Connection to uppercase not covered in guides.
Step 10 of the guides to remove upper case doesn't cover how to disconnect a small, short wire connecting the upper and lower cases on the left hand side. This wire 'appears' to be coming from the headphone jack (difficult to tell) and going to some unknown black element covering the speaker grill. I stopped and reassemble my laptop till I figure out what the wire is and how to disconnect it properly.
Has anyone seen this connection in their repair processes, knows what it and how to disconnect/reconnect it?
Is this a good question?
