I took the LCD panel and screen casing off the lower half of the laptop sometime ago to replace the power jack, I took notes of where everything went. Unfortunately some six months later when I get around to re-assembling the laptop my notes are nowhere to be found. Not to worry as reattaching the top half cannot be to problematic? But I seem to have a small lead a thin black wire with an eye on its end that I can't remember the position off, I've attached an image, it is the cable on the left. Any help would be greatly appreciated.
