Success!!!

My laptop is up and running flawlessly! 

Although, I do have a bit of advice to pass on that wasn't mentioned in the video: make sure there are NO fingerprints on the back of the new keyboard you're installing.  Anywhere.  Or half the keys won't work, you'll have to pull the damn thing back out of the case (BTW, a metal cookie spatula works better than a screwdriver to pop the keyboard out without damaging it), and wipe down the back of the keyboard.  And the cable will pop loose.  And then you'll have to fiddle with it, get the cable stuck back where it's supposed to go and hold it with your pinkie while you try to lock it back in place with a tiny, fragile piece of plastic with the rest of your fingers, while trying not to bend the teeny-tiny metal connector wires that you're trying to lock that little piece of plastic under. 

I'd say I needed at least one more hand, but it would have gotten in the way more than it would have helped. 

Yeah...never drinking coffee around my laptop without using a travel mug to limit child-induced spillage again.  It's nice to know I can replace a keyboard, but it's a right bitch to actually do.
