A user reports that while driver version 595.71.05 previously allowed dual RTX 3090s to drop to 13-15W when idle, one card is now stuck at 24-30W with zero activity and fans off.
The issue persists despite stopping all running processes and having no monitor outputs connected. The user notes that power limiting via nvidia-smi is effective but only applies during inference tasks.
The author seeks a quick, safe method to reset the card's power state without requiring frequent system reboots.
