Diagnostic step 1
Collect diagnostics before making further changes: run nvidia-smi -q (from an elevated PowerShell with NVIDIA tools if available) and capture Event Viewer logs (Display and System) covering the timeframe when symptoms started.

NVIDIA driver update leaves laptop GPU busy: 100% fan, high battery drain and persistent nvcontainer GPU usage
Generated Oct 3, 2026, 12:35:03 AM
Analysis summary
Persistent GPU usage by nvcontainer and display driver warnings after update indicate the driver or its system services are holding the GPU in a high-power state. Root causes include driver bugs (resource leak or mis-set power-management state), background NVIDIA telemetry or helper services incorrectly querying/locking the GPU, or incompatibility between OEM firmware and new driver power-management defaults. Device Manager 'disable' shows the display stack depends on NVIDIA drivers for external monitor routing, explaining continued issues after partial removal. Full, clean removal using DDU normally reverts behavior; however, stubborn services or Windows update driver reinstallation can reintroduce problematic driver.
Possible causes
New NVIDIA driver contains a bug that prevents proper GPU power state transitions, leaving GPU in P0 or high-performance state.
90%Driver/firmware incompatibility with OEM power management or hybrid graphics switching (Optimus) implementation.
85%NvContainer or telemetry service actively uses the GPU for hardware acceleration (e.g., NVENC/decoding) due to telemetry or background tasks.
80%Incomplete driver removal left mismatched components (services vs kernel driver) causing inconsistent state.

Diagnostic step 2
Fully remove NVIDIA drivers using Display Driver Uninstaller (DDU) in Safe Mode, then reboot to Windows Update 'Optional updates' and explicitly hide NVIDIA driver updates (to prevent automatic reinstallation) until you have a working version.

Diagnostic step 3
Install a known-good older driver from NVIDIA download archive (not GeForce Experience auto-installer). Prefer OEM-recommended drivers if the machine vendor provides a tested package.

Diagnostic step 4
Temporarily stop NVIDIA services (nvcontainer, NVSVC) to confirm they are the source: set service to manual and stop them; if fan/noise reduces, collect which service was responsible. Avoid permanently disabling services without understanding side effects (external monitors or CUDA workloads may break).

Diagnostic step 5
If symptoms persist after clean reinstall, capture ETW traces or use Windows Performance Recorder to profile power state transitions and GPU power usage. Provide those traces and logs to NVIDIA or OEM support for escalation—this is likely a driver/firmware interaction that may require a vendor patch. If you are uncomfortable with kernel/driver rollbacks, escalate to vendor support for guided safe rollback and firmware checks.
