Power Saving Woes: Long Battery Saver Usage May Cause Win11 to Silently Remove GPU Drivers

Summary

A recent Reddit post by an ASUS ROG Zephyrus G14 user highlights a serious issue where Windows 11 automatically deletes the discrete GPU driver after prolonged use of power-saving mode, preventing the user from switching back to performance mode for gaming. The user's laptop, equipped with an NVIDIA GeForce RTX 5070Ti, had been running in energy-saving mode for several weeks. When the user switched to performance mode, the system no longer recognized the GPU, listing it as a generic display adapter. The root cause is attributed to a Windows 11 maintenance task called pnclean.dll, which cleans up drivers for devices that have not been 'connected' for 15 to 30 days. On laptops with a MUX Switch, power-saving mode disables the discrete GPU entirely, causing Windows to treat it as disconnected and remove its driver, similar to an unplugged USB device. This issue has sparked concerns among gamers and laptop users, as it could affect all hybrid-graphics laptops. The impact is significant: users may face unexpected driver reinstallation, system instability, reduced gaming performance, or even mistakenly believe their hardware is faulty. Microsoft has not yet provided an official response, but the community has been sharing workarounds, such as customizing power plans, disabling GPU power saving, or blocking driver updates. This incident underscores the need for Windows 11 to improve…
