I found the thread " Inability of Computer Going Into Sleep Mode" which is closed but I have this problem. I did not understand the solution given.
I have new Toshiba Tecra with Win 7 . When I left the machine for 15 min, it went to sleep. I installed Norton Anti-virus. Now it does not go to sleep unless I manually select sleep from shutdown menu. I contacted Norton Chat and was told that Norton kept the machine awake for its protection, which is pointless because the machine is safe from virus when asleep.
I didn't believe what I was told so googled around and found this thread, but do not understand what I am supposed to do. Since I just installed last week, it seems pointless just to uninstall and reinstall.
Thanks for your careful attention to my problem.
