One thing I realized is that I accidentally posted the wrong laptop. It's an Envy dv7-7240us, not 4000. I keep getting the numbers mixed up for some reason. Sorry about that. The video you showed me was for a Pavilion. Similar, maybe, but it didn't show me why my keyboard keeps getting stuck in the middle. In fact, it even skipped the part showing poking in the DVD tray and starting at one corner and prying it up.
Is there anything in the middle of the keyboard that would keep it from coming up?
I've taken apart and put together desktops before, but this is my first laptop, other than inserting memory and new SSD drive. Not 100% sure of what I'm doing.
I appreciate the help, but so far, it's not quite what I need.
