Found it on a Dell Latitude ATI Mobility M7 as others have mentioned. Just attaching to this thread to I get updates. Thanks all! I appreciate doing a google search and finding that others have grabbed the bull by the horn. This is a significant problem. Just speaking from a pragmatic standpoint (stepping back from HOW to properly fix it), my laptop is basically unusable as a laptop. I can use it as a desktop, but one which I can't easily shut off the monitor.
