btw.........you will also need a #1 phillips screwdriver if you plan on removing the hard drive.

Today, while disassembling my HP 15-BA078DX I had an issue trying to get the shell apart. I didn't realize that there was a screw under each rubber foot by the hinges. It would have saved me a whole lot of trouble had I known that. Very important to get those 2 screws out, otherwise you will risk breaking out the corner on the backside of the keyboard tray....... like I did. Fortunately for me, I was able to use some 2-part epoxy (the kind that works on plastic) to glue the hinge back down to the shell. Had the author pointed out those 2 screws in particular, in the pictorial, things would have gone way easier. Hopefully, this will help the next guy.
