Same exact problem here except on a Dell laptop. In fact, if I have it in
High Performance, my computer won't even sleep if I hit the button or close
the lid.

Coincidentally, I have a few corrupted tasks in task scheduler that I can't
get rid of either. One was Scheduled Defrag, which I suspect is trying to
run and won't allow my computer to sleep. This is just a guess, because I
can't figure it out and it's really getting frustrating.
