Prakash,
That did nothing. I have all set to Never but still after a minute (I timed it) of inactivity the screen first goes to the Welcome screen and after a few seconds blacks out. I do have a second monitor but even with it disconnected the laptop acts the same. Used to be that with the monitor connected the laptop would never to to sleep and with the monitor disconnected this would occur with the laptop. I always have the monitor connected to have a 24" viewing surface vs a 15". I would just notice it going to sleep after a minute when I traveled with the laptop and didn't do much about it. Now it's happening whether monitor is connected or not. I am wondering if some app is doing this but can't determine which. I have ESET security but don't see anywhere there that would make this happen. I even tried looking at the event logs but the only thing I saw was some activity in Microsoft Security Audit when it went to sleep.
