Thanks! I figured it out. A carbon based error! The battery pack release on the back has two tabs that you spread to remove the battery. When you replace the batteries you have to push them back together.
There's a label on the back that says "Normal Operating Position" and has a picture of the tabs TOGETHER. I wasn't pushing the tabs back together. Duh!
I did find my HP J728 & NEC 900 in my storage unit and I did mange to get them started! Now it's off to Wally World for some more AA and 2032 batteries!
