IMPORTANT: be sure that your laptop is fully shut down and disconnected
from all cables, including the power cable.
1. Remove the 10 Phillips screws that secure the bottom cover to the chassis.
Note: the three right-most screws along the top edge (shown in yellow) are
longer than the rest; install them in the same screw holes at the end of the
process. The rest can be used interchangeably in the remaining screw holes.
