What ribbon cables am I missing, can I get away without them?
I salvaged a Lenovo Yoga C930-13IKB and want to see if I can get it up and running. From what I can tell, someone previously ripped out the battery and the black protective sheet underneath, damaging 1 or 2 ribbon cables in the process. There was a small thin severed ribbon cable inside the case when I found it. If you look at the motherboard, oriented with the battery located below the board, next to the battery connector on the right there is a large ribbon cable (for keyboard?), and then two smaller ribbon cable connectors that I am maybe missing as nothing is currently plugged into either. They are labeled JP7 and JP14. Am I missing ribbon cables, and what are they for? Can I get away without them?
Edit: I think I've found that JP14 is left empty by design, so I'm not missing anything there. JP7 is shown in the image below, the far right connector indicated by the red arrow. Maintenance manual just says it's part of the upper case, but doesn't say what it's for. Anyone know?
Es esta una buena pregunta?
