Windows may automatically uninstall discrete GPU drivers on gaming laptops left in Eco mode for extended periods. This occurs because the OS treats an unused dGPU as a disconnected USB device, triggering a maintenance task that removes inactive drivers.
A pnpclean.dll system job typically removes driver packages after a 30-day timeout, though one ASUS ROG Zephyrus G14 user reported removal after just 15 days. Affected systems replace NVIDIA or AMD drivers with the generic Microsoft Basic Display Adapter.
This behavior forces users to reinstall drivers when switching back to high-performance modes. To prevent this, users can modify the Windows Registry or periodically switch from Eco to Hybrid mode to ensure the dGPU remains recognized by the operating system.
