This is noted in the Shutdown Article at http://www.aumha.org/articles.htm
When I do shutdown, the computer shutsdown but doesn't give me the prompt "safe to turn monitor off". When I looked at computer, it shutsdown but doesn't shut off. I have used the recovery disks, but that doesn't help. Its like it is in standby or hibernate mode all the time. I updated drivers from MS, it worked for awhile, then it stopped again. Thus, I have to manually shut the computer off every time that I am using it. Please, somebody help me!!!
