Whenever I leave my computer on and come back to it I cannot get it to "wake up" from its energy saving state. Moving the mouse and tapping the keyboard doesn't do anything and the monitor stays blank. At first I though it was the monitor but turning it on and off doesn't help. When pressing buttons on the keyboard (like num lock) nothing happens so I guess its the keyboard and mouse. When I reboot they work fine its just annoying having to do so every time I need to use the computer (and it messes up downloads in things like eMule which take a while to get going). Any ideas on how to stop this?
