What can I do about that? Another observation: if I connect a screen to the system's VGA port, when I call 'poweroff' the screen goes into power saving mode. This seems to indicate that the integrated video card is properly shut down. So the fans keep spinning, the LEDs keep shining, the LCD keeps displaying, but the video card is shut down? Might this help pinpoint the problem? Regards.
