Yep, that's the only way I can shut it down. I even did the hold the button down for ten seconds routine and then pullet the battery for ten minutes. No help. It seemed worse as far as freezing on windows edge, so I did a rebuild on it. No help. 'Bout ready to try out some of my home made 410 shells on it.
I'll give your advice a try, but right now I'm too pissed at it. Can't get this laptop to connect to my phone, either. Monkeyed with it for an hour and gave up before I launched it into the plaster wall.
