Flip over the laptop and observe the rubber strips running end to end.

Gently using your fingernails or the edge of a credit card or an iFixIt spudger, pry up a strip from the corner and carefully peel it off.

If done carefully/properly the sticky strip stays intact and you can reuse it if it doesn't get dusty (or your cats don't steal it to play with).

Remove and set aside the MANY screws that hold the base plate to the bottom of the laptop.
