I noticed that you also made a post about your mouse acting up. I want you to
try a different mouse and see if that gets rid of both problems. Your system
has been designed to "wake up" from standby when a button is pressed on the
keyboard, or if you moves your mouse. If you mouse is bad and going
"haywire", then it is probably waking up your system when you are not using
it. A new mouse will probably sove both issues.
Good luck!
