As usual I hacked through it after I post for help. What I found was nothing that was posted on the Web. I've got a Intel graphics card and during the initial install Windows loads a generic VGA graphics driver. Well that didn't have provision for sleep mode on my machine. Subsequently I installed the oe Intel driver but for some reason it was getting trump by the native win7 driver. So I tried to disable it and it worked. However after getting rid of (deleting), it re installed back and the issue arose again. So if you just disable the driver instead of out write deleting it, it will cease to cause the issue again.
