What is the purpose of the small ribbon cable, bottom left?
I had a little beer spill on my MacBook Pro this afternoon. Immediately shut down, pulled the battery. Took it apart to clean the components, but found no beer had escaped the left speaker (maybe a little under the keys in the top left—if they get sticky, I'll pull apart and throughly clean the keyboard).
During disassembly, I damaged the connector for the tiny ribbon cable that attaches at the very bottom left of the board (as looking at the upside down machine), near the hard drive connection. The machine boots and behaves normally, except with some bizarre video artifacts when there is dark shading of a certain gradient (in which case, those pixels are a shimmering bright green).
What is the purpose of that cable (which appears to go to the hard drive, so I'm thinking it's a temperature sensor for the drive, or something along those lines. Just trying to figure out if not having it connected is responsible for the video artifacts, or if that's a completely separate issue.
Is dit een goede vraag?
