reassembly, verify that the wires route over the notch in the frame (secure with Kapton
tape here and over connector) and then along the inside channel away from the front
edge.

5. Testing the computer should include powering on, checking for sound from the
speakers and that the sleep LED light works. The headphone and line in ports should
be checked.
