Impact: > On hybrid graphics systems (AMD 6600H + NVIDIA RTX 3050), dropping below the UPower low-battery threshold forces the GPU into the P5 power state. Reconnecting the AC adapter fails to trigger a daemon re-evaluation, leaving the GPU permanently underwattaged. Steps to Reproduce: Disconnect AC power. Allow battery to drop below PercentageLow in /etc/UPower/UPower.conf. Observe GPU throttle to P5. Reconnect AC power. GPU remains in P5. Workaround / Proof of Concept: I have engineered an event-driven C/udev patch that intercepts the AC reconnection event and triggers a targeted systemctl restart nvidia-powerd to force re-evaluation.
