Welcome back to the forum.
I am not a HP employee.
I would think you have some type of connection problem if you were certain the HDD was the only problem.
Double check all connections on the system board.
No power at system startup now means you have complicated a HDD failure problem.

I am not saying you caused the problem.
I can only guess you may have complicated a HDD replacement procedure.
Now the PC cannot startup.
Having this same startup symptom prior to replacing the HDD (which you did not state in your first post in this forum) may suggest you have a different problem.
I don't know if you created this problem when you installed a new HDD.
The startup problem could be caused by a different component if replacing the HDD did not fix the problem.

I pulled the hard drive from a tower that I am not using thinking that all is good. I know the hard drive is good, but now I can't get the all-in-one to start up. I have checked all connections and everything is plugged in that should be. I even tried putting the old hard drive back in and the end result is the same. I am wondering if the switch could be part of the problem. I don't know. I am now baffled. Pro tech time I guess.
