Same issue. Behavior:
A normal shutdown is initiated (via the desktop environment's shutdown menu). All applications and the session close normally, and the screen goes blank as expected. However, the laptop's fans and power continue running with no display output. The system does not respond to the power button being pressed briefly; holding it for ~10 seconds forces a full power-off.
