I upgraded to Win 8 from 7, not through a fresh install and some months now I've noticed that I can't wake up my computer by any means except by pressing the on/off button. After researching extensively on line, I still can't find a solution. Please note that this issue was not present with Win 7 I'd appreciate your guidance.
