I have a desktop with no touch pad, but for keyboard this is what I did.
Clicked on the arrow on the left of keyboard, brought down my specific keyboard
Right clicked on the keyboard
Right clicked properties
Then the box allow to wake was checked
I cannot guarantee that it is there for touch pad, but it is there for keyboard.
Experiement a bit you will find it for keyboard, then it will be similar for touch pad. Experiment you will find it and be able to change it.
