Loosen the four 2x3mm captive screws (yellow) on the bottom of the shell. These screws will not come out.

Unscrew the six 2.5x6mm (blue) screws and remove them using a Phillips #1 screwdriver. The center screw is magnetized and will drop out when the laptop is turned upside down. It can be difficult to get out otherwise.

Remove the clamshell from the top down using a smudging tool. The shell should come off fairly easily without much resistance.
