It goes to the text screen, where it says it is stopping services etc., but then hangs....if I haven't noticed, the battery eventually runs out. But I can force it to shut down by holding the power button. Maybe there is some funny bug in the shut down procedure? </blockquote></div> I've had this problem a lot on my desktop PC - I hear the disk drive stop, but I need to press and hold the on/off button to switch it off. Sometimes I get a full shutdown. Of course, its not on battery power :)
