Gaming laptops have an ‘Eco’ mode, wherein they use solely the GPU built-in into the processor to save lots of power and prolong battery life. One consumer noticed that his makes an attempt to run completely in power-saving mode on an ASUS ROG Zephyrus G14 with an RTX 5070 Ti graphics card resulted in Home windows mechanically uninstalling the dGPU driver with none notification.
In response to Okay-Horse-3169, it took him months to resolve the scenario. Indicators of the difficulty embody the disappearance of the NVIDIA driver, the entry ‘Microsoft Primary Show Adapter’ showing in Gadget Supervisor as a substitute of ‘RTX 5070 Ti’, and errors. The consumer observed that Home windows treats the discrete graphics card as a USB system, which is disabled when not in use.
The system job pnpclean.dll removes the motive force package deal after a sure time frame. The timer is normally set to 30 days, however on the ROG Zephyrus G14 it is just 15 days. The laptop computer proprietor claims that “this may have an effect on any laptop computer the place you disable the discrete graphics card and depart it disabled for a number of weeks while in eco-mode”.
Okay-Horse-3169 has discovered a approach to verify that the motive force has been eliminated, in addition to to stop this from occurring. To detect the removing in PowerShell, enter the next.
Choose-String -Path C:WindowsINFsetupapi.dev*.log -Sample “(VEN_10DE|VEN_1002).*(was eliminated|timeout interval)”
NVIDIA graphics playing cards are recognized by VEN_10DE, while AMD playing cards are recognized by VEN_1002. If the phrase ‘was eliminated’ seems, Home windows has uninstalled the graphics processor driver. You’ll be able to forestall Home windows from taking this motion mechanically through the registry.

You too can manually allow the discrete graphics card as soon as each 14–15 days, however that is unlikely to be handy. It’s exhausting to think about why Home windows 11 behaves on this approach, because the profit is unclear while the hurt is apparent.
