Using a Torx t5 screwdriver, remove the 6 screws at the top and bottom edges of the back plate

Next, remove the rubber strip that is closest to the hinges of the laptop, as this covers more screws. If you can, try to keep the black adhesive under the strip stuck on the rubber. This will help when reapplying the strip during reassembly.

Using your Phillips-Head #00 screwdriver, remove the 4 screws from the rubber strip cavity. It may help to use tweezers to take them out as they are recessed under the aluminum back.

Using a metal pry-tool, pry the back plate from the housing. This may prove to be difficult as it is set down by strong clasps and the edges are recessed under the frame. I recommend starting from around one of the hinges and going from there, as it is much easier to get under the plate from there.
