Adrenalin driver for the ThinkPad P16s Gen 3?
Use the Lenovo-packaged AMD driver from Lenovo Support for the ThinkPad P16s Gen 3 AMD. The Lenovo version is certified for this specific hardware configuration and includes power management tuning for the Ryzen PRO platform. Generic AMD Adrenalin drivers from the AMD website may cause instability or error 43 if they conflict with the ThinkPad BIOS power management.
