Hi, I have more or less the same problem with laptop-mode-tools. When I try to turn off my laptop, I get this message all on the screen continuing for ever and then, I have to press power button to turn my laptop off. I tried to uninstall or reinstall laptop-mode (which I am not sure if it was a good idea) and reinstall but but the same error message continues on the terminal forever... Thanks...
